Test pin M323.878 — Gauge pin, 8.78 mm diameter, ±0.001 mm accuracy (Metav IndustryLine)

The test pin M323.878 is a single gauge pin designed for dimensional inspection and plug‑gauge applications in workshop and inspection environments.

• Diameter 8.78 mm ±0.001 mm tolerance
• Length 50 mm for standard inspection tasks
• Special steel construction for wear resistance
• Workshop version with robust finish

Repeatable accuracy for inline inspection

The compact cylindrical plug provides ±0.001 mm nominal tolerance, offering a stable reference for tactile inspection and fixture checks. With a nominal diameter of 8.78 mm, the pin functions as a precision reference for bore checks, setting gauges and comparator setups; the tight tolerance reduces measurement uncertainty and helps maintain consistent production control. The hardened, wear‑resistant surface preserves the diameter under frequent use, which benefits repeatability across inspection cycles.

Robust design that endures workshop use

Machined from special steel and finished for service in demanding environments, this inspection pin is classified as a workshop version to withstand handling and repeated seating in fixtures. The 50 mm length gives sufficient engagement for stable measurements while remaining easy to handle during batch checks. Reduced surface wear and a compact form factor simplify storage and integration in pin sets or inspection kits, ensuring the reference remains accurate over extended service life.

Practical integration into quality routines

As a single‑piece inspection element, the gauge pin simplifies process controls and visualising tolerances on the shop floor. Marked with the item identity and GTIN for traceability, the component serves as a quick reference for go/no‑go testing, fixture set‑up and comparative gauging. Documents and SOPs benefit from the clear numerical specification (8.78 mm, 50 mm, ±0.001 mm), enabling straightforward acceptance criteria and auditability in standard quality workflows.
