Custom 65Mn Spring Steel Black Oxide Spring Type Straight Pins
Custom 65Mn spring steel black oxide spring type straight pins are precision elastic fastening components designed for secure positioning, shock absorption, and reliable mechanical connection. The custom 65Mn spring steel black oxide spring type straight pins are manufactured from high-carbon spring steel with excellent elasticity, fatigue resistance, and mechanical strength.
The custom 65Mn spring steel black oxide spring type straight pins feature a straight cylindrical spring design that provides continuous radial force after installation. With black oxide surface treatment, these pins offer improved surface protection, reduced glare, and enhanced appearance for industrial applications. They are widely used in machinery, automotive components, automation equipment, and precision assemblies requiring stable elastic retention.
Product Overview
Custom 65Mn spring steel black oxide spring type straight pins are engineered for applications requiring both positioning accuracy and elastic performance. Unlike rigid locating pins, spring type straight pins can absorb vibration and compensate for dimensional variations during assembly.
The custom 65Mn spring steel black oxide spring type straight pins provide reliable holding force through elastic deformation. The 65Mn spring steel material offers high hardness, excellent resilience, and strong fatigue resistance, making these pins suitable for repeated loading conditions.
As a specialized industrial fastener, these spring pins are commonly used by OEM manufacturers, equipment builders, and engineering companies requiring customized dimensions and stable performance.
