Gauge pin M323.189 — single inspection pin, 1.89 mm, ±0.001 mm (Metav IndustryLine)

The gauge pin M323.189 is a precision inspection pin for end‑dimension verification and plug‑gauge tasks in workshop and production metrology.

• Single gauge pin 1.89 mm diameter
• High precision ±0.001 mm tolerance
• 50 mm hardened special‑steel length
• Supplied in protective transport case

Precise end‑dimension checks with measurable confidence

The compact inspection pin delivers a diameter of 1.89 mm with an exceptional tolerance of ±0.001 mm, enabling highly repeatable end‑measurements for go/no‑go checks and verification of mating bores. The extremely fine tolerance corresponds to one micrometre resolution in practical use, which reduces rework and speeds decision cycles on the shop floor. This level of precision is particularly valuable for small‑part production where component fit and assembly depend on consistent end‑dimensions.

Built for workshop use and frequent handling

Designed as a workshop edition, the pin is manufactured from special steel and finished to withstand repetitive insertion and inspection routines. With a 50 mm working length and a compact form factor, the pin balances accessibility and stiffness for reliable tactile feedback during manual checks. Delivery in a protective transport case ensures the measuring surface remains free from contamination and impact damage during storage or transit, preserving long‑term accuracy.

Integrates smoothly into measurement routines

The inspection pin supports straightforward integration into standard metrology setups and fixture‑based control points. Its single‑piece design simplifies handling and quick substitution in test benches or inspection gauges, while the precise nominal diameter provides a clear reference for comparative assessments. For production control, the pin is a pragmatic choice where fast, repeatable verification of bore sizing and end‑dimensions improves throughput and reduces measurement uncertainty.
