M323.491 Pin Gauge — 4.91 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The M323.491 is a single precision pin gauge designed for workshop use and end‑dimension verification in production and inspection environments.

• Workshop-grade design
• Diameter 4.91 mm for end measurements
• Tolerance ±0.001 mm for ultra-fine accuracy
• Supplied in protective transport case

Precision that keeps production within tolerance

A compact cylindrical gauge engineered for repeatable end‑measurements, this inspection pin offers a tolerance of ±0.001 mm, which places it in the sub‑micron class for gauging tasks. The extremely fine tolerance reduces ambiguity in pass/fail decisions during incoming inspection or process control. The construction from special steel ensures dimensional stability under normal workshop conditions, while the modest mass aids quick handling and minimal thermal influence. This combination supports faster quality checks and fewer callbacks for rework.

Robust handling for demanding workshop environments

Built as a workshop‑grade tool, the pin gauge is resilient to typical handling and storage in production areas. The 50 mm length gives sufficient engagement for hole and bore checks without excess overhang, improving alignment during measurement. Delivery in a protective transport case protects the cylindrical end faces from nicks and contamination, helping to maintain accuracy between uses. These design choices contribute to lower lifecycle costs by preserving the datum surfaces that determine measurement reliability.

Clear role in measurement routines and setup

As a straightforward cylindrical reference, the pin functions as a reliable standard for end‑dimension verification, gauging fixtures and go/no-go checks. Its simple geometry means compatibility with visual inspection, plug gauging and comparative checks against calibrated masters. The compact size and defined diameter make it suitable for tight cavities where larger gauges cannot reach, while the defined tolerance supports traceable acceptance criteria in workshop documentation and inspection plans.
