Gauge pin M323.378 — Metav IndustryLine, 3.78 mm, ±0.001 mm tolerance

The gauge pin M323.378 is a workshop‑grade precision pin for quick dimensional verification and end‑measure control in industrial metrology applications.

• 3.78 mm diameter with ±0.001 mm tolerance
• Length 50 mm, workshop‑grade construction
• Made from special steel for dimensional stability

Accurate checks with measurable benefits

The gauge pin delivers industrial‑grade precision for repeatable plug and fit verifications. With a diameter of 3.78 mm and a tight ±0.001 mm tolerance, it is designed for applications where micrometric certainty reduces rework and scrap. The compact geometry and stable material properties enable consistent contact conditions during go/no‑go checks and fixture validation, increasing throughput by avoiding ambiguous fits.

Built for rough workshop conditions and routine metrology

Constructed as a workshop‑grade instrument, this precision pin combines robust handling with dimensional fidelity. The 50 mm length provides sufficient engagement for hole gauges and assembly trials while remaining easy to manoeuvre by hand or in jig fixtures. The special steel composition ensures wear resistance under repeated insertion cycles, allowing longer service life and stable calibration intervals for routine quality‑control workflows.

Integration into inspection processes and traceable documentation

This single gauge pin supports fast end‑measure inspections and is suitable for use on manual gauges, fixture checks and as a reference in comparative measurements. The compact form and consistent surface finish reduce measurement variability during tactile checks. For organisations standardising inspection routines, the gauge pin M323.378 is straightforward to include in inspection plans, improving process reliability and auditability without adding complexity.
