Product Specification

304HC3 Stainless Steel Screw Wire for Cold Heading

Product Introduction

304HC3 stainless steel screw wire is designed for cold heading, screw machining and stainless steel fastener production. The 3.5 mm specification is suitable for applications requiring controlled forming performance, corrosion resistance and dimensional consistency.

TOPONE supplies 304HC3 stainless steel wire in 0.15–12 mm diameters, with bright, soap-coated and skin-passed surface options. The wire can be supplied in coils or spools according to processing equipment and production requirements.

For fastener manufacturers, selecting the appropriate wire condition, diameter, surface and mechanical properties is important because these factors can affect cold heading, forming and subsequent machining performance.

Technical Specifications

Note: Final diameter tolerance, tensile strength, elongation and surface condition should be confirmed according to the required grade, diameter and forming process.

Why Choose 304HC3 Stainless Steel Wire for Screw Manufacturing?

Designed for Cold Heading Applications

304HC3 stainless steel wire is used for stainless steel screw and fastener production where the wire undergoes forming operations such as heading, upsetting and thread-related processing.

The material condition should be selected according to the forming method, tooling design and finished-part requirements rather than diameter alone.

Multiple Surface Options

TOPONE supplies 304HC3 screw wire with different surface conditions:

• Bright surface for applications requiring a clean and smooth appearance.

• Soap-coated surface for forming processes where additional lubrication is required.

• Skin-passed surface for applications requiring controlled surface characteristics.

Surface selection should be matched with the customer's forming equipment, lubricant and subsequent processing.

Wide Diameter Availability

The available diameter range is 0.15–12 mm, with 3.5 mm as the featured specification on this page.

This range allows fastener manufacturers to select different wire sizes for screws, bolts, nuts, pins and other formed components.

Applications

Stainless Steel Screw and Fastener Production

304HC3 stainless steel wire can be used for manufacturing:

• Stainless steel screws

• Bolts

• Nuts

• Washers

• Rivets

• Pins

• Custom cold-headed components

Automotive and Industrial Components

For industrial fasteners, wire selection should consider the required forming operation, component geometry, material grade and final service environment.

Wire Forming

The material can also be considered for selected wire-forming applications where the required diameter, surface condition and mechanical properties match the forming process.

Product Advantages

1. 304HC3 Material for Fastener Processing

The 304HC3 grade is positioned for screw and cold-heading applications. Material grade selection provides a clear basis for matching the wire with the customer's forming process.

2. 0.15–12 mm Diameter Range

TOPONE provides a broad diameter range from 0.15 to 12 mm, including the featured 3.5 mm specification, allowing customers to select wire according to component dimensions.

3. Flexible Surface Selection

Bright, soap-coated and skin-passed options are available. The appropriate surface can be selected according to forming equipment, lubrication requirements and subsequent processing.

4. Coil and Spool Supply

Wire can be supplied in coil or spool formats. Packing can be discussed according to production equipment, handling requirements and order specifications.

5. Technical Documentation

For industrial stainless steel wire procurement, customers can confirm material grade, diameter, surface condition, mechanical properties and applicable standards according to their production requirements.

Quality & Technical Documentation

For B2B stainless steel wire procurement, quality evaluation should not rely only on appearance. Buyers should confirm:

• Material grade

• Diameter and tolerance

• Surface condition

• Tensile strength

• Elongation

• Chemical composition

• Applicable standard

• Coil or spool weight

• Mill Test Certificate or inspection documentation

For customized requirements, the final specification should be confirmed before production.

How to Select 304HC3 Screw Wire

Before ordering, fastener manufacturers should provide the following information:

1. Wire Diameter
For example, 3.5 mm.

2. Forming Process
Cold heading, screw machining, upsetting or other forming processes.

3. Surface Requirement
Bright, soap-coated or skin-passed.

4. Material Requirement
304HC3 or an equivalent specification required by the customer's standard.

5. Supply Form
Coil or spool.

6. Mechanical Requirements
Tensile strength, elongation, hardness or other customer-specific requirements.

Providing these details helps determine whether the selected wire condition is suitable for the intended production process.
