The Proto B329380 Tether-Ready combination wrench features a satin finish for corrosion resistance and a slip-resistant grip, with a 12-point box end that allows fine indexing to improve speed and access in tight spaces. The box end incorporates the TorquePlus™ system and fits 4, 6, and 12-point fasteners for versatile use.
The open end features an Anti-Slip Design (ASD) that grips fastener flats to reduce rounding, making it ideal for MRO, industrial, and professional trade applications. This wrench is built tether-ready for use in elevated or drop-hazard environments.
