Products & specs at a glance
Automotive fasteners rely on cold-drawn low-carbon wire that behaves predictably during cold heading and roll-forming. OSSO Wire supplies automotive tier-2 fastener manufacturers across Türkiye, Central and Eastern Europe, and the Americas. Our discipline on tensile scatter within a single coil, on incoming wire-rod inspection, and on documentation makes us a serious supplier for buyers who need PPAP-ready material.

Where our wire ends up
Cold-heading fastener stock
Consistent tensile lets the header run without adjustments. Bright-drawn surface extends die life and reduces cosmetic defects.
Bolt & screw production
Ø3–10 mm cold-drawn wire delivered in bobbins or basket coils to match your feeder capacity.
Spring wire (suspension, seating, actuators)
Cold-drawn or oil-tempered stock with tight tensile scatter for predictable spring rate.
Welded automotive assemblies
Straightened cut-to-length wire for welded frames, brackets and mesh parts.
Under-hood clip & retainer stock
Small-diameter wire for automated forming lines.

Frequently asked questions
Are you IATF 16949 certified?
We align with IATF 16949 process discipline — change control, quality gates, corrective action, documented supplier development — while working toward formal certification. Ask for our current status during qualification.
Can you support PPAP for a new fastener part?
Yes. We support initial sample inspection, capability studies on tensile and diameter, documented process audit if practical, and volume ramp planning.
What is a typical tensile scatter within a single coil?
On our cold-drawn fastener line we typically hold ±30 N/mm² or tighter within a coil. Ask us to document scatter for your specific grade and diameter.
Do you supply oil-tempered spring wire?
Cold-drawn spring stock — yes. Oil-tempered as a finished condition — discuss with our technical desk.
