M323.394 — Gauge pin, 3.94 mm diameter, ±0.001 mm tolerance (50 mm length)

The M323.394 is a workshop-grade gauge pin designed for precise end‑measurements and fixture checks in metalworking and inspection environments.

High precision ±0.001 mm tolerance
Diameter 3.94 mm for accurate end measurements
Supplied in protective transport box

Repeatable, measurable precision for inspection workflows

The M323.394 delivers ±0.001 mm repeatability in a compact format, making it suitable for tight‑tolerance end‑measurements and go/no‑go verifications. The extremely fine tolerance translates into reliable reference points when setting up jigs or validating bore sizes, reducing rework and streamlining inspection routines. As a hard‑wearing reference element, this precision pin supports consistent dimensional control across serial checks and short production runs, improving throughput without compromising measurement confidence.

Robust, workshop‑ready design reduces handling concerns

Manufactured from special steel, the pin is engineered for everyday use in workshop environments where resistance to wear and stable geometry are essential. The 50 mm length and precise diameter ensure a good balance between reach and rigidity, while the low mass supports easy handling during repetitive checks. The workshop execution emphasises practical durability and straightforward integration into existing test benches or plug‑gauge fixtures, so the component remains dimensionally stable even under frequent use.

Practical versatility for inspection and setup tasks

This precision pin serves as a versatile tool for end‑face checks, alignment aids and fixture set‑up. Its narrow 3.94 mm diameter allows access to smaller bores and locating features, while the tight tolerance makes it suitable as a reference gauge in comparative measurements. Where fast, repeatable verification is required—such as incoming inspection or in‑process checks—the pin reduces cycle time by providing an instant, traceable reference without elaborate measurement setups.

Protected delivery and traceability for workshop logistics

Supplied in a protective transport box, the pin arrives ready for safe storage and immediate use, reducing the risk of damage during transit. The product is traceable via its SKU and GTIN, which supports stock management and quality records in professional workshops. Metav’s quality filter and European distribution ensure dependable availability and straightforward replenishment for maintenance of inspection inventories.
