Professional-grade 3/8–7/16" 12-Point SAE ratcheting box wrench with precision spline teeth, chrome finish, military-spec compliance, and dual-size versatility for demanding industrial maintenance applications.
The Snap-on 3/8–7/16" 12-Point SAE 0° Offset Ratcheting Box Wrench (Model R1214C) is a professional-grade precision tool engineered for high-performance fastening applications. This dual-size wrench features spline wrenching technology specifically developed to service high-tensile strength spline nuts and bolts with exceptional precision and reliability. The precise radial spline teeth engage fastener teeth over a wider area, effectively minimizing stress concentration and enabling the application of high torque while reducing the risk of damage to both the fastener and the tool itself.
Crafted with a durable chrome finish that complies with Military Specification MS-33787 and MIL-W-8982, this ratcheting box wrench delivers superior rust resistance and longevity in demanding industrial environments. The 0° offset design provides optimal ergonomics and accessibility in confined spaces, while the 12-point configuration ensures versatility for use on ordinary 6 and 12-point fasteners, offering an advantage similar to the renowned Snap-on Flank Drive wrenching system. With a total length of 5-1/2 inches and head depth of 3/8 inch, this tool is engineered for professional technicians in aviation, aerospace, military, defense, oil and gas, power generation, and heavy-duty fleet maintenance industries.
The dual-size design at each end allows for exceptional versatility, enabling technicians to handle multiple fastener sizes with a single tool. Whether performing critical maintenance on aircraft, military equipment, or industrial machinery, this Snap-on ratcheting box wrench delivers the precision, durability, and reliability demanded by professional maintenance operations worldwide.
