Don't struggle with a hex key to get the job done, do it in a fraction of the time using your favorite 3/8-inch drive ratchet or an electric drill / impact driver and a STEELMAN PRO 78382 3/8-Inch Drive x 4mm Metric Hex Bit socket. With a hex bit machined from high-strength S2 steel to prevent twisting and deformation under high loads set into a durable chrome vanadium steel socket, this tool accessory is designed for long-term service. For easy identification, the socket has easy to read size markings permanently laser etched into the steel that won't wear or fade away. To keep it securely attached to ratchets, extension bars, and adapters, the socket feature a ball detent recess on the drive end to ensure maximum torque transfer. The drive end also has corner recesses inside it that transmit applied force from ratchets and drivers to the flat sides instead of focusing it on the corners which can lead to slippage, rounding, and premature tool failure. Designed and constructed to meet or exceed ASME tool performance standards, this tool can stand up to the rigors of any professional workshop while being just as handy in the home mechanic's garage.
