Metav IndustryLine M307.044 – Micrometer for wheel hubs, 25–50 mm, 0.01 mm

Metav IndustryLine M307.044 is a compact micrometer designed for accurate measurement of wheel hubs and bore shoulders in workshop environments

• Accurate to ±0.006 mm
• Ratchet stop for constant measuring force
• Flat anvil suited to hub shoulders
• Supplied in a protective case

Precise, repeatable readings for critical hub geometry

The gauge offers a 25–50 mm measuring range with a standard reading step of 0.01 mm and a verified accuracy of ±0.006 mm, delivering reliable results where fit and concentricity matter. The finely pitched 0.5 mm spindle and matt‑chromed measuring drum combine to give a tactile, low‑play feel; paired with the ratchet stop, this ensures reproducible contact force and reduces variability from manual pressure. For inspections of bearing seats and bore shoulders, this level of repeatability reduces rework cycles and supports consistent assembly quality.

Robust design that suits everyday workshop use

Built with a painted frame and a matt‑chromed measuring drum, the instrument withstands typical shop handling while remaining comfortable to operate. The flat anvil profile is optimised for contacting hub shoulders, and the measuring faces, sized at 6.5 mm, concentrate contact area where it is needed for axial stability. At approximately 0.3 kg, the device is light enough for single‑handed use yet rigid enough to avoid flex under normal measurement forces. Supplied in a protective case, the micrometer is protected in transport and storage.

Clear technical advantages that speed inspection

The combination of fine spindle pitch and ratchet mechanism makes fine adjustments straightforward and reduces measurement scatter during repetitive checks. The device’s resolution and stated deviation support its use for workshop and production quality control tasks where tolerances are tight but measurement throughput remains important. The compact format classified in the micro micrometer class (ideal for short‑reach, high‑precision tasks) facilitates quick checks on smaller components without sacrificing accuracy.

Application focus: where this micrometer adds value

Intended primarily for measurements of wheel hubs and bore shoulders, the micrometer is also suitable for short‑range internal checks and specific component seating measurements that require a flat contact surface. As a practical instrument for maintenance bays and production lines, it bridges bench metrology and on‑machine control: fast enough for routine checks, accurate enough for verification tasks that feed into assembly decisions. Metav’s selection ensures compatibility with workshop workflows and a straightforward supply chain from Emmerich.
