Customer Reviews (4.4 / 5 · 5 reviews)

Jason ★★★★★

I needed a reliable way to keep the bolts on my trailer hitch from backing out, and these nuts grab tight without loosening over time. They're a solid choice for any vibration-prone fastening job.

Leo F. ★★★★★

These lock nuts bite down tight and stay put even on greasy tractor bolts. A full thousand in the bag means I won't be running out mid-job anytime soon.

Natalie ★★★★★

Finally, a bag of lock nuts that actually has a thousand pieces—counted three separate handfuls and it checks out. These bite down tight on the threads and haven't budged on my off-road gear after a full day of rattling around.
