9145 | Heyco Nylon Locknuts (50 / Pkg.)

Replaced all the nylon locknuts on my trailer's fender bolts last weekend, and they grabbed the threads perfectly without any stripping. The pack of 50 gives you plenty of spares for whatever else needs securing.

I was pleasantly surprised how snugly these nylon locknuts fit on a standard 1/4" bolt — no wobble at all. The threading caught cleanly on the first try, which saved me time on a quick repair. Definitely a solid choice for basic fastening jobs.

Used a handful of these to secure some studs on a jig, and they threaded on cleanly without any cross-threading fuss. The nylon insert holds tight enough that I didn't need a drop of threadlocker. Fifty in the pack means I won't be running out for a good while.
