Adjustable wrenches turn bolts, nuts, and other fasteners for installation (tightening) or removal (loosening). They have adjustable jaws that provide a tight grip on a variety of fastener sizes so that multiple wrenches are not required for different size fasteners. These wrenches allow access to the fastener from the top and side compared to box wrenches that can only access a fastener from the top. Wrench sets provide multiple jaw capacities and lengths so they can be used with a range of fasteners.
Insulated Adjustable Wrenches
These insulated adjustable wrenches have coated handles to protect from electric shock and reduce the possibility of electrical arcing caused by a short circuit from a noninsulated handle. They come with a screw mechanism located at the bottom of the head that adjusts the jaws for a tight grip on a variety of fastener sizes. The insulation cushions the handle to reduce fatigue and provides a more secure hand grip compared to bare metal handles.
