Made of sturdy stainless steel, this caliper features 0.001" graduations (0.100" per revolution). A knob at the bottom of the dial face can be loosened to allow the face to turn and thereby 'zero' the caliper while the knob at the top of the caliper can be tightened to lock down a measurement. This precise measuring tool is the perfect addition to every gunsmiths assortment of tools. Also includes a hard shell case for storage.
