NATIONAL

LOCK WASHER.

Combining Strongest Spring Fastening possible, with positive locking of Nut by rib.

Can be used on any make of bolt or nut, in any place in track.

Same bolt, nut and washer can be used as often as required.

The National Lock Washer is made of steel, hardened and tempered in oil; when in use in track the rib is imbedded in nut (does not cut out metal in nut), thereby upsetting metal of nut and forcing it around bolt, and so locking nut that it cannot jar loose, acting at same time it has all the spring-holding power of the best spring nut lock made.

A trial of the National Lock Washer is requested, as actual use will demonstrate its superiority.

Samples furnished free of expense.
