M6 Wedge-Lock Washer Details

This Nord Lock style M6 washer from O.S. Engine OS55500005 provides a compact locking solution for M6 fasteners used in RC-scale builds. It is intended for demanding attachment points like engine mounts, motor brackets and gearbox fixings where vibration and shock can lead to loosening.

Fitting is straightforward: set the washer pair against a clean, flat surface with the wedge faces opposing and then tighten the M6 screw or nut as normal. The wedge-lock principle converts bolt rotation into retained tension when exposed to vibration, so ensure proper seating and matched washer orientation for reliable operation. Avoid use on uneven surfaces or damaged threads.

In model tuning and upkeep this washer reduces the need for frequent re-torquing rather than serving as an adjustment tool. Use it where recurring loosening compromises handling or reliability, and pair it with correct thread engagement and torque practice to get the best results during running sessions.

Is flatness of the mating surface critical for these washers?

Yes. For the wedge-lock action to work correctly, the mating surface should be flat so the paired washers sit flush and the wedge faces engage as designed.

Should I use a threadlocker with these washers?

You can, but it depends on the application. The washers reduce vibration-induced loosening and often remove the need for threadlocker, though some users combine both methods for added peace of mind in critical assemblies.

How must the washer pair be oriented during installation?

Install the matched pair so the wedge faces oppose each other across the bolt. Correct orientation is essential for the wedge-lock mechanism to convert rotation into retained tension under vibration.
