Professional 13-15mm metric box wrench with Flank Drive technology, 10° offset handle, stainless steel construction, and integrated safety lanyard attachment for working at height.
The Tools@Height 13-15 mm 12-Point Metric Flank Drive® 10° Offset Box Wrench (Model THXBM1315A) is an innovative professional-grade tool designed specifically for working at height and in confined spaces. This wrench features Snap-on's proprietary Tools@Height System that tethers each tool with its own lanyard, effectively minimizing tool exchanges and significantly reducing the likelihood of dangerous drops. The engineering incorporates attachment points that do not interfere with the tool's functionality, ensuring optimal performance and full utilization of the handle for maximum leverage.
Manufactured from high-quality polished stainless steel, this wrench delivers superior flexibility and exceptional shock-absorbing qualities compared to welded alternatives. The wrench features a 10° offset handle design that provides maximum knuckle clearance and improved access in tight spaces, making it ideal for complex mechanical work. The Flank Drive® wrenching system on the box-end delivers up to 15-20% more turning power while reducing the risk of tool and fastener damage, ensuring reliable performance on every application.
The wrench is finished with tough, durable nickel-chrome plating that produces a mirror-like finish, providing superior corrosion protection and easy maintenance. With dimensions of 241mm in length and weighing only 0.32 lbs (0.15 kg), this tool is sized for optimum comfort and balance in your hand. The lanyard attachment point slides out of the way along the wrench's handle to provide complete functionality without obstruction. This professional tool is ideal for aviation, aerospace, military, defense, oil and gas, power generation, railroad, and general industrial applications.
