M309.023 — Three‑point outside micrometer, 35–50 mm, carbide faces (Metav IndustryLine)

The M309.023 is a three‑point outside micrometer designed for precise measurement of triangular and multi‑sided workpieces in machine shops and inspection benches.

• Three-point measuring for polygonal parts
• Carbide measuring faces for long service life
• 35–50 mm measuring range
• Ratchet stop for consistent measuring force

Consistent results for polygonal components

The three‑point measuring principle delivers a secure contact on three, and by extension five, flat surfaces, reducing the influence of edge irregularities and enabling repeatable results on polygonal parts. The instrument’s carbide measuring faces resist wear and retain form under repeated use, which helps maintain measurement traceability across production batches. A calibrated ratchet stop ensures a defined measuring force, preventing over‑tightening and keeping operator‑induced variation to a minimum.

Precision and reading clarity for workshop use

This analogue micrometer provides a fine reading of 0.01 mm combined with a verified accuracy of 0.006 mm, making it suitable for routine dimensional checks where sub‑hundredth‑millimetre resolution is required. The matt‑chromed measuring drum improves legibility under workshop lighting while the painted frame reduces glare. Together, these features contribute to faster, more reliable inspection cycles and a reduced rate of rework.

Built for the shop floor with practical delivery

Constructed with a robust frame and finished measuring surfaces, the device includes a ratchet for uniform contact pressure and is delivered in a transport case to protect the instrument during storage and transit. The tool is intended for measuring triangular and pentagonal workpieces and comes with a setting gauge (setting size: 335 mm) for quick verification and adjustment. The compact 35–50 mm range is particularly well suited to fine mechanical tasks and precision workshop applications where space and stiffness are decisive.
