Rated 5 out of 5Â by Verified Reviewer M8 Nylon lock nuts.
Good quality & good value, just the ticket, used to secure a security fixing - perfect because cannot be losened without access to both sides & can't vibrate loose.

Its a Nyloc Nut, It can be used on bolts. Oh yeah it works just as well on machine screws. You thread it on, tighten it down and it stays there, PERFECT.
