When ordinary Allen wrenches are not enough, these bits let you use your ratchet wrench handles to drive hex fasteners with great conviction. When I broke one of these on a stuck set screw, so much energy was released that there was a bright spark at the point of fracture. This is a lesson in why spark-proof brass tools exist for use where explosive gas may be present: hardened steel can and will spark when stressed to the point of failure, or just hit hard enough.
