Combination Set 1/4", 3/8", 157-PCS - MEDIUM

This 157-piece set covers the essentials for your 1/4” and 3/8” drives. From 1/4” to 3/8” sockets and ratchets, Allen keys, Torx and more. Sonic Ratchets and Sockets are made from Chrome Vanadium steel while bit sockets are made from 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.
