The Proto B329756 1-inch combination wrench features a 12-point satin finish that provides corrosion resistance and a slip-resistant grip. The 12-point box end allows for fine indexing to improve speed and access in tight spaces, and incorporates the TorquePlus™ system for superior torque transfer. Fits 4, 6, and 12-point fasteners.
The open end features Proto's Anti-Slip Design (ASD) for added control and safety during use. This wrench is also Tether-Ready (-TT), making it suitable for use in elevated or controlled work environments where dropped-tool prevention is required.
