Wiha Tools Adjustable Wrench Sets, Alloy Steel, Natural, Jaw Capacity 1", 1-1/2", Yes, Quick Adjust

Insulated adjustable wrench sets come with coated handles to protect from electric shock and reduce the possibility of electrical arcing caused by a short circuit from a noninsulated handle. 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. Wrench sets provide multiple jaw capacities and lengths so they can be used with a range of fasteners. They have 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.
