What is a lock washer?
A locking washer is a type of washer that’s designed specifically to prevent the bolt with which it’s used from loosening. Like other washers, they’ll distribute the load of the fastened object or objects more evenly. Locking washers go one step further, though, by “locking” the bolts in place.
