This 255-piece fractional intermediate set from Wright Tool covers all four drive sizes — 1/4", 3/8", 1/2", and 3/4" — in SAE, a strong middle ground for a shop that has outgrown a basic kit but doesn't need a full mega set. At about 155 pounds, it delivers broad fractional coverage in a manageable footprint, with every tool forged and machined in the USA.
Wright Drive technology distributes contact over a larger portion of the fastener for better torque and longer tool life, and WrightGrip 2.0 handles rounded or damaged heads that trip up ordinary sockets. The set conforms to ASME B107 series standards and carries a limited lifetime warranty.
With four drives on hand, it suits mechanics and maintenance technicians building comprehensive SAE coverage for automotive, equipment, and general repair across fleet and industrial settings. Tools only — pair it with a size-matched 46" Wright top chest or roller cabinet to keep everything organized and mobile.
