Abstract

326,031. Guest, E. S. March 20, 1929. Washers.-To prevent loss of the washer 2, the diameter of the plain hole 3 is made slightly smaller than that of the threads. It is first dished, passed over the threads, and then flattened, contracting the hole 3 to its original size. The washer is retained in a recess formed under the bolt head.
