PEM® self-clinching, flush-head studs with X-Press™ threads are typically usedwith push-on or other plastic fasteners. The coarse thread design of the threadreduces assembly time and provides high retention force.
These self-clinching studs are installed in metal sheets by pressingthem into place with any standard press. They can also be installed usingautomated equipment during the in-die process.
PEM® studs with X-Press™ threads are available with 5 mm and 6 mm metricthreads. Lengths range from 10 mm to 25 mm.

Features and Benefits
  • Offers fast, reliable attachment.
  • Reduces assembly time.
  • Allows for lighter assembly.
