Part # SK4F-6060-6, SELF-CLINCHING KEYHOLE® FASTENERS - SK4F™ - Unified
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.
SK4F™ standoffs
can be used for spacing or mounting of replaceable components. Typically, several standoffs are used with one standard PEM® threaded standoff which accepts a screw to secure the board or component against any unwanted movement.
Allow detachable spacing of two sheets
Clinch feature mounts fastener permanently and flush into metal sheet
Unique barrel design allows for quick attachment and detachment
Makes horizontal or vertical component mounting possible
SK4F™ standoffs are available for installation into stainless steel sheets
