The DAA 1 Inch Box-End Wrench is a custom made, laser cut, stainless steel wrench. It is strong enough to last a lifetime and thin-walled enough to fit between any dies for easy access and adjustment. The multiple jaws allow the handle to be positioned in the most suitable angle for tightening up those hard to reach nuts. This tool is designed for use with 1" nuts and will not fit the 1-1/8" used on some dies. We recommend changing any larger die nuts to standard 1" nuts, which will allow you to use this one tool for all your dies, and give you more clearance and access on your tool head.FeaturesPrecision cut and engravedConstructed from stainless steelDesigned for 1" nuts
