Professional-grade 3/8" SAE ratcheting box wrench with Flank Drive® technology, 12-point design, 0° offset, and up to 80-tooth ratcheting mechanism for maximum torque and accessibility in confined spaces.
The Snap-on 3/8" 12-Point SAE Flank Drive® High-Performance Combination Ratcheting Box Wrench (Model XDLR12A) is engineered for professional technicians who demand superior performance and reliability. This innovative ratcheting wrench combines extended-length handle design with 0° offset positioning to deliver exceptional leverage and maximum torque capacity for breaking loose the most difficult fasteners. The unidirectional ratcheting gear system utilizes cutting-edge Snap-on® technology to provide more power in less lateral space, making it ideal for accessing and removing stubborn fasteners in confined working areas.
Constructed from precision-forged special alloy steel and heat-treated for optimum strength and durability, this wrench features up to 80 ratcheting teeth in conjunction with an 8-tooth pawl mechanism that minimizes the swing arc required to move fasteners in restricted spaces. The chrome-finished 12-point box head generates up to 15-20% more turning power than conventional wrenches while significantly minimizing the risk of tool or fastener damage. With its 10-3/32" total length and carefully engineered dimensions, this wrench delivers professional-grade performance across aviation, aerospace, military, defense, oil and gas, power generation, railroad, and general industrial applications.
The Flank Drive® wrenching system represents the pinnacle of wrench engineering, combining innovative gear design with superior material science to create a tool that performs reliably under the most demanding conditions. Whether you're working in tight engine compartments, confined machinery spaces, or challenging field environments, this ratcheting box wrench provides the power, precision, and durability that professional technicians expect from Snap-on tools.
