The Fowler High Precision 72-229-214-0 is a four-piece Swiss-style outside micrometer set covering a combined measuring range of 0 to 4 inches, designed for general purpose dimensional measurement in manufacturing, machining, and mechanical engineering applications. Each micrometer in the set features a Vernier scale with 0.0001" graduation intervals on a satin chrome finish for highly precise and repeatable readings. Hardened, precision-ground, and micro-lapped carbide measuring faces deliver exceptional accuracy, while the heat-insulated frame protects the operator and minimizes thermal expansion errors. The friction-style thimble with ratchet stop ensures consistent measuring force across multiple users, making this set a reliable tool for professional inspection environments.
Features
Vernier scale with 0.0001" graduation intervals on a satin chrome finish for microfine, precise readings
Carbide measuring faces that are hardened, precision-ground, and micro-lapped for long-term accuracy
0.00003" flatness and 0.00005" parallelism on 0 to 1" micrometers for exacting measurement standards
Friction-style thimble with ratchet stop applies constant, repeatable force for consistent results between operators
Suitable for one-handed operation; ratchet stop halts spindle rotation upon contact with the workpiece
Heat-insulated frame reduces temperature-related expansion or contraction and protects the operator's hands
Positive locking nut on the spindle locks measurements in place for accurate reading and recording
Zero adjustment on the sleeve ensures ongoing calibration accuracy
