** RIB-Lock™ (All New!)

Tested and proven, Rib-Lock™ serrations provide a higher level of vibration resistance compared to other commercial fasteners, retaining nearly 90% of its compressive load after 400 cycles on the Junkers transverse vibration test.

Currently available in both Socket Flange (inch & metric) or Frame Bolts (metric), Rib-Lock™ serrations offer the highest vibration resistance of any standard commercial fasteners.
