SK4-F™ 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 (PEM® Bulletin F) 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
  • SK4-F™ fasteners are now available for installation into stainless steel sheets
