Gauge pin M323.378 — 3.78 mm ±0.001 mm, 50 mm length (Metav IndustryLine)

The gauge pin M323.378 is a single precision test pin designed for end‑measure checks and go/no‑go referencing in workshop metrology.

• Precision tolerance ±0.001 mm
• Diameter 3.78 mm for fine verification
• 50 mm length for secure seating and reach
• Workshop version supplied in transport case

Accurate reference for end‑measure verification

A compact precision pin with a nominal diameter of 3.78 mm and a tolerance of ±0.001 mm serves as a stable reference for end‑dimension checks and small‑bore verification. The tight tolerance reduces measurement uncertainty and supports reliable pass/fail decisions in routine inspections. As a hardened concept in workshop use, this test element speeds up verification cycles, helping to maintain production flow and minimise rework caused by ambiguous fits.

Durable material and practical handling

Manufactured from special steel, the pin balances wear resistance with a slim profile; the 50 mm length provides sufficient engagement without excessive overhang, improving handling and repeatability when seated in gauges or fixtures. Supplied as a single piece in the workshop version, the test pin arrives protected in a transport case to prevent transit damage and to keep the datum face clean. Lightweight construction aids rapid changeovers on benches and within inspection fixtures.

Seamless integration into inspection routines

The plug‑style test pin is suitable as a reference in plug gauges, alignment tools and fixture setups where consistent end‑faces are required. Using a dedicated gauge pin with ±0.001 mm tolerance simplifies calibration of go/no‑go systems and supports statistical process control by providing a known reference point. The compact design allows easy storage alongside other metrology tools while preserving traceable dimensional checks when integrated into quality workflows.
