#### ALLEN AND STAR WRENCHES

Allen and star (Torx® ) wrenches are required more and more to work on vehicles. Allen wrenches are hexagonal and Torx® bits are multi-serrated inserts that fit inside a bolt or screw head rather than lining around the outside of the head. They can be L-shaped tools with their own handles or are available to fit a ratchet handle
