This 368-piece fractional master maintenance set from Wright Tool delivers deep SAE coverage across three drive sizes: 1/4", 3/8", and 1/2". At 135 pounds, it's built for maintenance departments and service shops that need one comprehensive fractional set on the floor instead of a patchwork of smaller kits. Every socket, ratchet, and accessory is forged and machined in the USA for precise fastener fit and long service life.
Each tool uses Wright's patented Wright Drive technology, which spreads contact across a larger surface of the fastener for better torque transfer and less rounding. WrightGrip 2.0 grips worn and damaged fasteners that standard tools slip on. The set meets ASME B107 series standards and carries Wright's limited lifetime warranty.
The three-drive fractional range handles light assembly with 1/4" drive up to heavy equipment work with 1/2" drive — a fit for fleet maintenance, industrial MRO, and plant service teams working primarily in SAE sizes. This is a tools-only set; pair it with a size-matched 46" Wright top chest or roller cabinet for a complete rolling workstation.
