Gauge pin M323.644 — gauge pin, 6.44 mm diameter, ±0.001 mm accuracy

The gauge pin M323.644 is a workshop-grade measuring pin designed for precise end-dimension inspection and fixture set-up in production and quality control environments.

• Workshop-grade precision pin Ø 6.44 mm
• Tolerance ±0.001 mm for tight checks
• Length 50 mm for end-dimension control
• Special steel construction for durability

Precision that stops ambiguity in fit and assembly

The compact measuring element delivers a nominal diameter of 6.44 mm with a guaranteed positional accuracy of ±0.001 mm, making it suited to tasks where interchangeability and minimal clearance are critical. As a hardened gauge pin, it provides a defined reference for hole gauges, go/no-go tests and alignment operations; the fine tolerance reduces doubt in pass/fail decisions and supports consistent assembly results. This level of precision is particularly valuable where even small deviations would compromise sealing, bearing fits or functional tolerances.

Robust construction for everyday workshop use

Manufactured in special steel and offered in a workshop-grade configuration, the measuring pin combines wear resistance with practical handling characteristics. The 50 mm overall length supplies sufficient reach for many end-dimension checks while remaining easy to position in jigs and fixtures. Because the design prioritises mechanical stability, thermal effects and surface wear are less likely to cause measurement drift, which benefits repeatability in routine inspections and long production runs.

Practical applications and process benefits

The pin is intended for direct insertion checks, gauge setting and fixture referencing in inspection benches and assembly lines; it supports reliable end-measurement control for components such as dowels, bores and shafts. Using a dedicated measuring pin like this reduces cycle time for manual checks and improves comparability across shifts. Combined with Metav’s quality filter and supply chain reliability, the component helps industrial and workshop teams maintain consistent production quality without adding procurement complexity.
