Gauge pin M323.321 — single 3.21 mm, tolerance ±0.001 mm (Metav IndustryLine)

The Gauge pin M323.321 is a workshop‑grade precision pin for end‑measurements and bore verification in inspection and production environments

• Precision tolerance ±0.001 mm
• Diameter 3.21 mm for end‑measurements
• Length 50 mm workshop version
• Supplied in a transport case

Reliable results where every micron matters

A compact test pin with ±0.001 mm tolerance provides measurable benefits in quality control: repeatable fits, reduced rework and clear go/no‑go decisions. The 3.21 mm diameter is specified for precise end‑measurements and plug verification; its narrow tolerance converts directly into traceable inspection outcomes. Made from special steel, the pin resists deformation under normal handling and preserves surface integrity, ensuring that measured deviations reflect the part, not the gauge. This technical certainty supports faster in‑process checks and consistent documentation in routine inspection plans.

Workshop‑ready design for efficient handling

Designed as a workshop version, the test pin combines a 50 mm working length with a compact form factor that simplifies manual insertion and removal in confined jigs or fixtures. The light overall mass promotes swift handling during batch inspections while the robust finish reduces wear from frequent use. Supplied in a transport case, the pin is protected during storage and transit, which maintains dimensional stability and reduces downtime caused by damaged gauges. This configuration supports lean inspection workflows and helps maintain a steady production throughput.

Practical integration and measurement confidence

In practice, a precision gauge pin like this one shortens decision loops: measured deviations can be acted on immediately, limiting scrap and minimising adjustment cycles. The pin’s geometry and material choice favour consistent contact conditions, improving repeatability across operators. Classification within the micro measurement class highlights its suitability for fine mechanical tasks and small‑bore verification where stiffness and minimal run‑out are required. For traceable inventory, the pin is identifiable by SKU and GTIN, supporting quality records and part‑lot traceability in controlled environments.
