General description Deep 30mm single Hex 1/2" square drive socket, ideal for car engine maintenance and situations where regular sockets are too short for access. The six-sided socket head drives from the flats to provide more torque, making it useful for freeing seized nuts and bolts while minimizing the risk of rounding. The socket features slightly convex internal faces and drilled out corners for a solid grip, even on damaged fastener heads. Technical specifications Size: 30mm single Hex x 1/2"D Depth: 77mm Material: Chrome vanadium steel with a polished finish Other information Part of a range of individual deep sockets available in various metric sizes from 10mm to 32mm For other sizes, please see Laser Part Nos. 1982 - 1996 (10mm to 31mm)
