Gauge pin M323.821 — precision gauge pin, 8.21 mm ±0.001 mm, 50 mm length (Metav IndustryLine)

The Gauge pin M323.821 is a workshop-grade precision plug intended for final-dimension and end‑mass checks in metrology and production environments

• Diameter 8.21 mm, tolerance ±0.001 mm
• Length 50 mm for compact measurements
• Made from special steel, workshop grade

Consistent precision for final inspections

A tolerance of ±0.001 mm positions this gauge pin in the high‑precision segment used for critical end‑dimension checks. The tight tolerance reduces uncertainty in pass/fail decisions, which in turn lowers rework rates and increases throughput in inspection stations. By using a fixed-diameter reference of 8.21 mm, traceable checks on bores, seats and mating parts become repeatable and quick to execute, supporting lean quality processes and faster cycle times.

Durable workshop design for dependable handling

Constructed from special steel and specified as a workshop-grade item, the pin delivers wear resistance and stable geometry under routine use. The 50 mm length provides a compact grip area and sufficient engagement for short-seat or through-bore verification, while the low mass supports easy handling during repetitive tests. The robust finish minimises the need for frequent replacement, making the component a practical choice where reliability and uptime matter.

Seamless fit into inspection workflows

Equipped with a clear identification (SKU M323.821) and industry-standard data for procurement, the pin integrates into existing quality routines without extra adaptation. Its compact form factor simplifies storage and pick‑and‑place handling at measuring benches or inspection fixtures, and its repeatability supports statistical process control activities. Metav’s supply chain and quality filter in Emmerich ensure consistent availability and compatibility with workshop inventories, enabling organisations to democratise precision across multiple workstations.
