Gauge pin M323.331 — 3.31 mm diameter, ±0.001 mm tolerance (workshop version, Metav IndustryLine)

Gauge pin M323.331 is a precision test pin intended for dimensional checks and end‑size verification in inspection and workshop routines.

• Workshop version, robust design
• Diameter 3.31 mm with ±0.001 mm accuracy
• Compact 50 mm length for end measurements
• Special steel construction for durability

Exceptional precision for end‑size verification

The M323.331 gauge pin delivers a tolerance of ±0.001 mm, a level of precision that supports tight dimensional control in component inspection and quality assurance workflows. Such accuracy is particularly relevant where end‑measurements determine assembly fit or tolerance chains. By using a dedicated 3.31 mm reference pin with a short 50 mm length, repeatable positioning and minimal deflection are achieved during routine checks, ensuring that measurement outcomes are consistent and traceable.

Designed for regular workshop use and straightforward handling

Manufactured in a workshop version and from special steel, this test pin combines a compact form factor with a lightweight profile (approx. 0.006 kg) that facilitates comfortable handling during frequent inspections. The material choice and construction suit standard workshop procedures and contribute to dimensional stability over many cycles of use. The short length simplifies access in confined setups while preserving the rigidity required for reliable end measurements.

Clear identification and practical integration into inspection routines

Supplied as an individual precision pin, the item is intended for targeted verification tasks rather than set‑only applications. Traceability is supported by the clear article identification (M323.331) and GTIN, which aid inventory management and procurement. Integration into existing inspection jigs or plug checks is straightforward thanks to the precise 3.31 mm diameter and standardised tolerance class, making the pin a practical reference tool for workshop metrology and final checks.
