PEM® KEYHOLE® Standoffs 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. PEM KEYHOLE fasteners can save valuable time and dramatically reduce the amount of loose hardware required. Type SKC can be used for spacing or hanging of replaceable components. Typically, several SKC standoffs are used with one standard PEM threaded standoff which accepts a screw to secure the board or component against any unwanted movement.

Type SKC - Allows detachable spacing of two sheets
  • Clinch feature mounts fastener permanently into metal sheet.
  • Unique barrel design allows for quick attachment and detachment.
  • Head is flush with one side of metal sheet.
  • Makes horizontal or vertical component mounting possible.

  • 1 Fastener will provide flush application at minimum sheet thickness.
  • 2 HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell.
  • 3 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”
