M307.031 — Micrometer, 0–25 mm, 0.01 mm resolution, 100 mm frame depth (Metav IndustryLine)

M307.031 is a precision micrometer screw gauge designed for fine mechanical and workshop use, offering a deep frame for measurements in recesses and compact workpieces.

• Large 100 mm frame depth
• Measuring range 0–25 mm
• Resolution 0.01 mm
• Ratchet spindle for consistent force

Precision and repeatability where it counts

The M307.031 micrometer combines a fine mechanical reading with a 0.01 mm resolution, delivering industrially relevant repeatability for routine quality checks. The integrated ratchet stop ensures a consistent contact force, reducing operator‑induced variation for comparable results across batches. With a spindle pitch of 0.5 mm the instrument permits controlled approach and fine adjustment; this spindle geometry supports stable readings and straightforward calibration routines. Compliance with DIN 863 provides an established reference for tolerances and construction, making the device suitable for everyday workshop metrology and production sampling.

Reach into recesses and measure compact parts reliably

A 100 mm frame depth gives this gauge the reach required to access recessed features, shoulders and step geometries that standard micrometers cannot easily serve. Classified in the micro‑range for compact measuring tools, it is particularly useful in precision engineering, toolmaking and small‑part inspection where a short measuring range and high stiffness are preferred. The hardened measuring faces and matt chrome‑plated measuring drum maintain contact integrity and reduce surface wear, while the lacquered frame resists workshop abrasion — a blend that preserves accuracy over prolonged use and frequent handling.

Robust construction and workshop suitability with traceable quality

Built for everyday industrial use, the instrument pairs practical durability with traceable standards. The hardened measuring faces support wear resistance and stable zero‑points, and the matt‑finished drum improves legibility under workshop lighting. The design emphasises straightforward, maintenance‑friendly operation; routine checks and recalibration follow common shop procedures. Metav IndustryLine supplies this micrometer as part of a wider precision portfolio that supports suppliers and workshops with central stock and quality assurance — a dependable source for scalable measurement equipment.
