Pin Gauge M323.649 — Single precision gauge pin, Ø 6.49 mm, ±0.001 mm (Metav IndustryLine)

A pin gauge M323.649 designed for precise end‑measure verification and bench inspection in workshop and quality‑control environments.

• Diameter 6.49 mm with ±0.001 mm tolerance
• 50 mm overall length in workshop design
• Made from special steel
• Supplied in protective transport case

Micron accuracy for repeatable end‑measure checks

The core advantage of this gauge pin is its ±0.001 mm tolerance, which corresponds to a one‑micrometre deviation allowance. Such precision places the part firmly in the micro measurement class, making it suitable where tiny clearance checks and tight end‑dimensions are critical. The narrow diameter of 6.49 mm offers stable contact behaviour while keeping mass low, so inspections remain consistent over many cycles. This level of accuracy supports reliable go/no‑go comparisons and reference checks in component inspection routines.

Robust workshop format for dependable handling

Built as a workshop execution, the pin combines compact geometry with a practical overall length of 50 mm, optimised for handheld inspection and fixture use. The choice of special steel gives the pin a balance of wear resistance and dimensional stability under normal workshop conditions. Delivery in a protective transport case reduces the risk of transit damage and keeps the gauge accessible on the bench; the case is intended for transport protection and safe handling rather than long‑term storage under uncontrolled conditions.

Practical applications and measurement benefits

This single pin gauge is intended for precise end‑mass checks, reference measurements and small‑part inspection in toolrooms, assembly and precision manufacturing. The controlled tolerance simplifies decision making during quality checks: components that fit within the specified limit can be accepted with documented traceability, while deviations are immediately identifiable. For fine mechanical and micro‑assembly tasks the compact form factor ensures good accessibility in confined geometries without sacrificing measurement confidence.
