M323.331 gauge pin — 3.31 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

A M323.331 gauge pin designed as a single test pin for precise end‑measure and plug‑gauge checks in workshop and inspection environments.

• Diameter 3.31 mm with ±0.001 mm tolerance
• 50 mm measuring length for end‑measure checks
• Workshop execution with special steel construction
• Delivered in protective transport box

Consistent reference dimensions for reliable inspections

The gauge pin offers a nominal diameter of 3.31 mm with a tolerance of ±0.001 mm, delivering the dimensional certainty required for repeatable go/no‑go and reference checks. The 50 mm overall length provides sufficient engagement for many plug‑gauge and end‑measurement situations while remaining compact for quick handling. By using a single, calibrated reference dimension as the basis for inspection, process variability is reduced and measurement sequences become more predictable — beneficial for quality control tasks where comparability and traceability are essential. The combination of tight tolerance and compact form factor supports rapid validation of bores and mating features without complex fixturing.

Built for workshop handling and longevity

Manufactured in a workshop execution from special steel, this test pin stands up to frequent use in production and maintenance contexts. The material selection and finishing aim to maintain dimensional stability under normal handling and to resist surface damage during insertion and extraction. At just 0.006 kg, the pin is easy to position and exchange in inspection jigs, minimising operator effort while preserving measurement integrity. The robust construction translates into fewer replacements and lower lifecycle interruption, making it suitable for busy workshop benches and inspection stations where uptime and reliability matter.

Practical integration and clear identification

Supplied as a single test pin, the component is practical for immediate deployment in inspection routines or as a reference item within master sets. Delivery includes a protective box for transport, preventing incidental damage during storage and movement between workstations. Traceability is supported by identifiers such as the SKU and GTIN, enabling straightforward inventory management and documentation in inspection records. The compact form factor and standard nominal dimension make the pin compatible with common plug‑gauge fixtures and handheld checks; when reproducible reference measurements are needed, this component integrates easily into existing quality workflows.
