St. Mary Rotary “V” Block Gage
The precision St. Mary Rotary “V” Block Gage makes measuring concentricity characteristics on cold headed parts faster. easier, and more precise than other similar devices.
Geometric tolerancing measurement requirements are becoming more common on fasteners and cold formed specials.
