Nord Lock Washers Install 12/17/12 I decided to add some piece of mind on critical bolted joints on the deuce by installing Nord-Lock washers. These washers prevent loosening of critical bolted joints because the angle between each little wedge on the washer faces is greater than the bolt pitch (angle). Each joint receives a pair of Nord-Lock washers that are harder than any bolts, washers, or nuts (48 Rockwell C). I chose to install the Nord-Locks on the drive shaft flanges first. This would be the front driveshaft, rear driveshaft, transmission-transfer case driveshaft as well as the winch driveshaft.
