Description

M2 / M2.5 / M3 / M4 / M5 / M6 / M8 / M14 2-56 / 4-40 / 8-32 / 10-24 / 10-32, 1/2, 1/4, 3/8, 5/16 M2 / M2.5 / M3 / M4 / M5 / M6 / M8 and M2-M8 Assortment Kit 4-40, 6-32, 8-32, 10-32, 1/4 Nylon lock nuts differ from a standard hex nut in that they have a nylon insert secured within the nut. The nylon insert is located in a tapered section located at the back of the nut. When you install the nylon lock nut onto a bolt or threaded stud, the nylon insert wraps around the threads and locks the nut in place. This gives a nylon lock nut a distinct advantage over a lock washer when the bolt or threaded stud is subject to vibration, as the nylon lock nut is unaffected by vibration. Nylon lock nuts are used across a wide variety of industries, including in appliances, computers, furniture, medical equipment, vehicles, sheet metal, and aircraft. Heavier nylon insert lock nuts are used in buildings, on bridges, and in railroad equipment.

    • They work

Well made, good finish, good tolerances. They fit, they work, exact number of items.

    • As expected.
Size: 100pcs M5
Just normal nylock nuts, nothing fancy. The packaging was a bit average though. Some of the nuts ended up loose inside the outer carton. Not too bad though, for something coming from the other side of the world.

decent fit and finish, and good packaging. however, after installing the nut to a threaded rod with a wrench, the nylock could be turned without a wrench, so these are really just standard hex nuts without any locking feature. all the nylock nuts i have used before could not be turned by hand once the nylock engaged. ... show more
