A clamp assembly for securing small parts is described herein. In some embodiments, the clamp assembly comprises a free jaw and a fixed jaw configured to secure a part positioned at a proximal end of the clamp assembly between a free jaw pad and a fixed jaw pad. The free jaw is configured to rotate at least about a size pin positioned at a distal end of the fixed jaw opposite the part. The free jaw is rotated by a tightening feature positioned proximate the free jaw pad and fixed jaw pad at the proximal end. As the tightening feature is actuated, the free jaw pad rotates toward the fixed jaw pad securing the part therebetween when the fixed jaw pad and the free jaw pad are substantially parallel.
