    Bolts Don't Back Out! - The Vibe-Lock TM vibration proof lock fastener is extremely vibration proof and provides the ultimate lock. It utilizes a patented locking washer and clip to lock the bolt in place. The ease of installing and removing the Vibe-Lock beats the competition hands down.

    Easy Installation - Simply install the Vibe-Lock TM bolt by gently tightening the set screw to unlock, torque the bolt, then back off the set screw to relock. This action locks the bolt in place in place so you can rest assured that the bolt will not loosen due to vibration, heat or torque dependence.

    Easy Removal - The Vibe-Lock TM can be removed simply by tightening the set screw to unlock.

    Use Them Time and Time Again - These fasteners are made of only the finest alloys allowing the same fastener to be used over and over while providing the same locking ability time and time again.
