With its contoured, rubber-cushioned handle to provide a comfortable grip and its cam-action jaw mechanism to increase grip as torque is applied, the lightweight, self-adjusting Power-Grip Hex Nut Wrench enables one with limited hand or arm strength to loosen/tighten hex nuts without having to change wrenches or hands. The 8-inch wrench accommodates 3/8- to 3/4-inch nuts, while the 10-inch tool handles 1/2- to 15/16-inch nuts, the specially designed jaws self-adjusting to any size within its capacity while preventing slippage. Other features include fast ratcheting action and a thumb-actuated jaw release.
