M836.713 three-point internal micrometer — self-centring, 40–50 mm

The M836.713 three-point internal micrometer is an analogue inside micrometer designed for accurate bore measurements in quality control and workshop inspection.

• Self-centring three-point contact
• Measuring range 40–50 mm
• Resolution 0.005 mm on vernier
• Supplied in protective case

Reliable precision for internal diameters

The three-point contact system provides a consistent datum by aligning all contact points automatically, which reduces operator-induced error and shortens setup time. With an indicated accuracy of ±0.006 mm and a vernier readability of 0.005 mm, the instrument is suited to inspection tasks where repeatability is critical. The analogue design eliminates reliance on electronics, offering a stable, maintenance-light option for standard inspection benches and machine shops.

Faster measuring cycles and lower rework

Because the device centres itself on the bore, measurement cycles become more efficient and less dependent on manual alignment. The self-centring feature yields reproducible results across multiple operators, cutting down on scrap and rework. Hardened measuring faces resist wear during repeated contact and preserve dimensional integrity over long service intervals, supporting consistent process control in production environments.

Robust delivery and workshop compatibility

The micrometer arrives in a protective case suitable for safe transport and storage, which helps maintain calibration between uses. The analogue vernier scale is immediately readable to 0.005 mm and requires no batteries, making the tool dependable in harsh or low-power settings. For traceable inspection routines, the instrument’s specifications and serial details are documented, facilitating integration into existing quality records and routine checks.
