Carbon Steel Nickel Plated Tool Dowel Pin, Anti-Rust Mechanical Positioning Pin
Product Overview
This Carbon Steel Nickel Plated Tool Dowel Pin is a common and practical mechanical positioning hardware. Made of high-quality carbon steel base material and finished with uniform nickel plating on the surface, this dowel pin combines stable structural hardness and excellent anti-rust performance. It is widely used for precise positioning, alignment and fixing of tooling fixtures, mechanical equipment and assembly jigs, ensuring stable and consistent assembly accuracy for industrial machinery matching.
Product Features
Carbon Steel Base, Stable Hardness
Adopting high-strength carbon steel material, the tool pin features good rigidity and compression resistance. It is not easy to deform during repeated assembly and extrusion, maintaining stable structural performance for long-term tooling use.
Nickel Plated Surface, Anti-Corrosion & Anti-Rust
The outer surface is treated with fine nickel plating process. The coating is uniform and smooth, effectively isolating air and moisture. It greatly improves oxidation and corrosion resistance, avoiding surface rust and discoloration even in conventional humid workshop environments.
High Precision Size & Smooth Surface
Precision machined with strict tolerance control. The pin body is smooth with no burrs, ensuring tight matching with assembly holes. It realizes accurate positioning, flexible installation and replacement, and provides good interchangeability for batch assembly.
Excellent Positioning Stability
Standard cylindrical structure ensures close fitting after installation. It effectively reduces assembly deviation and component shaking, improving the overall stability and consistency of mechanical tooling assembly.
Application Scenarios
✅ Tooling fixture positioning and assembly dowel pins
✅ Mechanical equipment alignment and fixing pins
✅ Automation jig precision locating hardware parts
✅ Industrial machinery assembly and replacement accessories
