General purpose tongue-and-groove pliers provide a wide jaw-capacity range to grip and turn pipes, fittings, fasteners, and other items in applications where insulated, non-sparking, or other special environment pliers aren't required. Also known as multigrips and groove-joint pliers, they have an adjustable pivot point for moving their lower jaw up or down a grooved channel to set the distance between the jaws. The jaws lock into place at the desired setting, remain parallel to maintain grip, and are angled from the handles to increase leverage.
