Gauge pin M323.431 — Precision test pin, 4.31 mm ±0.001 mm, 50 mm | Metav IndustryLine

A gauge pin M323.431 for precise end‑measure and go/no‑go inspections in workshop and inspection environments

• Workshop version for everyday use
• 4.31 mm diameter with ±0.001 mm accuracy
• 50 mm length, special‑steel construction
• Delivered in protective transport box

Consistent, traceable precision for final dimension checks

The ±0.001 mm tolerance places this instrument in the high‑precision class for small‑diameter gauges, making it suitable as a reference for critical fits and end‑measure verifications. By using a finely manufactured 4.31 mm test pin, measurement uncertainty is reduced during pass/fail checks and gauge comparisons, which supports faster decision‑making on the shop floor and in the quality department. The pin’s dimensional stability aids repeatable inspection routines without the need for complex fixtures.

Robust workshop design that supports daily use

Built in a workshop execution and made from special steel, the pin balances durability and handling for routine measurement tasks. At 50 mm overall length and a mass of approximately 0.008 kg, the component is compact and easy to manoeuvre while remaining suitably rigid for short‑range verification work. Supplied as a single piece and packed in a protective transport box, the unit arrives ready for safe storage and immediate use, protecting the measuring face during transport and preventing accidental damage between inspections.

Labelling and supply advantages for industrial workflows

Cataloguing is straightforward with the visible SKU M323.431 and the supplied GTIN, which facilitate inventory control and traceability in production environments. The pin is designed for integration into established inspection routines as an end‑measure standard for small bores and mating parts. Metav IndustryLine’s distribution from Emmerich offers an accessible quality filter for European purchasers, supporting reliable replenishment and documented product data for technical planning.
