K-T Industries 1-5320 Socket Set, Chrome Vanadium Steel, Specifications: 3/8 in Drive Size, 21-Pieces

The perfect tool box organizer. Performance, K-T sockets feature a special non-slip design that drives the fastener from the sides of the hex instead of the corners. This allows up to 15 to 20% more turning power without rounding corners and destroying the fastener. Non-slip sockets also grip fasteners that were previously damaged by other tools. Chamfered recessed socket edges assure an easy fit on fasteners. Quality, drop-forged chrome vanadium alloy steel is one of the best and strongest alloys available.
