Abstract
Device having movable jaws for gripping the shank of a pin or bolt is provided with ridges or grooves on the jaws which mate with corresponding ridges or grooves on the shank. The jaws are mounted to slide toward and away from each other and this sliding movement is induced by linkage pivotally connected to the jaws. An abutment is provided for limiting the movement of one of the jaws so that actuation of the linkage causes movement of said one jaw until it strikes the abutment followed by movement of the other jaw.
