M303.162 inset micrometer head — 50 mm range, large 29 mm thimble, carbide spindle

The M303.162 is an inset micrometer head designed for integration into jigs, fixtures and measuring stations where compact, repeatable linear measurement is required.

• 50 mm measuring range
• 29 mm large thimble
• Carbide spindle, 8 mm diameter
• Ratchet stop for constant force

Precision and readable performance for production use

This inset micrometer head delivers a 50 mm measuring range with a mechanical reading of 0.01 mm, offering a balance between reach and fine resolution that suits both workshop and bench‑level quality control. The carbide spindle provides superior wear resistance, so the measuring face retains form under frequent contact; combined with the plane‑parallel measuring faces, this reduces tilting and improves repeatability. Compliance with DIN 863 signals industry‑standard tolerances and makes the unit straightforward to specify in drawings and inspection plans.

Designed for integration and reliable handling

The unit’s large thimble (29 mm) improves legibility and handling when mounted in confined stations, while the 1 mm spindle pitch gives a predictable linear advance per revolution, helpful when setting stops or calibrating travel. A built‑in ratchet stop ensures consistent measuring force, limiting operator‑induced variation during contact. The compact inset layout simplifies installation into retaining frames or adaptor blocks and helps maintain alignment in repetitive measurement cycles.

Durable components and application suitability

Manufactured with an 8 mm spindle and a focus on robust contact geometry, this measuring head is suited to fixtures used in small‑batch production, gauge assemblies and toolroom jigs. The combination of a hard wearing spindle surface and analog reading makes the unit serviceable in environments where electronic outputs are unnecessary or where a classic mechanical indicator is preferred. Its features support repetitive inspection tasks and prolong service life under regular use.
