201 Stainless Steel Screw Wire for Cold Forming
Product Introduction
TOPONE 201 stainless steel screw wire is designed for manufacturers producing screws, fasteners and other cold-formed wire components.
The wire is available in diameters from 0.15–12mm, with 0.6mm as a featured specification for the original product. Bright and soap-coated surface options are available according to the requirements of the forming process.
The current product specification lists 201 stainless steel, hard condition and a tensile strength of 1750 N/mm² for the 0.6mm specification. These parameters should be confirmed against the customer's required standard and production process before ordering.
For screw manufacturing, wire diameter, material condition, tensile strength, surface condition and forming requirements should be evaluated together. The appropriate wire specification depends on the geometry of the screw, degree of deformation and cold-forming process.

The original page specifies 0.6mm diameter, 201 grade, hard condition and 1750 N/mm² tensile strength. These values should not automatically be applied to the complete 0.15–12mm range; mechanical properties should be confirmed by diameter and order specification.
Why Use 201 Stainless Steel Wire for Screw Manufacturing?
Suitable for Selected Cold-Forming Applications
Screw manufacturing often involves substantial plastic deformation during cold heading or cold forming.
Therefore, the wire needs to be selected according to:
-
Material grade
-
Wire diameter
-
Mechanical condition
-
Tensile strength
-
Surface condition
-
Screw geometry
-
Forming sequence
201 stainless steel can be considered for selected fastener applications when its material properties and corrosion requirements are compatible with the finished component.
0.15–12mm Diameter Range
TOPONE supplies 201 stainless steel wire in a 0.15–12mm diameter range.
The 0.6mm specification featured on this page is suitable for applications requiring a fine wire diameter, while other sizes within the range can be selected according to screw dimensions and forming equipment.
Diameter tolerance should be specified together with the applicable material standard when dimensional control is critical.
Bright and Soap-Coated Surface Options
The product is available with bright or soap-coated surfaces.
Surface selection should take into account the customer's cold-forming equipment, lubrication method and subsequent finishing process.
For cold heading, surface condition is particularly important because the wire passes through tooling and undergoes plastic deformation during forming.
Defined Mechanical Specification
The featured 0.6mm product is listed with a hard condition and 1750 N/mm² tensile strength.
For other diameters, tensile strength and mechanical condition should be confirmed separately rather than assuming the same value across the entire diameter range.
This is especially important when the wire is used for multi-stage cold forming.
Applications
Screw Manufacturing
201 stainless steel screw wire can be used as raw material for selected screw production processes.
Typical applications include:
-
Small screws
-
Machine screws
-
Fasteners
-
Pins
-
Rivets
-
Other cold-formed wire components
The actual grade should be selected according to the required corrosion resistance, forming characteristics and final application.
Fastener Manufacturing
The wire can be used for selected stainless steel fastener applications where the 201 grade meets the material and environmental requirements.
For applications involving high chloride exposure or more demanding corrosion conditions, another stainless steel grade may be more appropriate.
Wire Forming
The wire can also be processed into selected clips, hooks and other formed wire components when the specified mechanical condition is suitable.
Spring-Related Applications
The original product page lists spring, screw and wire-form applications.
However, spring manufacturing should be evaluated separately because spring wire requires specific consideration of tensile properties, spring geometry and forming requirements.
For dedicated spring production, a dedicated stainless steel spring wire specification is preferable.
201 Stainless Steel Wire: Material Considerations
201 stainless steel contains less nickel than common 300-series grades and uses manganese as an important alloying element.
This makes 201 a material option for applications where the required combination of cost, mechanical properties and corrosion resistance is compatible with the working environment.
For screw manufacturing, material selection should therefore consider the actual service conditions rather than choosing 201 solely based on material price.
Where the finished fastener will be exposed to marine, high-chloride or more corrosive environments, 304 or 316/316Lmay need to be evaluated instead.
How to Select 201 Screw Wire
1. Confirm the Screw Dimensions
Start with the finished screw diameter, head design, thread geometry and forming sequence.
These parameters determine the required starting wire diameter and forming reduction.
2. Confirm the Wire Diameter
The available product range is 0.15–12mm.
The featured product specification is 0.6mm, while other diameters can be specified according to the finished component.
3. Confirm Mechanical Condition
Hardness and tensile strength influence how the wire behaves during forming.
The current 0.6mm specification is listed at 1750 N/mm² tensile strength. Other sizes should be confirmed individually.
4. Select the Surface
Choose bright or soap-coated surface according to the forming equipment, lubrication requirements and subsequent processing.
5. Confirm the Material Standard
The product can be specified according to applicable AISI, ASTM, DIN, JIS or GB requirements.
The exact standard should be confirmed before production.
Technical Specification Checklist
For screw-wire purchasing, customers can provide:
Grade → Diameter → Tolerance → Tensile Strength → Surface → Standard → Screw Type → Quantity → Packaging
For example:
AISI 201 / 0.6mm / hard / 1750 N/mm² / bright surface / specified standard / screw manufacturing / coil packaging
This gives the manufacturer the key information needed to review the wire specification before production.
