Whether you're working under the dashboard of a car, under the hood of a truck, or just trying to give your motorcycle a tune-up, the STEELMAN 55506 8-Piece 1/4-Inch and 3/8-Inch Drive Tamper-Resistant Star Bit Socket Set will help you get the job done. Their special design includes a recess in the center of each bit to allow these socket bits to be used on tamper-resistant and security fasteners in addition to standard 6-point star fasteners. The rugged star / Torx bit heads are machined from high-strength S2 steel that is permanently set into durable chrome vanadium steel sockets. For easy identification, each socket has easy to read size markings hard stamped into the steel that won't wear or fade away. This set includes five 1/4-inch drive sockets for finer, more precision jobs, and three 3/8-inch sockets to help provide the necessary torque to deal with even the most stubborn fasteners. The 1/4-inch drive sockets have T15, T20, T25, T27, and T30 size heads while the 3/8-inch drive sockets have T40, T45, and T50 size heads. To keep them securely attached to ratchets, extension bars, and adapters, each socket features a ball detent recess on the drive end. Designed and constructed to meet or exceed ASME tool performance standards, these tools can stand up to the rigors of any professional workshop while being just as handy in the home mechanic's garage.
