Grooved Pin with Head

Grooved pins with head are locating pins with axial grooves machined along the body. These grooves create elastic deformation during insertion, generating strong holding force without the need for threads or adhesives.

The integrated head serves as a stop, simplifying installation and preventing over-insertion. This design is ideal for anti-vibration and anti-loosening applications in structural assemblies.

​Product Features

  • Pin body features three symmetrical axial grooves for strong frictional engagement

  • Interference-fit design provides secure positioning in applications where slippage is not allowed

  • Integrated head acts as a stop, ensuring consistent insertion depth and easier removal

  • Once installed, the pin firmly grips the hole wall, resisting loosening or displacement

​
