M323.349 gauge pin — 3.49 mm diameter, ±0.001 mm tolerance (Metav IndustryLine)

M323.349 gauge pin is a single‑piece inspection pin optimised for precise end‑dimension checks and reliable use in workshop environments

• Workshop version for robust use
• Diameter 3.49 mm, tolerance ±0.001 mm
• Length 50 mm, compact handling
• Supplied in transport case

Accuracy that keeps production within tolerance

The M323.349 is engineered for tasks where reproducibility matters: with a diameter of 3.49 mm and an accuracy of ±0.001 mm, this inspection pin provides a measurable reduction in uncertainty during go/no‑go checks and end‑dimension controls. The ultra‑fine tolerance translates into fewer rejected parts and less time spent on rework, which improves throughput in small‑batch and serial inspection routines. The narrow diameter and precise ground finish ensure consistent seating in gauges and fixtures, supporting reliable statistical process control.

Built for workshop use and simple handling

A workshop version implies durability under routine use: the shaft is made from special steel, heat treated and ground to ensure wear resistance and surface stability. The 50 mm length offers a balanced combination of reach and stiffness, enabling single‑handed positioning without excessive deflection. Supplied in a protective transport case, the pin is safeguarded from handling damage between measurements, so traceability and dimensional integrity are maintained from storage to the inspection station.

Clear application fit and measurable benefits

Intended as a precision measuring pin for end‑dimension verification, the component fits inspection jigs, comparator fixtures and checking benches where small‑diameter gauges are required. The combination of compact geometry and high repeatability supports efficient in‑process checks during assembly and final inspection. As a product within Metav IndustryLine, the gauge pin is matched to professional metrology workflows and complements existing gauge sets without the need for elaborate fixtures.
