PEM® self-clinching studs are installed by placing them in properly sized holes in the sheets and squeezing into place with any standard press. The squeezing action embeds the head of the stud into the sheet. The metal displaced by the head flows smoothly and evenly around the ribs and into the annular groove – creating a flushhead assembly and securely locking the stud into the sheet with high torque-out and pushout resistances.

TPXS (flush-head) Pilot Pins satisfy a wide range of positioning, pivot, and alignment applications. The chamfered end makes mating hole location easy.
  • Meets the ATCA PICMG 3.0 specification.
  • 15° tapered point makes engaging the mating hole easy.

  • 1 The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L”
  • 2 Pin diameter may exceed max. in this region.
  • 3 To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
