Gauge pin M323.521 — 5.21 mm / ±0.001 mm (Metav IndustryLine)

Gauge pin M323.521 is a single precision inspection pin for workshop measurement and end‑size verification, designed for repeatable fit and go/no‑go checks

• Workshop-grade finish
• Diameter 5.21 mm ±0.001 mm
• Length 50 mm precision pin
• Special steel construction

Precise tolerance for reproducible inspection results

The gauge pin is manufactured to an extremely fine ±0.001 mm tolerance, which corresponds to a one‑micrometre deviation band. This level of accuracy places the component among high‑precision inspection tools and supports quality control routines where dimensional reproducibility is critical. The defined nominal 5.21 mm diameter enables reliable plug‑type checks and supports statistical process control by reducing measurement scatter; traceable batch characteristics and the exact tolerance make it suitable for calibration benches and assembly verification.

Robust workshop design that reduces downtime

Built in a workshop specification, the pin features special steel chosen for dimensional stability and resistance to everyday wear. The compact 50 mm length promotes easy handling and secure seating in fixtures or gauges while maintaining stiffness for repeatable contact. The result is a durable inspection aid that tolerates routine use without rapid degradation, thereby lowering maintenance intervals and supporting continuous production checks in machine shops and inspection stations.

Integrating the pin into inspection workflows

As an inspection tool, the pin is straightforward to integrate into existing fixtures and gauges for end‑size inspection, clearance testing and reference checks. Its compact form and precise diameter make it suitable for bench testers and fixture-based verification. Where tight fits and consistent mating are required, the pin serves as a dependable reference for go/no‑go assessments and comparative measurement routines, helping to secure part conformity before assembly or shipment.
