PROTO® EXTRA THIN SATIN OPEN-END WRENCH - 1/2" X 9/16"

Satin finish provides corrosion resistance and a slip resistant grip. Ultra-thin profile and long handle produce improved access to hard-to-reach fasteners. Use when high leverage or distance from a hot assembly is required. Opening is designed to cover tappets, screws and lock nuts without excessive overhang which improves access.
