K-Lock (Keps) Nuts - (USS) Coarse Thread

K-Lock (Keps) Nuts - (USS) Coarse Thread

K-Lock nuts, also called KEPS nuts, come with an external tooth lock washer already attached. The washer spins freely on the nut, so it can't get lost and goes on in one step. As the nut tightens, the teeth bite into the surface to resist loosening. This page covers coarse thread and machine screw sizes from #4-40 to 3/8"-16, all zinc plated.

FAQ

What is the difference between a K-Lock nut and a KEPS nut?
They are the same thing. K-Lock and KEPS are common names for a hex nut with an attached external tooth lock washer.

Why use K-Lock nuts for electrical grounding?
The washer teeth cut through paint and oxide, which helps make a good metal-to-metal contact.
