• Diameter Ø 2.21 mm, ground finish
• Length 50 mm for fixture and gauge checking
• Workshop version for durable daily use

Precision that makes inspection faster and safer

The compact test pin delivers measurable gains in process reliability thanks to its ±0.001 mm manufacturing tolerance. This level of accuracy translates into fewer ambiguous fits when checking bores, pins and alignment seats, reducing rework and inspection time. Ground to a consistent Ø 2.21 mm, the pin offers a defined reference diameter for plug‑type checks and end‑measurement tasks; the small footprint and consistent roundness are ideal for tight tolerances and repeatable comparisons.

Robust design for daily workshop demands

Built as a workshop version, the test pin uses special steel to combine wear resistance with dimensional stability at the contact surfaces. The 50 mm length provides sufficient reach for a wide range of fixtures while remaining easy to handle during batch checks. The single‑piece delivery format is convenient for targeted replacements or stocking as reference tools in inspection kits. The result is a tool that resists routine abrasion and preserves accuracy over many inspection cycles.

Integrates into inspection processes with minimal overhead

Designed for pragmatic use in industrial metrology, the pin slots into existing gauge‑based routines without the need for complex calibration steps. Its clear numeric specification — Ø 2.21 mm, 50 mm length, ±0.001 mm tolerance — enables straightforward documentation in inspection plans and process sheets. Where traceable calibration is required, Metav Werkzeuge can advise on calibration options and system integration to maintain measurement integrity across production and QA workflows.
