Gauge pin M323.C46 — single precision gauge pin, Ø 12.46 mm, 50 mm length (Metav IndustryLine)

A single gauge pin (M323.C46) for quick, repeatable verification of end dimensions and hole conformity in workshop and production environments.

• Diameter 12.46 mm with ±0.002 mm tolerance
• 50 mm workshop length for robust handling
• Made from special steel for wear resistance
• Supplied in a protective transport case

Reliable checking of end dimensions for production control

This measurement pin is designed for straightforward verification of final dimensions in assemblies and machined bores. The 12.46 mm nominal diameter, produced to a deviation of ±0.002 mm, provides a dependable go/no‑go reference for fit checks and quality gates. The special steel construction keeps the gauge stable under routine use, reducing the frequency of replacement and the risk of undetected rework. Using a dedicated pin like this converts bore measurement into a rapid, repeatable operation that supports consistent production throughput.

Workshop-ready build that reduces handling errors

Built as a workshop version, the pin’s 50 mm length balances reach with stiffness to ease manual gauging in bench and cell work. The chosen geometry minimises deflection when inserting into tight tolerances, ensuring the result reflects the component, not the tool. The sturdy finish improves resistance to nicks and wear during daily use; together with the compact mass, this design reduces operator fatigue during repetitive checks and helps maintain measurement quality across shifts.

Practical protection and traceable identification

Delivery in a transport case prevents accidental damage and keeps the pin ready for immediate use on the shop floor. The item is supplied as a single gauge pin with clear identification (SKU M323.C46, GTIN 4061905067105), allowing simple inventory tracking and replacement planning. Lightweight and easy to store, the packaged pin supports a controlled inspection workflow while protecting the measurement surface against contamination and accidental impacts.

Efficiency gains and quality assurance benefits

Integrating a precision gauge pin into incoming inspection, setup procedures or final inspection reduces time per check and limits interpretation variability. The high repeatability of a hardened pin with a defined nominal diameter eliminates the need for elaborate fixtures in many standard checks, thereby streamlining operations and lowering downstream scrap rates. Confidence in dimensional conformity leads to fewer production interruptions and a clearer audit trail for quality records.
