The Proto J1215MHASD 15mm combination wrench features a satin finish for corrosion resistance and a slip-resistant grip, a 6-point box end with TorquePlus™ system for maximum fastener contact to prevent rounding, and a patented Anti-Slip Design (ASD) open end with locking grooves and arched surfaces that spread contact forces away from fastener corners.
Engineered for professional MRO and industrial applications, the ASD open end keeps loads off fastener corners during turning, significantly reducing the risk of fastener damage. The 6-point box end ensures a secure, high-torque fit on metric fasteners, making this wrench a reliable choice for demanding shop and field environments.
