Disclosed is a thread chase or tap capable of being inserted past damaged threads of a female threaded coupling and then rotated back to repair the damaged threads. The thread chase can be selectively expanded to engage chase blocks having cutting teeth against threads. Thereafter, a user can rotate the thread chase in a direction sufficient to cause the thread chase to move axially out of the female threaded coupling. Upon doing so, the chase blocks can be pushed outwardly and engage undamaged threads, and rotated so as to move upward and repair damaged threads.

Internal thread chase

A compact head body hammer that requires less clearance to operate as compared to conventional hammers. The hammer does not include a secondary tool located on the rear of the hammer, for example, a pry or a wedge. In omitting these secondary tools, the hammer provides more clearance and allows greater pull back prior to the user striking an object. Further, the hammer head can weigh substantially the same as a conventional hammer head, for example, seven ounces, so that the striking power of the hammer is not compromised by the compact nature of the hammer. The centerline of the hammer head base can be offset with respect to a centerline of the hammer handle, which also provides less mass at the rear portion of the hammer head and allows greater pull back prior to striking the object.
