Gauge pin M323.891 — Single precision plug gauge, Ø 8.91 mm, ±0.001 mm (Metav IndustryLine)

Gauge pin M323.891 is a single precision plug gauge intended for end‑measurement and go/no‑go fit checks in inspection and production

• Diameter 8.91 mm, tolerance ±0.001 mm
• Robust special steel construction
• Length 50 mm for deeper seat checks
• Workshop version for frequent use

Precision that ensures reproducible fit checks

A consistently tight tolerance is the foundation of efficient quality control. This gauge pin delivers a declared tolerance of ±0.001 mm (1 µm), enabling clear go/no‑go decisions and reducing ambiguous rejects. The fine tolerance makes the pin suitable for high‑accuracy inspection tasks, where reproducibility across repeated measurements preserves batch quality and shortens inspection cycles. The clear numerical specification supports traceable acceptance criteria for production.

Durable construction for workshop environments

Manufactured from special steel, the pin is designed for regular handling and contact with mating bores. The workshop version means surface finish and heat treatment have been selected to withstand frequent use while maintaining the measured diameter. At a mass of 0.029 kg and a length of 50 mm, the pin is easy to position for deeper seat checks without compromising rigidity, supporting faster, safer handling at the inspection bench.

Practical applications and compatibility in metrology setups

This single plug gauge is intended for end‑masses and fit verification in assembly and incoming inspection. Typical uses include acceptance checks of bored holes, fixture validation and successor checks in serial production. The clear specification (Ø 8.91 mm, ±0.001 mm) makes it suitable as a reference gauge in comparison benches or as a dedicated tool within a gauge set. Traceability is supported by the provided article details and GTIN for inventory systems.
