Nowadays motorcycles make widespread use of set and cap screws that require hex (also known as "Allen") and Torx wrenches. Such fasteners are very vulnerable to damage from tools with loose tolerances and/or inferior materials. CruzTools socket bit sets are very comprehensive. These sets are professional tool quality, yet priced to meet any budget. Socket bodies are polished chrome, and bits are made from a heat treated chrome vanadium alloy that exceed ANSI standards. Unlike most socket bit sets found elsewhere, all sockets are 3/8" drive so you only need one ratchet or T-handle for all sizes. A reverse laser imprint provides for easy size identification. To help keep your socket drawer organized, each set ships on a rail with handle. Tools are lifetime guaranteed.
