Britool Hallmark 25pc 1/2" Dr. Deep Impact Socket Set Sizes 8-36mm 6pt

The Britool Hallmark 25-Piece 1/2" Drive Deep Impact Socket Set is a professional-grade socket collection designed for demanding automotive, mechanical and workshop applications. Manufactured from premium Chromium-Molybdenum (Cr-Mo) steel and heat treated for durability, these deep impact sockets are engineered to withstand the high torque and shock loads generated by suitable pneumatic and cordless power tools. The 6-point hexagon profile provides secure engagement with fasteners, helping reduce the risk of rounding and fastener damage. Britool's Stress Relief Drive system allows higher torque to be applied while helping distribute loading away from the corners of the fastener. Each socket features a ball retaining groove on every face of the square drive, providing a secure connection with compatible 1/2" drive accessories. Side holes are also provided for optional pin-and-ring retention when additional security is required during heavy-duty impact applications. The complete set is supplied in a tool control EVA foam tray, keeping all 25 sockets organised and easy to identify inside a toolbox, top box or roll cab drawer.
