Gauge pin M323.189 — 1.89 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

A gauge pin M323.189 engineered for precise end‑measurement and verification tasks in workshop inspection and fixture‑setting applications.

• Submicron tolerance ±0.001 mm
• Diameter 1.89 mm for fine gauging
• 50 mm length for end‑dimension checks
• Workshop design with protective transport case

Consistent, measurable precision for quality control

The core strength of this gauge pin lies in its ±0.001 mm tolerance, which corresponds to 1 µm of dimensional control. That level of precision reduces uncertainty in end‑dimension verification and supports repeatable go/no‑go assessments during in‑process inspection. Where measurement drift or manual variation can affect outcomes, the tight tolerance provides a reliable, objective reference for setting small‑bore gauges, aligning fixtures or verifying bore sizes. The result is faster decision‑making on the shop floor and fewer downstream reworks.

Durable workshop construction that simplifies handling

Manufactured from special steel and specified as a workshop version, the component balances wear resistance with everyday usability. The 50 mm length gives sufficient engagement for end‑measurement without compromising handling or storage, while the 1.89 mm diameter suits fine bore and pin‑gage applications. Delivered in a protective transport case, the item is safeguarded against knocks and contamination during transit and storage, which preserves surface finish and dimensional integrity. This practical packaging supports a longer service life and consistent measurement results.

Practical use cases and integration into inspection routines

The pin is ideal as a reference for small‑bore checking, fixture alignment and calibration tasks in metalworking and precision assembly. Known as M323.189 in the Metav IndustryLine range, it slots neatly into established inspection workflows and complements micrometre and gauge systems by providing a compact, high‑accuracy datum. Where repeatability and traceability are required, the stake‑out nature of this component reduces operator variability and streamlines measurement steps, enabling technicians to prioritise throughput without compromising quality.
