M303.170 micrometer head — 0–25 mm range, 0.002 mm fine reading (Metav IndustryLine)

The M303.170 is a compact inset micrometer head designed for fine mechanical measurement tasks, offering a 0–25 mm measuring range and a high-resolution 0.002 mm reading for repeatable dimensional checks.

• 0–25 mm measuring range
• 0.002 mm fine reading
• Carbide spindle, 8 mm diameter
• 49 mm large drum for clear reading

Precision that reduces rework and inspection time

The micrometer head delivers a 0.002 mm reading resolution and a 1 mm spindle pitch, translating measurement movement directly into highly reproducible values; this reduces uncertainty in incoming inspection and shortens rework loops. Conformity with DIN 863 gives a familiar reference for quality systems and simplifies documentation. The combination of a fine graduation (100 divisions on the drum) and a substantial drum diameter supports quick, unambiguous readings during repetitive checks.

Robust spindle and clear visual feedback for confident handling

A carbide spindle ensures long-term wear resistance where contact accuracy matters most; paired with flat-parallel measuring faces, the head maintains geometric integrity over extended use. The 49 mm large drum improves legibility, which eases operator work and lowers the risk of misreading. The spindle diameter of 8 mm provides a stable bearing surface that contributes to low runout and steady contact force during measurement cycles.

Simple integration into fixtures and standardised workflows

Designed as an inset measuring unit, the head is ready for mounting into gauges, fixtures or custom assemblies; the compact dimensions correspond to the Mikro class for small-range metrology (0–25 mm). The analog design with 100 drum divisions is ideal where mechanical simplicity and immediate visual verification are preferred over electronic output. For organisations requiring traceable processes, the reference to DIN 863 streamlines compatibility with calibration schedules and inspection plans.

Ideal uses and practical advantages in the workshop

This micrometer head is suited to fine mechanical workshops, toolrooms and assembly lines that demand repeatable small-range measurements — from small components to fine threads and turned features. The sturdy spindle and clear drum marking deliver both tactile reliability and visual certainty, helping to prevent measurement drift and supporting faster inspection cycles. Its compact inset form factor allows neat integration into bespoke fixtures without occupying excess space.
