MS35333-70 | غسالات قفل داخلية مسننة حسب المواصفات العسكرية | فولاذ (200 / عبوة)

Installed these on a motor mount that kept shaking bolts loose, and they hold tight now. The steel teeth dig in just enough without damaging the surface.

I needed a reliable way to keep bolts tight on my garage shelving, and these mil-spec washers dig in perfectly under the head. The steel feels sturdy, and they’re a solid fit for M8 fasteners without slipping.

Installed these on a metal shelving rack that sees daily movement, and after a month of use every bolt is still tight. The steel feels properly hardened and the internal tooth design bites into the surface well. Exactly what you need for vibration-prone assemblies.
