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.KEYHOLE fasteners can save valuable time and dramatically reduce the amount of loose hardware required. Type LSKC-F is designed so that two sheets can be quickly joined flat against each other. Typically, several Type LSKC-F fasteners are used with one standard threaded Type F flush nut which accepts a screw to secure the sheets against any unwanted movement.
