Customer Reviews (4.8 / 5 · 5 reviews)

Steven ★★★★★

The teeth bite into the fastener head immediately, and I’ve had zero loosening on my mower deck after a few bumpy hours. Each washer feels consistent and solid, just what you need for vibration-prone spots.

Thomas E. ★★★★★

These teeth bite into the steel nicely, I used them on a trailer hitch bracket that gets constant vibration and the bolts haven't budged. The 100-count package is a solid value for keeping spares in the shop.

Violet ★★★★★

Installed these on a small engine mount and the positive locking action from the internal teeth made an immediate difference. No more retightening after each use.
