General description Complete set of deep single Hex (6pt) 3/8""D sockets in a useful range of sizes from 10mm to 17mm. Ideal for car engine maintenance and anywhere that regular sockets are too short for access. The six-sided socket head drives from the flats to provide more torque, useful for freeing seized nuts & bolts, while avoiding the risk of rounding. The socket has slightly convex internal faces and drilled out corners for a solid grip, even on damaged fastener heads. Manufactured from durable chrome vanadium steel with a polished finish and supplied on a socket rail for convenient, easy access storage.
