The Proto B328977 Tether-Ready combination wrench features a 12-point box end with the TorquePlus™ system for superior fastener engagement, fine indexing, and improved speed and access. The satin finish provides corrosion resistance and a slip-resistant grip, while the Anti-Slip Design (ASD) open end reduces fastener rounding on compatible sizes.
Designed to fit 4, 6, and 12-point fasteners, this 11/16-inch wrench is ideal for industrial, MRO, and professional applications where tool retention and durability are critical. Tether-ready design supports dropped-object prevention programs in elevated or safety-sensitive work environments.
