Mitutoyo 250-312 Micrometer Heads, Ratchet Stop, 0.0001" Resolution, 0-1" Range, +/-0.0001" Accuracy

PRECISION-BUILT FOR FIXTURE INTEGRATION. Designed for use in custom fixtures, jigs, and measurement setups, offering smooth spindle travel, a durable construction, and a clear 0.0001" graduation scale that supports tight-tolerance inspection and dimensional verification.

EASY-READ MECHANICAL DIGIT COUNTER. Built with a mechanical digit counter that displays spindle travel numerically, allowing fast, error-free reading of measurements without relying solely on the thimble scale, ideal for repetitive or production-line checks.

RATCHET-STOP FOR CONSISTENT FORCE. Equipped with a ratchet-stop thimble that applies uniform measuring pressure, ensuring repeatable, high-accuracy readings and preventing operator-induced variation when measuring delicate or precision-machined surfaces.

CARBIDE-TIPPED FLAT MEASURING FACE. Features a hardened, carbide-tipped flat spindle face that resists wear and maintains long-term accuracy, providing stable, reliable contact surfaces for consistent measurement performance in demanding shop environments.
