Wedge Lock / Lock Rite / Rib / Nord Lock Washer

Sonic Industries offers Wedge Lock / Lock Rite / Rib / Nord Lock Washer. These are radial teeth on the opposite side. The locking washers are supplied and installed in pairs, cam face to cam face, and when the bolt and/or nut is tightened the teeth grip and seat on the mating surfaces. The washers are locked in place, allowing movement only across the face of the cams. Any attempt by the bolt/nut to rotate loose is blocked by the wedge effect of the cams, which positively locks the fastener even when it is subjected to vibration or dynamic loads.

Advantages:

• Maximum safety
• Resist loosening caused by vibration
• Ease of assembly and disassembly
• Locking function is not lost by lubrication
• Positive locking at low and high preload levels
• Same temperature characteristics as standard bolt/nut
• Reusable up to 5 times
