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. 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 Socket Set and do the job right.
