High precision where tolerances matter

The gauge pin offers a tolerance of ±0.001 mm, which places it in the high‑precision category for manual gauging tasks. Such fine specification reduces uncertainty when checking bore sizes, alignment seats or end dimensions, because the pin represents a defined reference diameter for fit and clearance assessments. The tight tolerance is especially useful in assembly control and incoming inspection where small deviations can have large downstream effects. By using a dedicated reference pin rather than approximating with improvised tools, measurement consistency and process reliability are improved.

Durable workshop design for repeated handling

Manufactured from special steel, the pin is designed for frequent use in industrial workshops. The material choice provides the mechanical resilience required for repeated insertion checks and minimises wear on the reference surface, prolonging useful life. The 50 mm length offers sufficient engagement for stable positioning without excess bulk, aiding handling and repeatable seating during checks. Supplied in a protective case, the component is protected during transport and storage, which helps retain its dimensional integrity between uses.

Practical integration and traceability in quality routines

This single‑piece gauge pin is ideal for incorporation into standard quality procedures and manual test benches as a simple, reliable reference. The compact form factor supports quick changeover and straightforward storage in tool sets. Identification via article number and barcode facilitates traceability within inspection records and stock lists, supporting audit requirements and component lifecycle management. Metav IndustryLine’s offering benefits from the company’s quality filter in Emmerich, ensuring consistent supply and documentation for professional workshops and production environments.
