Fab Lok Fastener
Hex Drive Fab-Lok Fasteners (50 Pack)
Vibration, either from inside or outside a building, can make ordinary fasteners loosen and back out. Fab-Lok fasteners combine a screw and a slotted aluminum sleeve to provide resistance to loosening in high-stress and high-vibration environments.
