Spring pin

A Spring Pin (Roll Pin) is a cylindrical fastener made from spring steel or stainless steel, designed to securely join and align components. It is slightly larger than the hole diameter and compresses during insertion, creating constant radial tension for a strong, vibration-resistant joint.

Features:

  • High elasticity and shock absorption capability
  • Self-retaining design with constant spring tension
  • Resistant to vibration loosening
  • Easy installation without threading or special tools
  • Reusable in many applications
  • Suitable for dynamic and load-bearing assemblies
