TENSION INDICATING WASHER UNIT

摘要

A multipiece, preassembled washer unit incorporating an upper washer and a lower conical washer with a ring gauge interposed between the outer marginal surfaces of the washers so that the gauge is clamped between the superimposed washers upon compression of the unit to a predetermined amount. The clamping of the gauge being indicative of a predetermined accurate tension level in the joint. The ring gauge including means to accurately size itself and thereby accommodate and/or minimize errors due to tolerances in cold headed clamping members.
