Customer Reviews (4.6 / 5 · 5 reviews)

Ava ★★★★★

Spun them onto some machine skids that get constant shaking and they haven't budged in weeks. The nylon locking collar grabs securely without damaging the threads, exactly what I needed.

Amelia O. ★★★★★

These nuts lock tight without a washer, and I didn't have a single one back off after installing them on my trailer's hitch bolts. The nylon insert grips securely even after a few removals.

Scarlett ★★★★★

Used a few of these on my motorcycle’s handlebar clamps and they haven’t budged through a week of bumpy rides. The nylon insert grabs tight without needing a ton of torque.
