Self-Clinching Technology

Self-clinching technology from PEM® is the idea that revolutionised production fastening. A smart alternative to spot and tack weld products, self-clinching capabilities can be applied to many types of fasteners, including clinch nuts, studs, and standoffs – combining powerful benefits with a broad range of fastener functionality. It’s innovation that enables fewer parts, less total assembly time, and lower installed costs.

  • Provides strong threads in metal as thin as .008” / 0.2 mm
  • Installs using any parallel acting squeezing force
  • High pushout and torque-out resistance
  • Reverse side of metal sheet remains flush
  • No re-tapping needed
  • Low total installed costs
