Metav IndustryLine pin gauge M323.231 — single 2.31 mm, ±0.001 mm, 50 mm length

A single high-precision pin gauge in a compact format, intended for fine final-dimension checks and calibration tasks in precision workshops and small-part production.

• High-precision ±0.001 mm
• Diameter 2.31 mm ground to size
• Length 50 mm for deeper bores
• Workshop-specification special steel

Precision where end measurements matter

This compact gauge offers ±0.001 mm tolerance, making it suitable for demanding end-dimension checks and go/no-go verification of small bores. The ground 2.31 mm diameter provides a defined reference that reduces measurement uncertainty when compared with improvised gauges. The fine tolerance supports reproducible decisions during quality control and minimises costly rework by confirming conformity at the production stage.

Compact design for fine mechanical workflows

With a 50 mm shank, the gauge is tailored to access confined bores and recesses while remaining robust in handling. Classified in the micro range (max measuring range 10–100 mm), this format is ideal for watchmaking, precision engineering and instruments where short, rigid measuring elements reduce bending and operator-induced error. The compact geometry thus translates into reliable, repeatable checks on small components.

Material and durability for workshop use

Manufactured in special steel and finished for workshop conditions, the pin gauge resists wear under routine use while maintaining measurement integrity. The material selection and workshop-specification finishing ensure consistent surface condition and dimensional stability over repeated cycles, supporting steady inspection throughput and predictable maintenance intervals.

Practical benefits for quality workflows

Integrating this single pin gauge into routine inspections delivers a clear time advantage: quick physical comparison against hole diameters avoids lengthy set‑ups on larger fixtures. The gauge’s simplicity supports rapid decisions in incoming inspection, in-process checks and final acceptance, improving process flow and allowing experienced operators to concentrate on critical value-adding tasks.
