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®more
