MS35333-136 | غسالات قفل داخلية مسننة حسب المواصفات العسكرية | فولاذ (100 / عبوة)

I was replacing some loose brackets on my trailer and these washers locked everything down tight—the internal teeth really grab the bolt head. No issues with vibration so far.

The teeth bite into the bolt head with real authority—I torqued them down on a vibrating motor mount and they held perfectly after a week of runtime. Pack of 100 means I've got spares for every project ahead.

Installed these on a vibrating conveyor motor and haven't had a single fastener back off since. The steel teeth really bite into the mating surface, much better than split lock washers I've used before.
