Build your own pipe wrench by pairing a handle and jaw to grip most round surfaces, even highly polished objects. Push down on the wrench and pull the handle toward youâ€”the jaws will tighten around the workpiece.

Tighten or loosen nuts and bolts without damaging the finish. The tough steel core of the socket withstands the high torque of impact tools, but the insert and outer sleeve are made of plastic, which wonâ€™t scratch chrome plating and other coatings. Remove the outer sleeve for a thinner profile when working in tight spaces. Each size is a different color for easy identification.
