Gauge pin M323.322 — single precision test pin, 3.22 mm diameter, ±0.001 mm accuracy (Metav IndustryLine)

The gauge pin M323.322 is a single precision test pin designed for micro‑range end‑dimension inspection and workshop quality control.

• Precision tolerance ±0.001 mm
• Diameter 3.22 mm in special steel
• Length 50 mm for versatile inspection tasks
• Workshop execution for everyday robustness

Accuracy that secures repeatable measurements

With a declared tolerance of ±0.001 mm, this test pin delivers measurement certainty where small deviations matter. The extremely tight tolerance translates into reliable pass/fail decisions during incoming inspection and assembly checks, reducing the need for repeated measurements and downstream rework. For fine‑mechanical parts, where even micrometre shifts affect fit, the available accuracy supports consistent quality control and process stability.

Compact design optimised for micro‑components

Classified for the micro range, the small 3.22 mm diameter and compact geometry minimise flex and contact variation during use. This form factor is particularly beneficial for small bores, pin fits and precision assemblies in toolmaking and horology, where short measurement spans help maintain alignment and reduce operator‑induced error. The compact size also allows easy integration into check jigs and fixtures used on the shop floor.

Material choice for durable service life

Manufactured from special steel, the pin combines hardness with surface integrity to withstand repeated insertion and removal in production inspections. The material selection reduces abrasive wear and preserves the calibrated diameter over extended cycles, supporting long‑term reproducibility of results and lowering the total cost of ownership in routine inspection tasks.

Practical length for handling and fixture use

A 50 mm overall length provides sufficient reach for a wide range of component checks while remaining manageable for single‑hand operation and fixture mounting. The length balances accessibility and control: long enough to engage deep bores and features, yet short enough to keep deflection negligible during manual measurements, so readings remain trustworthy without elaborate supports.

Fit for workshop environments

Offered in a workshop execution, this pin is engineered for daily use on production and service benches. The robust finish and simple single‑pin design permit quick swaps and straightforward inspection sequences, enabling technicians to maintain throughput without compromising measurement integrity. The result is faster control loops and fewer production stops due to uncertain fits.

Where this pin makes the difference

Typical applications include end‑dimension verification, go/no‑go checks in small bore production, and dimensional reference in assembly jigs. The combination of micro‑range geometry, tight tolerance and resilient material makes the pin suitable for precision toolrooms, watch and instrument makers, and quality labs that require repeatable, compact measuring aids without complex handling requirements.
