Professional 3/4-7/8" 12-point ratcheting box wrench with dual sizes, chrome finish, and military-grade specifications for high-performance fastening applications.
The Snap-on R2428C is a professional-grade 3/4–7/8" 12-Point SAE 0° Offset Ratcheting Box Wrench designed for demanding maintenance and repair applications. This versatile tool features dual sizes at each end, allowing technicians to work with multiple fastener sizes without changing tools. The wrench incorporates Snap-on's advanced spline wrenching technology, which has been specifically engineered to service high-tensile strength spline nuts and bolts with precision and reliability.
Crafted with chrome plating for superior rust resistance, this ratcheting box wrench complies with Military Spec. MS-33787 and MIL-W-8982, ensuring it meets the highest industry standards for quality and durability. The precise radial spline teeth engage fastener teeth over a wider contact area, effectively minimizing stress concentration and enabling the application of high torque loads while reducing the risk of damage to both the fastener and the tool itself. The 0° offset design provides optimal ergonomics and accessibility in tight working spaces.
With a total length of 9-1/4 inches and a head depth of 1/2 inch, this tool is ideal for professional technicians, fleet maintenance operations, and industrial maintenance environments. The 12-point configuration works effectively on both ordinary 6 and 12-point fasteners, offering versatility similar to Snap-on's renowned Flank Drive® wrenching system. Whether you're working in aviation, aerospace, oil and gas, or general industry applications, this ratcheting box wrench delivers the performance and reliability you demand.
