Tronic 10 Inch Adjustable Wrench

This tool can be used to loosen or tighten a nut or bolt. It has a jaw the part where the nut or bolt fits, which is of adjustable size. The adjustable wrench works by turning a screw, which is usually located at the bottom of the head. While ordinary wrenches can only be used on a particular size nut, an adjustable wrench can be used on a much wider variety of nut sizes.
