Product Content Description:

Also called vibration-resistant lock washers and lock set pairs, the set consists of two pieces: a top and a bottom washer.

These reusable washers have wedges on one side, which should be installed interlocked, and radial teeth on the opposite side. When the screw or nut is tightened, the teeth bite into the screw head or nut and the mating material to prevent slippage, while the wedges increase tension to resist loosening.

Nordlock washers are used in numerous industries such as: energy, transportation, mining and quarrying, construction and bridge building, manufacturing and processing, ship building, forestry and agriculture, heavy vehicles, and military.
