Our SHOCKWAVE™ Lineman’s 1/2" Drive 3/8" Hex Bit Sockets are designed to be the most durable hex bit sockets while providing the best access into tight spaces. A 1-piece design allows for the hex bits to better withstand the torque of power tools. A 1-3/4" hex fastening depth will allow these bits to fit the most common connections and hardware utilities that electricians will encounter. An overall compact profile compared to some competitive hex bit sockets will fit more connections.
