Three‑point internal micrometer M836.702 — Self‑centring design, 0.005 mm accuracy (Metav IndustryLine)

The Three‑point internal micrometer M836.702 is a compact precision instrument for repeatable measurement of small internal diameters in fine mechanical and machining environments.

• Self‑centring three‑point design
• High accuracy 0.005 mm
• Hardened measuring faces

Reduce rework with measurable accuracy

The instrument delivers a certified mechanical accuracy of 0.005 mm, which translates into tighter tolerances during assembly and less rework on precision parts. By converting raw resolution into a clear production benefit, the micrometer shortens inspection loops and supports quality gates in machining workflows. The analog nonius readout provides a tactile feedback loop that experienced inspectors value for immediate verification, while the robust mechanical design maintains stable results under repeated use.

Secure concentric measurements in small bores

Designed as a three‑point, self‑centring device, the micrometer seats itself within the bore to establish a reproducible datum across measurements. This geometry reduces operator‑induced eccentricity and improves repeatability when inspecting small diameters in components such as valve seats, bushings or precision housings. With a measuring range of 4.5–5.5 mm and hardened measuring faces, the instrument is optimised for fine internal diameters where consistent contact geometry and surface resistance to wear are essential for long service life.

Robust handling for everyday workshop use

The mechanical construction emphasises longevity and simple maintenance: solid moving parts, a reliable spindle mechanism and clearly engraved scales make the tool suitable for daily use in both inspection benches and production cells. As an analogue micrometer with precise mechanical engineering, it performs without requiring batteries or electronics, which reduces maintenance points and keeps the inspection process straightforward. The combination of self‑centring functionality and hardened contact surfaces offers a practical, low‑complexity solution for high‑volume verification routines.
