PROTO® EXTRA THIN SATIN OPEN-END WRENCH - 9/16" X 5/8"

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.
