Fab-Lok with 300 Series Stainless Steel Sheet Metal Screw, 0.060" - 0.250" Grip Range (Box of 1000)

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.

Features:

• Hex washer head machine screw assembled to a slotted aluminum sleeve and EPDM sealing washer
• After tightening, clamping tines remain in place even if screw is removed. To achieve the published performance data, the screw must remain in the fastener.
• Greater joint integrity with clamping force
• Can be used in blind applications
