Product Specification

Cold Heading Stainless Steel Wire for Precision Fasteners

Product Introduction

Cold Heading Stainless Steel Wire is designed for manufacturing precision fasteners and cold-formed stainless steel components.

The wire is suitable for cold heading, upsetting and other forming processes used to produce screws, bolts, nuts, rivets, pins and related hardware components.

Available diameters range from 0.15–12mm. Material grade, wire diameter, delivery condition, tensile strength and surface condition can be selected according to the forming process and finished component requirements.

For cold heading applications, wire selection should consider the component geometry, deformation level, heading ratio, number of forming stages, die design and lubrication conditions.

Product Specifications

Applications

Precision Fasteners

Cold heading stainless steel wire is used as raw material for precision fasteners such as:

• Screws

• Bolts

• Nuts

• Rivets

• Pins

• Studs

• Washers

• Other formed fasteners

The wire specification should be matched with the finished fastener dimensions and forming process.

Cold-Formed Components

The wire can also be processed through cold heading, upsetting and other forming operations to manufacture industrial components.

Material grade and delivery condition should be selected according to the required deformation and number of forming stages.

Small Stainless Steel Hardware

Fine and medium diameter stainless steel wire can be used for small hardware components where dimensional requirements and repeatable forming conditions need to be controlled.

For precision components, wire diameter tolerance and mechanical properties should be specified together with the material grade.

Product Advantages

Designed for Cold Heading

The wire is intended for cold heading and cold forming processes, where the material undergoes localized deformation to create the required fastener geometry.

The appropriate wire condition should be selected according to the deformation level and forming sequence.

0.15–12mm Diameter Range

The available diameter range is 0.15–12mm, covering fine wire and larger specifications for different fastener and formed-component designs.

The required diameter should be determined according to the blank size, finished dimensions and forming equipment.

Flexible Mechanical Requirements

Tensile strength and delivery condition can be specified according to the selected material grade, wire diameter and forming requirements.

For cold heading, mechanical properties should be evaluated together with the required amount of deformation rather than by diameter alone.

Suitable for Precision Fasteners

The wire can be used for screws, bolts, nuts, rivets and other formed fasteners.

For precision applications, the purchasing specification should include wire diameter, dimensional tolerance, material grade and mechanical requirements.

Multiple Surface Options

Bright surface and customized surface requirements can be considered according to the forming equipment, lubrication system and subsequent processing.

Cold Heading Wire Selection Guide

1. Confirm the Material Grade

Select the required stainless steel grade according to the finished fastener's material requirements, forming characteristics and service environment.

2. Confirm the Wire Diameter

The available diameter range is 0.15–12mm.

The selected diameter should correspond to the required blank size and finished fastener dimensions.

3. Define the Mechanical Condition

Specify the required tensile strength and delivery condition according to the amount of cold deformation.

Soft or semi-soft conditions can be considered for applications requiring substantial forming.

4. Evaluate the Forming Process

Consider the following factors:

• Heading ratio

• Deformation level

• Number of forming stages

• Die geometry

• Lubrication

• Forming speed

• Finished component dimensions

These factors help determine the appropriate wire condition.

5. Confirm Dimensional Tolerance

For precision fasteners, wire diameter tolerance can directly affect blank volume and finished component dimensions.

The required tolerance should therefore be specified before production.

Quality Control

For cold heading stainless steel wire, quality should be evaluated using measurable technical parameters.

Depending on order requirements, inspection may include:

• Chemical composition verification

• Wire diameter measurement

• Dimensional tolerance inspection

• Surface inspection

• Tensile strength testing

• Delivery condition verification

• Material certificate

• Inspection report

For precision fastener production, the acceptance criteria should be confirmed before manufacturing.

Packaging and Supply

Cold heading stainless steel wire can be supplied in coils according to wire diameter, production equipment and customer requirements.

Coil dimensions, weight, labeling and packaging can be customized according to handling and downstream processing requirements.

For long-distance transportation, packaging should also be selected according to the customer's storage and transportation conditions.
