Gauge pin M323.C31 — single test pin, Ø 12.31 mm, 50 mm length (Metav IndustryLine)

Gauge pin M323.C31 is a single precision pin designed for end‑dimension checking and fixture set‑ups in workshop environments

• Workshop-grade design for daily use
• Ø 12.31 mm precision, tolerance ±0.002 mm
• Made from special steel

Consistent end‑dimension verification for fast decisions

The gauge pin M323.C31 delivers high repeatability for quick acceptance checks and go/no‑go verifications. With a nominal diameter of Ø 12.31 mm and a declared tolerance of ±0.002 mm, the pin gives a measurable and comparable reference for bore checks, plug‑fit tests and production sampling. The narrow tolerance supports reduction of measurement uncertainty during routine inspections and accelerates decision‑making on the shop floor by providing an unambiguous reference dimension.

Robust construction that withstands regular handling

Manufactured from special steel, this single test pin is specified for workshop use where durability matters. At 50 mm length and a mass around 0.10 kg, the pin is compact yet substantial enough to remain stable during insertion and withdrawal, reducing deformation risks that can affect results. The workshop‑grade build ensures sustained surface integrity under repeated use, which preserves the accuracy level and maintains reliable contact geometry over many cycles.

Easy integration into setup and inspection routines

The pin functions as a simple master for fixture alignment, quick setting of gauges and verification of mating parts; its straight, cylindrical form makes it suitable for manual and semi‑automated checks. When used as a reference plug, the M323.C31 helps to shorten set‑up times and to avoid iterative adjustments, supporting leaner workflows. For bespoke measurement tasks, Metav IndustryLine offers advice on complementary sizes and compatible inspection tools to build a practical gauge set for production or maintenance contexts.
