Gauge pin M323.J81 — single gauge pin, 19.81 mm diameter, 50 mm length (Metav IndustryLine)

The gauge pin M323.J81 is a workshop-grade precision pin intended for dimensional verification and end-measurement tasks in metalworking and quality control.

• Workshop-grade construction
• Diameter 19.81 mm with ±0.002 mm accuracy
• 50 mm overall length for stable probing
• Supplied in protective transport case

Precision that reduces inspection uncertainty

The M323.J81 is engineered for reliable, repeatable checks where tight tolerances matter. Its 19.81 mm nominal diameter combined with an accuracy of ±0.002 mm makes it suitable for high-resolution comparative measurements and go/no-go fits. In practice, this level of precision shortens inspection cycles and lowers the risk of false rejects by providing a clear quantitative reference for pass/fail decisions. The robust geometry ensures consistent contact conditions during probing, which supports process stability in production and workshop environments.

Durable materials for daily workshop use

Made from special steel, this single gauge pin resists wear and retains form under frequent use, so calibration intervals can be predictable and maintenance remains straightforward. The choice of material delivers a balance between hardness and surface finish that preserves measurement integrity even under repeated contact. Where traceability is required, the M323.J81 can be incorporated into a regular inspection routine as a stable reference artefact, supporting quality control workflows without introducing unnecessary handling complexity.

Practical design for effective handling and storage

At a 50 mm overall length the pin provides sufficient engagement depth while remaining compact for bench-top work and tool-room setups. The single-piece configuration minimises play between components, and delivery in a protective transport case reduces the chance of transit damage and contamination. This practical packaging supports safe storage and quick deployment at the inspection station, helping technicians maintain a tidy and efficient measuring environment.
