Top 11 Screw Manufacturers and Suppliers in Turkey (2026 Guide)

TURKEY · SCREW SOURCING REVIEW · VERIFIED 27 OCTOBER 2026

For a screw project in Turkey, start by separating three routes: an OEM production programme, a catalog construction/assembly screw and a supplier coordinating a custom request. The 11 companies below have different roles within those routes; a factory-focused enquiry and a broad stock enquiry should not use the same shortlist automatically.

Norm, UGC and Çetin provide industrial manufacturing directions with specific screw evidence. Teksan, Vis Vidasan, Selectron and Acar offer different standard/custom combinations. Ezel, Sertel and Boztaş bring distinct screw families within broader operations, while Teknik Vida is retained as a supplier/custom-enquiry option with a narrower factory-evidence boundary.

The shortlist groups Turkish screw manufacturing and supply options by product fit and purchasing role, rather than company size or market share.

Shi Shi Tong, the publisher, manufactures custom screws in Shenzhen, China. Our separately disclosed overseas option is not counted as a Turkish factory, warehouse or local-stock supplier.

Quick Answer: Match the Screw to the Turkish Supply Route

For repeat drawing-based production, compare the accepted geometry, manufacturing route and sample evidence from relevant manufacturers—not a universal company-size ranking. For roofing, drywall, furniture or a socket-cap reference, start with the exact product family and required application evidence.

For a manufacturing enquiry, confirm the actual producing and finishing sites. For a sourced part, request the maker and product reference. In either case, agree the required dimensional, material and quality records for the selected screw.

Quick Comparison of Turkish Screw Sources

1. Norm Fasteners

Best considered for: Repeat OEM screws, furniture/appliance and drilling/thread-forming requirements
Business location: Main contact: Çiğli, İzmir; screw-production facility: Salihli, Manisa
Business role: screw/fastener manufacturer with group engineering and supply services

Norm’s dedicated screw-production page describes cold forming, drilling-point forming, thread rolling and heat treatment. It distinguishes screw families for furniture, sheet metal, appliances and other assemblies rather than relying only on the group’s bolt-and-nut background.

The page identifies the Salihli screw plant in Manisa separately from the İzmir main contact. It also allocates certain preparation, coating and packaging operations to other group facilities. This is a group process route, not evidence that all operations occur at one address.

For an OEM programme, confirm the accepted part, source allocation and sample requirements. Norm Vida, Norm Cıvata and related group sales names are not added as extra screw entries. Capacity figures, client testimonials and general quality language are not independent part approval.

Before approval: Identify the producing site and group operations for the actual screw; obtain current drawing acceptance and required records.

2. UGC Uğur Gürbüz Cıvata

Best considered for: Machine, tapping, drilling, chipboard, furniture and special assembly screws
Business location: Published factory/company base: Selimpaşa Ortaköy Industrial Zone, Silivri, Istanbul
Business role: screw and cold-formed fastener manufacturer

UGC lists machine, tapping, self-drilling, chipboard, drywall, wood, furniture and window-related screws. These are distinct families; quote the selected thread, head, point and receiving material rather than a general fastener description.

The About and contact sources identify the Selimpaşa Ortaköy base in Silivri, Istanbul. The production menu covers wire preparation, forming/threading, heat treatment, coating and sorting. A process menu helps frame an audit enquiry but does not verify every operation for every part.

Ask for drawing acceptance and the manufacturing and finishing route of the quoted item. Agree the required material, dimensional and quality records for that screw before sample or production release.

Before approval: Match the exact screw category and drawing; request the proposed manufacturing/finish route and project-required evidence.

3. Teksan Vida

Best considered for: Metric screws with custom heads, threads and finish requirements
Business location: Published factory/company contact: Velibaba, Pendik, Istanbul
Business role: standard and special screw/rivet manufacturer

Teksan publishes a metric-screw capability page covering customer-specific head forms, different thread arrangements and finish options. Its wider navigation includes sheet-metal, chipboard and special screws as well as related fastening products.

The homepage identifies screw and rivet production at its Pendik factory and publishes a Velibaba contact. The metric page provides more detail than a general custom-manufacturing statement, but the listed size, strength and finish ranges still require item-specific confirmation.

Use a controlled drawing to clarify the functional head, drive, thread and unthreaded lengths. Ask for the proposed process and sample checks. A top-end length or strength figure is not proof that every slender geometry or material/finish combination is feasible.

Before approval: Obtain acceptance of the exact head/thread, material, strength condition and finish; do not combine unrelated range maxima.

4. Selectron Fastener

Best considered for: Drawing-based screws plus drilling, roofing, tapping, drywall and chipboard families
Business location: Published factory: Köstemir Yolu, Silivri, Istanbul; overseas subsidiaries/contacts listed separately
Business role: standard and non-standard screw manufacturer

Selectron describes standard and non-standard screw production and explicitly invites bespoke fasteners to customer specifications and drawings. Its menu separates drilling, roofing, tapping, drywall, chipboard and special screws.

The company publishes a factory address in Silivri, Istanbul, while listing UK, French and German subsidiaries separately. Those overseas contacts are not presented as additional Turkish manufacturing sites or separate ranked manufacturers.

The company describes cold forming and heat treatment for industrial fasteners. Ask for the proposed material, process, sample records and producing operation for the exact screw.

Before approval: Agree the exact drawing and current legal seller; confirm which manufacturing and testing records apply to the proposed item.

5. Vis Vidasan

Best considered for: Metric, sheet-metal, chipboard and special-drive/stainless screw requirements
Business location: Published company/production contact: Selahaddin Eyyubi, Esenyurt, Istanbul
Business role: standard and custom screw manufacturer

Vis Vidasan identifies chipboard, metric and sheet-metal screws under its related brands and describes customer-specific Torx, hex-socket and stainless directions. Its live metric category provides individual product references rather than only a generic screw label.

The company page publishes its Esenyurt, Istanbul contact and discusses its production building. The related Vissun and Metr-x names are brands within this offer, not additional independently reviewed factories.

Request a controlled product sheet or drawing and confirm the actual dimensional/material combination. Standard cross-references on commercial catalog pages should be checked rather than copied uncritically. General capacity, longevity and quality claims do not establish approval for a particular application.

Before approval: Confirm the exact standard/drawing, drive, material and source; clarify any inconsistent standard cross-references before approval.

6. Ezel Cıvata

Best considered for: Machine, combination, wood, furniture and special fastener projects
Business location: Published manufacturing/company base: Torbalı, İzmir
Business role: screw and formed-fastener manufacturer with distribution activity

Ezel’s screw page separates recessed and slotted machine forms, combination, wood and furniture screws. Its production page explicitly describes manufacture at its own facilities alongside a wider screw, bolt, nut and rivet offer.

The official base is Torbalı, İzmir. A company announcement dated 24 July 2026 reports OBO Bettermann’s majority investment while existing family management continues day-to-day operations. That reported relationship does not turn OBO into an extra independently reviewed Turkish screw factory.

For procurement, confirm the current legal seller and actual manufacturing/source route. Ezel also describes distribution, so do not assume every offered line is made in-house. Ask for the accepted reference, finish and sample evidence rather than relying on a general corporate certificate statement.

Before approval: Agree the exact screw and producing route; confirm current contracting details and required material/finish evidence.

7. Sertel Vida Metal

Best considered for: Drilling, chipboard/MDF, drywall, concrete, panel and collated screw requirements
Business location: Published company/production base: Evciosb industrial area, Akdeniz, Mersin
Business role: screw, wire and fastening-products manufacturer

Sertel’s dedicated screw category includes chipboard, MDF, drilling-point, drywall, concrete, panel and other construction/assembly directions. It is not included merely because it sells screw-driving tools; the screw offer is explicit.

The company identifies its Mersin operation and describes a manufacturing route from raw material through forming, treatment and packaging. The broad integration claim is company-reported and should be checked for the specific screw and finishing process.

For collated or construction products, agree the exact reference, substrate and compatible installation system. Ask for current required assessments and instructions. A product-family name or general quality logo does not establish load capacity or corrosion suitability for every installation.

Before approval: Specify the exact screw, substrate, installation system and finish; request current application evidence for that product.

8. Çetin Cıvata

Best considered for: Metric, sheet-metal, chipboard, thread-forming and concrete screw families
Business location: Published production/company base: Muratbey, Çatalca, Istanbul
Business role: standard and special industrial fastener manufacturer

Çetin has a specific screw page listing metric, sheet-metal, chipboard, thread-forming and concrete-screw directions. The offer is separate from its bolt, nut and other automotive/industrial product menus.

Its company history states that production has operated in the Çatalca factory area since 1996, and the current contact is in Muratbey, Çatalca. The wider Tecde group is background rather than a reason to count every group company as another screw producer.

Request a proposal against the exact drawing or controlled reference and confirm source, process and sample evidence. A broad dimensional range for all fasteners or a list of certificates cannot be applied automatically to the screw being ordered.

Before approval: Match the actual screw and site to the accepted reference and current project-required documentation.

9. Acar Vida

Best considered for: Metric, sheet-metal and special screw enquiries with material/geometry options
Business location: Published company contact: Hızır Reis Caddesi, Pendik, Istanbul
Business role: customer-specific screw, bolt and rivet manufacturer

Acar describes screw manufacture driven largely by customer requirements and identifies metric, sheet-metal and other screw directions. Its company information discusses several wire/material options alongside the later expansion into bolts and rivets.

The current official contact is in Pendik, Istanbul. Kartal appears in the founding history and is not substituted for the present contact address. Published capacity, machinery and certificate statements are not used as independently verified performance claims.

Provide the controlled drawing and ask for exact material, forming and secondary-operation acceptance. Where translated product labels are ambiguous, clarify whether a term describes the screw material, thread type or mating substrate. Do not approve a part from the translated category name alone.

Before approval: Clarify the actual material and meaning of translated product names; obtain drawing-level capability and sample acceptance.

10. Boztaş Cıvata

Best considered for: Socket-head cap and countersunk socket screw enquiries within a bolt/anchor-focused range
Business location: Published company contact: Kayabaşı, Başakşehir, Istanbul
Business role: industrial fastener manufacturer

Boztaş is primarily presented through a broader bolt, anchor, stud and nut range. Its socket-head product page explicitly identifies DIN 912 / ISO 4762 hexagon-socket-head screws, establishing a specific screw connection beyond a generic translation of fastener terminology.

The company identifies Kayabaşı, Başakşehir, Istanbul and describes manufacturing operations. Confirm the producing site, accepted geometry and current capacity and delivery terms for the required order.

Keep the enquiry focused on the exact socket-screw reference and proposed material/grade. Do not extend the company’s anchor or structural-project descriptions into approval of a particular screw. Confirm the actual plant and acceptance records in the quotation.

Before approval: Use the exact screw standard/drawing and confirm material/grade, dimensions and actual producing-site allocation.

11. Teknik Vida

Best considered for: Catalog machine, Torx and thread-forming screws plus drawing-based discussions
Business location: Published business contact: İkitelli OSB, Başakşehir, Istanbul
Business role: screw supplier and custom-production enquiry provider

Teknik Vida’s live technical catalog identifies individual machine and other screw products. Its DIN 7985 page explicitly describes a cross-recessed pan-head screw, while the homepage also invites drawing/sample-based custom-production enquiries.

The site publishes an İkitelli OSB contact in Başakşehir, Istanbul. The available information supports a supplier/custom-enquiry role, but does not establish factory ownership or the actual producing site for every catalog item. It is not labeled as a verified direct factory here.

Clarify the legal seller, actual manufacturer and full part specification before proceeding. Obtain controlled technical data where catalog standard cross-references or option combinations need clarification. Website counters and broad process language are not independent capability evidence.

Before approval: Reconfirm the legal business, actual producer and accepted specification before treating the offer as a direct-factory quotation.

Official resources: Official product / capability page · Company / location source

A More Useful RFQ: Part, Process and Producing Site

The Turkish sources show why group integration and one-site manufacture are different concepts. Norm allocates certain operations to related facilities; other businesses describe a broad process range without proving that every quoted screw follows the same route. Ask the supplier to map the actual item rather than repeating the corporate process menu.

1. Send the controlled drawing or exact catalog reference, including head, drive, point, thread and any shoulder/washer arrangement.
2. Specify material/condition, finish and functional requirements; identify any customer approval or source restrictions.
3. Request the actual legal seller, manufacturer, producing site and relevant group or subcontracted operations.
4. Agree the sample and project-required acceptance evidence before release, including how nonconformities will be addressed.
5. Define repeat-order traceability and source/process-change approval rather than assuming the initial sample settles all future supply.

Do Not Turn a Broad Catalog into a Technical Approval

Several commercial pages mix screw, bolt, rivet and stud categories, and translated labels or standards cross-references may need clarification. Match the actual geometry and controlled standard/drawing. Avoid treating the highest listed diameter, length, strength and finish as one proven combination.

Construction and regulated applications require product-specific evaluation by the responsible project team. A manufacturing address, general ISO/IATF language or industry customer list does not establish a screw’s load capacity, corrosion life or approval for a new joint.

Keep Group Changes and Sales Routes in the Supplier Record

Ezel’s July 2026 company announcement reports OBO Bettermann’s majority investment. Norm’s own sources distinguish screw production and related preparation/coating/packaging functions; STD describes a separate group supply/logistics role. Record those relationships without inventing a second factory from a new brand or sales name.

For the ordered item, reconfirm the current contracting entity and producing source. Overseas subsidiaries, sales offices and local suppliers remain useful contacts but do not independently establish the origin or plant of every catalog screw.

Shi Shi Tong as an Overseas Custom-Screw Comparison

For unusually long/slender screws, special shoulders or non-standard head/drive and thread-length requirements, an overseas custom proposal may be relevant alongside Turkish sources. Compare accepted geometry, process and sample evidence rather than assuming a catalog maximum confirms feasibility.

Our custom screw manufacturing is in Shenzhen. Review the company background and quality-control approach, then send the drawing and demand profile for evaluation. Turkish production, local stock and delivery commitments are not implied.

Turkey Screw Supplier Questions

Does this list contain 11 independent Turkish screw factories?

No. Some suppliers manufacture screws in-house, while others combine production with sourcing or handle custom-order enquiries through partner factories. Confirm who will make and inspect the quoted part.

Why is a bolt-focused manufacturer included in a screw guide?

Only specific screw evidence qualifies it. For example, Boztaş has an explicit socket-head screw product page. A generic bolt, nut or anchor manufacturing statement alone would not establish the same fit.

Can all operations be assumed to take place at the head office?

No. A head office, factory, coating facility and logistics center can be separate. Obtain the actual producing route and relevant outsourced/group operations for the screw being approved.

How should translated screw categories be interpreted?

Clarify the functional geometry, screw material and mating substrate with the supplier. A category translation or commercial standard cross-reference is not a substitute for the accepted drawing and controlled technical data.

Do published upper size limits confirm an extra-long slender screw?

No. Ask for the exact diameter-to-length combination, head/shank/thread details, material, finish and functional straightness requirements. A general range is not proof of all combinations or of a specific manufacturing process.

Which documents matter most before a repeat-production order?

Use the records required by the actual project: accepted drawing/reference, manufacturer/site, material/condition, dimensional and other agreed acceptance evidence, sample approval and change control. General corporate certificates should be checked for current scope rather than treated as product guarantees.

Build a Turkish Shortlist Around the Approved Screw

Use the specific manufacturing or supply route to narrow the initial list, then compare responses to one controlled requirement. OEM forming, construction screws, stainless options and catalog consolidation are different buying tasks; the best fit depends on the part and evidence.

The final decision should identify the accepted product, actual producing source, sample records and repeat-supply controls. That is more actionable than a nominal ranking whose companies all receive the same generic description.
