Imperial Nylon Lock Nut

This Imperial Nylon Lock Nut has standard specs that fit most common bolts. Thread sizes cover both metric and imperial types—metric ones go from M3 to M20, and imperial sizes are 1/8" to 1". The thickness varies with the size, just enough to keep a secure hold without being bulky. You can check the product sheet for exact measurements if you need them.

Grades are pretty simple too. There’s a general-purpose grade for daily use, like DIY projects or light machinery. Then there’s an industrial grade for heavier jobs, made with thicker metal to handle more pressure. Both grades use the same nylon insert, which works to prevent loosening from vibration.It’s specs and grades are all standard, so you just pick what matches your bolt size and usage scenario.

We check this Imperial Nylon Lock Nut  carefully during production to avoid faulty pieces. First, we test the raw materials—both the metal body and nylon insert. We make sure the metal isn’t too brittle and the nylon is tough enough to grip bolts without breaking easily.

Then we check the threads. They need to be smooth so bolts can screw on easily, no rough spots that might cause jamming. We also test the locking function—screw the nut onto a matching bolt and shake it to see if it loosens. Every batch has random samples taken for these checks. It goes through all these basic steps to make sure it works as it should for your use.

It’s a simple document with no fancy terms, just what’s needed to prove it meets industry standards.
