ABSTRACT:
A tool is provided which incorporates a ring gauge into which the external tapered threads of a pipe are screwed by hand until tight, at which time a mechanical impulse of predetermined, consistent amplitude and duration is applied to the pipe-gauge combination from a hammer portion of the tool propelled, by rapidly-released spring energy against an anvil portion of the tool, the impulse being immediately coupled to the joint between the pipe threads being checked and the ring gauge, for overcoming any dirt or nicks in the thread which are restricting the engagement of the thread by the ring gauge.
