MS35338-143B | حلقات قفل مشقوقة حسب المواصفات العسكرية | فولاذ (100/عبوة)

Used the whole pack re-securing a workbench frame and a trailer hitch that kept rattling loose on gravel roads. The steel feels properly hard, and the split design really bites into the bolt and surface under vibration. One hundred for this price is a solid deal.

Used a few of these on my lawn mower deck where the bolts kept working loose, and they’ve held tight through two heavy mows now. The steel is solid and they bite into the fastener just like you’d want from a split washer.

Came in a tidy 100-pack, and the steel finish looks proper for the price. I've used them on a few vibration-prone assemblies and haven't had a single fastener back out since.
