The Channellock Griplock Pliers have an ergonomically designed offset head which provides high leverage. A special jaw design allows them to grip down on many shapes for added versatility. These pliers are built to last with a Permalock fastener to eliminate nut and bolt failure and laser-hardened teeth to provide a better, longer lasting grip. They are made in the USA and forged from high carbon U.S. steel specially coated for ultimate rust prevention.
