M323.284 — Single gauge pin, Ø 2.84 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The M323.284 is a single gauge pin designed for high-precision end-dimension inspection in workshop environments, ideal for fine component verification and tooling set-up.

• Workshop-grade manufacture for daily use
• Diameter tolerance ±0.001 mm for high precision
• Compact 50 mm length for tight inspection spaces
• Delivered in a protective transport case

Precision that reduces rework and inspection time

This gauge pin delivers sub-micron-level accuracy with a specified tolerance of ±0.001 mm, ensuring repeatable checks of small bores and end dimensions. The tight tolerance reduces measurement uncertainty and lowers the risk of undetected deviations that can lead to costly rework. Thanks to the compact geometry, the inspection pin slides into confined features with minimal handling disturbance, enabling faster go/no‑go decisions on the shop floor and more efficient quality-control cycles.

Built for practical workshop use and durability

Manufactured in special steel and offered in a workshop version, the pin balances surface finish and robustness for everyday use. The 50 mm length and small diameter create a very low-profile tool that is easy to manoeuvre in fixtures or handheld checks. Supplied in a transport case, the item is protected during storage and transit, which helps preserve the calibrated condition and prevents surface damage that could compromise accuracy.

Suitable application range and handling advice

Classified among micro measuring tools due to its small dimensions, this inspection pin is intended for fine mechanical work where precise end measurements are required. Its geometry makes it well suited for checking small bores, gauge trials and assembly controls in watchmaking, precision engineering and tooling workshops. When using the pin, ensure clean contact surfaces and consistent seating to maintain the stated tolerance; even with high-quality material and finish, proper handling is essential to preserve measurement integrity.

Efficiency and procurement benefits for workshops

Choosing a workshop-grade gauge pin with this level of specification streamlines inspection routines and supports reliable production control. The compact design minimises the need for special fixtures, while the narrow tolerance band improves conformity assessment. As part of Metav’s line-up, the component contributes to a broader approach of making precision tools accessible and dependable for everyday industrial use.
