Gauge pin M323.I31 – Single test pin, Ø 18.31 mm, 50 mm length (Metav IndustryLine)

A single gauge pin, bold in accuracy and made for workshop reference and plug-gauge tasks

• High-precision tolerance ±0.002 mm
• Diameter 18.31 mm for precise fits
• Robust special steel construction
• Delivered in protective transport case

Reliable reference measurements that reduce rework

The gauge pin M323.I31 serves as a stable reference for fit and clearance checks, offering a declared tolerance of ±0.002 mm. This nominal accuracy translates into repeatable results when used as a go/no-go reference or as a setting standard in calibration jigs. The tight tolerance reduces variability during batch inspections and helps to limit scrappage and rework by ensuring that mating parts conform to the intended clearance. In practical terms, the pin supports quicker go/no-go decisions and consistent quality control documentation.

Built for workshop handling with sustained durability

Manufactured from special steel and specified as a workshop version, this test pin balances wear resistance with manageable handling. The 50 mm length and smooth finished surface make it straightforward to seat in fixtures or to use as a plug gauge when verifying bore diameters. The supplied protective transport case preserves the measuring surface during storage and transit, maintaining the nominal diameter and thus the measurement integrity over time. Robust material choice and protective packaging together ensure longevity under daily workshop conditions.

Practical integration into inspection and assembly workflows

With a clear nominal diameter of 18.31 mm, the pin integrates into existing inspection benches, assembly fixtures and gauge sets as a precision reference. Its stable geometry shortens setup times when replacing worn references or switching between inspection tasks. The compact format is especially useful where space is constrained or when multiple reference pins are carried between workstations. Using standardised references like this test pin helps maintain process capability and simplifies traceability in production records.
