Three‑point internal micrometer M836.712 — self‑centring analogue gauge (35–40 mm)

The three‑point internal micrometer M836.712 is an analogue, self‑centring instrument designed for precise internal diameter measurement in fine mechanical and toolmaking environments.

• Self‑centring three‑point contact
• High precision: 0.005 mm accuracy
• Analogue readout with defined measuring faces

Precision where small dimensions decide

The instrument delivers a measured accuracy of 0.005 mm, making it suitable for demanding inspection tasks where component interchangeability matters. The analogue mechanical mechanism provides tactile feedback during measurement, which helps experienced operators judge correct seating and contact. This combination of fine resolution and mechanical feel supports consistent quality checks on small bores without relying on electronic systems.

Stable centring for repeatable bore readings

The three‑point contact geometry is self‑centring, so the contact points automatically align with the internal axis of the bore. That geometry reduces eccentricity errors and improves repeatability, particularly in cylindrical housings and precision fittings. For processes that require repeated measurements across a batch, the self‑centring action minimises operator influence and shortens inspection time per part.

Compact micro range with clear measuring faces

Designed for the 35–40 mm span, this instrument falls within the micro range, which is ideal for fine mechanical assemblies and small tooling components. The device includes defined measuring faces that ensure secure contact and reliable readings even in shallow bores. The compact design balances reach and stiffness, enabling stable two‑hand or bench measurements while maintaining ease of handling in workshop environments.

Integration into workshop routines and supply confidence

As a Metav IndustryLine product, the gauge fits into a supply chain geared to workshops and small series manufacturers: robust mechanical design, straightforward handling and compatibility with traditional inspection workflows. The instrument supports standard measuring procedures and can be paired with existing inspection jigs or borescope checks to form a dependable quality control step without introducing complex electronics.
