Take the leap on this 185-piece Sonic set and you have everything you need for 1/4” and 3/8” ratchets, sockets, and bits. Sonic Ratchets and Sockets are made from Chrome Vanadium steel while socket bits are made hardened tool steel. The Flank Sockets have reliefs in the corners, allowing the socket to bite into the flats of the fastener, mitigating the chance of stripping.
