The Powerbuilt 200 Piece Master Mechanic's Service Tool Set offers a broad tool selection and the coverage needed for the majority of service jobs in the garage, house or on the jobsite. It includes the most popular ¼", 3/8" and 1/2" inch drive sockets in shallow and deep styles in both SAE and metric sizes. Included in this set is our 90-tooth sealed head pro grade ratchets that require just a 4-degree swing to engage, making them ideal for the tightest spaces. Built from strong chrome vanadium steel with a beautiful mirror finish, the 90-tooth ratchet features an ergonomic full-length handle, molded finger grooves, and a fully sealed head that keeps lubricant in, and debris out, for longer service intervals. Strong as well as beautiful, Powerbuilt sockets are constructed of premium chrome vanadium steel and feature stamped high-visibility size markings, our innovative Z-Drive design and precision chamfered openings make it easier to slide the sockets over fasteners, while the punched center holes add working space for taller nut and bolt stock. 200 Piece Master Mechanic's Service Tool Set
