Thickened Nylon Lock Nut

Using this thickened nylon lock nut  is pretty straightforward, mostly for keeping bolts from loosening on their own. First, make sure the nut size matches the bolt thread—no forcing it if they don’t fit. Put the nut onto the bolt by hand first; twist it until it touches the surface of the part you’re securing.

Then use a wrench to tighten it down. You’ll feel a bit more resistance when the bolt hits the nylon insert inside—that’s normal, it’s what stops it from slipping later. Don’t over-tighten though, or you might damage the nylon part. It works well for things like small machinery, DIY projects, or any place where vibration could loosen regular nuts. Thickened Nylon Lock Nut doesn’t need extra washers most of the time, but you can add one if the surface is uneven.

We package this nut to keep it safe during shipping and easy to handle. For small orders—like 100 to 500 pieces—they go into clear plastic bags. Each bag has a simple label with size, quantity, and material, so you can quickly check what’s inside. These bags are then put into cardboard boxes with dividers to stop the nuts from scratching or tangling up.

Bulk orders—1000 pieces or more—use thick corrugated boxes or sealed plastic tubs. We line the inside with bubble wrap or foam to prevent them from moving around. All outer packaging has a moisture-proof layer to keep metal nuts from rusting. If you need custom packaging, like blister packs for retail, just let us know. Thickened Nylon Lock Nut follows these basic packaging rules to make sure it arrives in good condition, no matter the order size.

Can this nut be reused after I take it off? Will the locking function work as before?

A: It can be reused a few times, but the locking effect will get weaker each time. The nylon insert inside grips the bolt to prevent loosening—taking it off and on wears down that grip. For regular, non-critical jobs, reusing 2-3 times is okay. But if it’s for machinery or parts that vibrate a lot, I suggest using a new one each time. Don’t force it when reinstalling; if you feel it’s too loose when screwing on, replace it right away to avoid issues.
