4-40 Hex Keps Nuts / Steel / Zinc
A hex nut pre-assembled with a free spinning external tooth lock washer. The locking action is achieved when the nut is tightened against a bearing surface as the teeth of the lock washer dig into it.
This is the most popular type of locknut because of its versatility, cost and ease of installation. Doesn't gall screw threads.
