Product Parameter (Specification)

Product Feature

1. High-precision stepped design

Formed by cold heading in one process. Diameter difference at the step is controlled within ±0.02mm. The step surface is smooth and burr-free, Qimao Metal Manufacturer ensuring accurate positioning and preventing over-insertion.

2. High strength and durability

Cold Heading Stepped Dowel Pin for Machinery and Automotive heading maintains complete metal flow lines with no cutting weak points. Work hardening improves tensile strength and shear resistance. Stronger and more durable than machined pins.

3. Excellent material properties

Made of quality carbon steel, alloy steel, or stainless steel etc. Hardness reaches HRC25-40 after heat treatment. Good corrosion resistance and wear resistance for harsh environments.

4. Easy and fast installation

No secondary machining needed. It will be pressed directly into holes. Suitable for automatic assembly lines to improve production efficiency.

5. Good dimensional consistency

Cold heading process ensures consistent size from batch to batch. High surface finish and good interchangeability.
