Gauge pin M323.646 — Inspection pin, 6.46 mm, ±0.001 mm (Metav IndustryLine)

The gauge pin M323.646 is a precisely ground inspection pin for end-measure checks and fitting applications in workshop and metrology environments.

• Precisely ground to ±0.001 mm tolerance
• Diameter 6.46 mm for accurate plug-fit checks
• Robust 50 mm length for stable handling
• Workshop version with durable special steel

Precision that secures reproducible measurements

The primary strength is the uncompromising tolerance of ±0.001 mm, which translates into measurable gains in quality control: fewer false rejects, reduced rework and consistent assembly fits. A 6.46 mm diameter pin with a fine tolerance provides a defined datum for go/no‑go assessments and press‑fit verifications. For production and inspection routines, this level of repeatability shortens cycle times by removing subjective judgement from tight fit checks and supports traceable dimensional documentation.

Robust construction for repetitive workshop use

Constructed from special steel and finished for long service life, the inspection pin withstands repeated seating and withdrawal in jigs and gauges. The compact 50 mm length keeps bending and handling errors to a minimum while preserving adequate grip area for fast, one‑hand operation. The workshop specification prioritises durability and straightforward maintenance: hardened surfaces resist fretting and preserve the ground diameter so that functional accuracy endures over prolonged use.

Integrating the pin into inspection and assembly workflows

This inspection pin is optimised for end‑gauge tasks, calibration fixtures and plug-fit validation in component assembly. The compact design simplifies storage in sets or racks and allows rapid substitution in modular gauges. Backed by Metav’s distribution and quality assurance, the pin supports a stable supply chain for workshops and small series manufacturing. The clear technical definition reduces ambiguity at procurement and helps quality managers embed a reproducible measurement standard into daily production.
