Gauge Pin M323.C39 — Single precision test pin, Ø 12.39 mm, 50 mm length (Metav IndustryLine)

The Gauge Pin M323.C39 is a single precision test pin designed for end‑measurement and go/no‑go checks in workshop and production environments, optimised for repeatable inspection tasks

• Workshop version for robust everyday use
• Diameter precisely 12.39 mm, tolerance ±0.002
• 50 mm overall length for standard test setups
• Made from special steel for longevity

Consistent precision that reduces rejects

The M323.C39 is specified with an accuracy of ±0.002 mm, which translates directly into fewer false rejects and less downstream rework when used in routine inspection or fixture checks. A controlled nominal diameter of 12.39 mm means the pin can be relied upon as a reference element in measuring jigs or when verifying bore sizes close to the nominal dimension. The tight tolerance ensures measurements remain stable across repeated cycles, so process capability and traceable sampling benefit from reduced scatter.

Durable design for daily workshop use

Constructed from special steel and offered in a workshop version, the test pin is built to withstand regular handling on the shop floor while retaining dimensional stability. The 50 mm overall length provides a familiar geometry for standard test fixtures and gauge blocks, allowing straightforward integration into existing setups. A modest mass of 0.1 kg ensures the component is easy to position without risking excessive inertia in small assemblies, and the material choice prioritises wear resistance and longevity under repetitive contact.

Fits into quality workflows and inspection sets

As a dedicated gauge pin, this component suits a range of metrology tasks such as end‑dimension verification, seating checks and simple go/no‑go assessments within production control. The clear numeric specification (diameter, length and tolerance) simplifies documentation and helps maintain consistent acceptance criteria in inspection instructions. When combined with calibrated masters or datum fixtures, the pin supports a rational inspection strategy that emphasises measurable outcomes and traceable results, contributing to faster decision‑making on the shop floor.
