PEMserter Series 4

Press for installing self-clinching fasteners

This press offers installation of all types of self-clinching fasteners rapidly, reliably and permanently in thin-metal sheets.

Broadly defined, a self-clinching fastener (also known as clinch or captive fastener) is any device, usually threaded, that, when pressed into ductile metal, displaces the host material around the mounting hole, causing it to cold flow into a specially designed annular recess in the shank or pilot of the fastener. A serrated clinching ring, knurl, ribs or hex head prevents the fastener from rotating in the host material once it has been properly inserted. Thus, self-clinching fasteners become a permanent part of the panel, chassis, bracket, or other item into which they are installed.

Key Advantages Of Self-Clinching Fasteners

  • Provide strong threads or attachment in metal as thin as 0.20 mm / .008″.
  • May be installed using any parallel acting squeezing force.
  • Provide high pushout and torque-out resistance.
  • Do not require special hole preparation, such as chamfering and deburring.
  • Reverse side of metal sheet remains flush – no swaged rim protrusion.
  • No retapping necessary after application.
  • Low installed costs.
