Taft-Peirce Metrology Company

Taft-Peirce Metrology designs and manufactures precision workholding and inspection tools trusted by leading manufacturers and agencies—including teams at the U.S. Department of Defense, Boeing, Northrop Grumman, Tesla, SpaceX, and more. Rooted in American toolmaking, we build products that deliver stable flatness, squareness, and parallelism under real shop conditions. Core specialties include inspection-grade angle plates (ribbed/solid), V-blocks & clamps, magnetic chucks, sine plates, parallels & matched sets, master squares, surface gages, and related fixturing for grinding, milling, EDM, CMM, and bench inspection. Components are produced from carefully selected, stress-relieved cast iron and hardened, ground steels, then precision ground and lapped to tight, repeatable tolerances. Every design emphasizes thermal stability, rigidity, and long service life to help manufacturers set, hold, and verify critical geometry with confidence. In addition to our catalog, we offer made-to-order configurations—special sizes, hole patterns, and auxiliary features—to fit unique setups. Industries served include aerospace, defense, medical device, automotive, and high-precision contract manufacturing. Our mission is simple: build metrology and workholding solutions that earn their place on the surface plate—every day.
