The impact extension set is made of heat-treated CR-V steel for superior hardness and can withstand high torque from impact tools

Black phosphate finish provides better protection from rust and corrosion resistance than traditional black oxide finish

The spring-loaded detent ball design will ensure a tight and secure fit into sockets. Chamfered ends allow smooth insertion onto fasteners and reduce the damage to edges

These socket extensions provide extra length to access hard-to-reach fasteners and are perfect for handling fasteners in tight workspaces
