Gauge pin M323.494 — Single precision gauge pin, Ø 4.94 mm, ±0.001 mm (Metav IndustryLine)

A Gauge pin M323.494 engineered for precise end‑dimension and reference measurements in metrology and workshop inspection tasks.

• Absolute tolerance ±0.001 mm
• Diameter Ø 4.94 mm for tight fits
• 50 mm overall length, workshop design
• Single unit delivery for flexible use

Reliable tolerance for decisive inspection results

A clear advantage of this gauge pin is the ±0.001 mm tolerance, which provides a dependable reference for dimensional verification in quality control. Such a fine tolerance reduces ambiguity when checking end dimensions and mating fits; the small allowance translates into fewer false rejects and faster acceptance decisions on production lines. Used as a datum or reference mandrel, the pin’s precise diameter supports repeatable checks against plug gauges, bore gauges and comparator setups, helping to maintain throughput without compromising measurement integrity.

Built for workshop durability and repeatable handling

Manufactured from special steel, the pin combines surface robustness with low mass (approx. 0.01 kg) for comfortable handling during routine inspections. The 50 mm overall length balances accessibility with stiffness, allowing the pin to be used as a handheld reference or within fixture jigs where space is limited. The workshop execution emphasises practical longevity: the material choice and compact geometry minimise wear at contact points, which preserves dimensional fidelity over extended use and reduces the need for frequent replacement.

Seamless integration into quality workflows

This single precision pin fits into existing gauge sets and inspection benches without additional adaptation, making it straightforward to include in incoming inspection, in‑process checks or final control operations. Labelled and traceable by article number, the component supports organised inventory and quick identification in tool cabinets and gauge trays. For specialised applications or advice on fixture integration, Metav IndustryLine provides technical guidance to ensure the pin fulfils the intended measuring role and contributes to stabilised process quality.
