Gauge pin M323.721 — single precision gauge pin, ø 7.21 mm, tolerance ±0.001 mm (Metav IndustryLine)

The gauge pin M323.721 is a single, precision test pin designed for end‑size verification and assembly checks in workshop and production environments.

• Workshop version for daily use
• Diameter 7.21 mm for end‑size checks
• Tolerance ±0.001 mm for high precision
• Length 50 mm for stable insertion depth

Precision that stabilises production quality

The gauge pin is manufactured to a tight tolerance of ±0.001 mm, ensuring consistent pass/fail decisions when checking end dimensions. Such fine repeatability reduces rework and scrap by making dimensional checks decisive rather than suggestive. With a nominal diameter of 7.21 mm and a calibrated profile, the component is suitable for use as a reference pin in go/no‑go fixtures and bench checks. The small mass (0.02 kg) and compact geometry cut cycle time for manual checks while keeping handling safe and straightforward.

Robust design for everyday workshop demands

Built as a workshop version, the pin combines a hard, wear‑resistant special steel body with geometry optimised for repeated insertion. The 50 mm length gives enough engagement to avoid wobble while maintaining accessibility in confined assemblies. The material choice provides a balance between surface hardness and machinability, yielding long service life under regular use. This robust construction supports reliable measurements over time, reducing the need for frequent replacement and supporting continuous production flows.

Integrates smoothly into quality workflows

Use the pin for final dimensional verification, fixture validation and as a reference in assembly jigs where a defined end measurement is required. The clear specification (ø 7.21 mm, ±0.001 mm, 50 mm) simplifies documentation and traceability when incorporated into inspection protocols. For workshops aiming to formalise quality control steps, the pin is an efficient tool for transferring tolerances from drawings into practical checks. Its precise dimensioning helps to avoid ambiguous assessments and to document conformity with internal tolerance plans.
