Are you tired of not having the right size open wrench? This WORKPRO 4-Piece Adjustable Wrench Set will ensure you have the right size wrench every time. Adjustable wrenches like these are open-end wrenches that feature movable jaws, allowing them to be used with different sizes of fastener heads, rather than needing a conventional fixed spanner size for each fastener head size. Using the knurl adjusting screw to adjust the jaws to fit the fasteners, wrenches like these (sometimes referred to as crescent or adjustable spanner wrenches) can be used to loosen or tighten nuts and bolts easily. Each adjustable wrench is constructed of chrome vanadium and feature an anti-slip handle. They each have an extra wide opening capacity, and include a precise scale etched on the side of the jaw. Purchase your set today, and ready yourself for tomorrow’s repair projects.
