Gauge pin M323.400 — single precision gauge pin, Ø 4.00 mm ±0.001 mm, 50 mm (Metav IndustryLine)

The Gauge pin M323.400 is a single precision reference pin designed for end‑measure verification and fit testing in workshop metrology.

• Single precision gauge pin Ø 4.00 mm ±0.001
• Length 50 mm for reliable end‑measure checks
• Made from special steel, workshop version
• Supplied in a protective transport box

Consistent tolerances for dependable inspection results

The core advantage of this gauge pin lies in its ±0.001 mm tolerance, which supports highly reproducible limit measurements and tight fit checks in small‑component production. Where control of final diameters and end‑faces matters, the fine tolerance reduces uncertainty in pass/fail decisions and shortens inspection cycles. The compact diameter supports micro‑scale verification tasks while maintaining high precision and repeatability.

Robust workshop design that endures daily use

Built as a workshop version from special steel, the pin combines a compact form with durable construction suited to routine handling and fixture use. The balanced mass and short length reduce the influence of wobble or deformation during insertion, so measurements remain stable over multiple cycles. This robustness means the pin is practical for bench inspection, small jig checks, and quick comparative tests in production areas.

Compact dimensions and practical storage for busy shops

With a 50 mm overall length and Ø 4.00 mm diameter, the gauge pin is easy to position in confined fixtures and to pack with other metrology tools. Supplied in a protective transport box, the item is protected against transit damage and contamination until use, streamlining storage and transport. Its small weight also simplifies handling when several reference pins are needed for a set of go/no‑go checks.

Typical applications and compatibility in inspection workflows

The pin is intended as a reference for end‑measure checks, plug‑fit verification and assembly trials where precise small diameters are critical. In fixture construction and quality control stations it functions as a dimensional standard for matching holes, seats and mating parts. Identification details (SKU M323.400) allow simple integration into inventory and traceability systems for consistent process documentation.

FAQ

What tolerance can be expected from this gauge pin?
The gauge pin offers a tolerance of ±0.001 mm, giving highly repeatable results for end‑measure and fit checks with the Metav IndustryLine gauge pin M323.400.

Is the pin supplied with calibration documentation?
The delivery does not state ISO 17025 calibration; the gauge pin is supplied in a protective transport box but does not include an ISO 17025 certificate by default.

Which material is used for the gauge pin?
The gauge pin is manufactured from special steel, specified for the Metav IndustryLine single precision gauge pin to provide workshop‑grade durability.

Can this pin be used for plug and seat verification in fixtures?
Yes, the 4.00 mm diameter and precise tolerance make the pin suitable as a reference for plug‑fit and seat verification in fixture and assembly checks.

How does the compact length affect measurements?
The 50 mm length keeps the pin rigid and easy to handle, reducing measurement variability in short‑reach inspection tasks and making it suitable for confined fixture applications.
