<p>An impact clutch used to fix and tighten bolts, nuts and other parts in appropriate positions on objects, or to loosen and remove such previously fixed and tightened parts. The reliability of operation and the durability of such a clutch has been enhanced through a construction in which the hammer which strikes the striking collar of the impact spindle has been better positioned so that the hammer operates properly within the clutch case, and further, so that the striking force of the hammer on the striking collar is not concentrated on one area only.</p> |
