304Cu Stainless Steel Fastener Wire Skin Pass Soap Coated Wire for Screw and Bolt Manufacturing

Product Introduction

304Cu stainless steel fastener wire is a specialized wire material designed for cold heading and fastener manufacturing applications, including screws, bolts, nuts, and precision metal components.

Made from AISI 304Cu stainless steel, this wire contains copper elements to improve cold forming performance and is suitable for manufacturing processes that require good formability and stable processing conditions.

The wire is processed through skin pass drawing and soap coating treatment, providing a smooth surface condition and lubrication support during cold heading operations. The soap coating helps reduce friction between the wire and tooling, supporting efficient forming processes.

We supply customized 304Cu stainless steel fastener wire with different diameters, surface conditions, and mechanical properties according to customer requirements.
