PEM® KEYHOLE® Standoffs and sheet joining fasteners are designed so that a PC board or panel can be quickly slipped into place and then removed from an assembly by simply sliding the board sideways and lifting it off. These standoffs and fasteners can save valuable time and dramatically reduce the amount of loose hardware required.

Type SKS-R™ fasteners are designed so that two sheets can be quickly joined flat against each other. Typically, several fasteners are used with one standard PEM® threaded F™ flush nut which accepts a screw to secure the sheets against any unwanted movement.
  • Allow detachable spacing of two sheets
  • Clinch feature mounts fastener permanently and flush or sub-flush into metal sheet
  • Unique barrel design allows for quick “panel-on-panel” attachment and detachment
  • Can be clinched into blind hole where concealed head is required
  • Makes horizontal or vertical component mounting possible
  • SKS-R™ fasteners are designed to provide high side-load in verticle component mounting applications
  • SKS-R™ fasteners are available for various top sheet thicknesses and hole sizes
