When using an impact wrench, not any old socket will do the job safely. ToolPRO Impact Sockets are manufactured from strong chrome molybdenum steel with black oxide coating for improved abrasion and corrosion protection. The 6 point design provides reliable operation without stretching or twisting of the socket walls. The deep socket design allows for use on fasteners on long studs such as manifold studs, wheel nuts and head studs. Housed in a black powder coated steel case with a moulded plastic tray to make sure your set stays organised during storage. Don't risk damage to fasteners and sockets, grab this ToolPRO Impact Deep Socket Set and do the job right.
