Gauge pin M323.381 – 3.81 mm, ±0.001 mm (Metav IndustryLine)

The gauge pin M323.381 is a single hardened test pin designed for accurate end‑dimension checks and bore gauging in workshop environments.

• Diameter 3.81 mm ±0.001 mm tolerance
• Length 50 mm for bore and end measurement
• Workshop version for robust everyday use
• Supplied in transport case for safe storage

Precision that reduces rework

The M323.381 delivers a diameter accuracy of 3.81 mm with a ±0.001 mm tolerance, enabling sub‑micrometre certainty when validating bore sizes or end dimensions. Such fine tolerance narrows process variation and reduces the need for corrective machining, translating into fewer rejects and lower rework costs. This level of control is particularly valuable in small‑batch work and precision assembly where every micron counts.

Stable geometry for repeatable reference measurements

A constant shaft profile and a fixed 50 mm overall length provide a reliable reference in repetitive inspection tasks. The geometry minimises flex and ensures consistent seating in test fixtures and gauge blocks, so measurements remain comparable across shifts. By offering a stable reference dimension, the pin supports traceable inspection routines and straightforward tolerance comparisons on the shop floor.

Built for workshop durability

Manufactured from special steel, the pin combines wear resistance with dimensional stability under normal workshop conditions. The workshop specification ensures that the tool withstands frequent handling and routine cleaning without compromising accuracy. Supplied in a protective transport case, the pin arrives ready for use and storage, reducing the risk of transport damage or surface contamination.

Easy integration into inspection procedures

The compact single‑pin design fits into common inspection jigs and manual measuring sequences without complex adaptation. Its straightforward form factor makes it suitable for quick go/no‑go checks, plug‑gauge comparisons and as a reference for setting measuring instruments. Using a single, well‑specified reference reduces procedure complexity and shortens inspection times.

Practical benefits for everyday metrology

Beyond raw accuracy, the pin supports better workflow: quick identification via SKU, compact handling for tight work areas, and resilient material choice for frequent use. The combination of precision, durability and simple handling helps maintain production rhythm and supports consistent quality control across repetitive tasks.
