Your socket set can't do this! In those hard-to-reach places, Grip-Tite Super Sockets hold bolts and nuts straight and true, so you can install or remove them easily, without losing them (not magnetic). Grip-tite Super Sockets remove extremely damaged and rounded bolts and nuts. Everything you need - 7 standard length sockets with a rugged quick release teardrop ratchet in a durable plastic case.
