1/2-Inch Drive by 10 Impact Extension Bar High Carbon Steel

* Work faster and avoid unnecessary disassembly steps with Impact Extension. * Engineered for use with impact drivers it reaches past obstructions or into tight narrow spaces and delivers the torque needed to break loose stubborn fasteners. * A spring-loaded detent ball securely latches onto sockets preventing them from being dropped or left sticking on fasteners. * The through-hole in the drive end locks onto the tang of impact wrenches or drivers. * To protect against rust and corrosion the black oxide finish absorbs and holds oil repelling moisture.
