M323.401 gauge pin, 4.01 mm — Workshop test pin with ±0.001 mm accuracy (Metav IndustryLine)

The M323.401 gauge pin is a workshop-grade test pin intended for precise dimensional checks and fixture verification in production and inspection environments.

• Workshop-grade construction
• Diameter 4.01 mm, tolerance ±0.001 mm
• 50 mm hardened special steel
• Supplied in protective transport case

Dependable accuracy for routine inspection

The gauge pin offers ±0.001 mm tolerance, delivering a level of precision suitable for critical inspection tasks and fine adjustment of jigs and fixtures. Such a narrow tolerance reduces measurement uncertainty and supports consistent quality control across batches. Where repeatable go/no‑go verification is required, the pin’s nominal 4.01 mm diameter provides a clear reference that simplifies pass/fail decisions and shortens inspection cycles, improving throughput without compromising traceability.

Built for continual workshop use

Manufactured from special steel and produced in a workshop specification, the pin balances surface hardness with resistance to chipping under frequent insertion and withdrawal. The 50 mm length provides sufficient engagement for many fixture and bore checks while remaining compact and easy to handle at the bench. The robust material choice and finish reduce wear, so calibration drift is minimised and replacement intervals are extended — a practical cost advantage in everyday production.

Practical handling and storage

Delivered as a single gauge pin and packed in a protective transport case, the component is protected during storage and transit, helping to preserve its sensitive tolerance. The modest mass contributes to easy manipulation during repetitive tests and quick set‑up when changing inspection points. The compact format also facilitates organised storage alongside other measuring tools, supporting orderly workflows on the shop floor and in measurement rooms.

How this supports efficient production

Using a precisely manufactured gauge pin for end‑dimension checks removes ambiguity from go/no‑go decisions and reduces rework caused by marginal fits. The simple geometry of the pin permits rapid verification of bores, locating holes and fixture alignment without complex instrumentation, enabling operators to maintain steady output with reliable quality feedback. Combined with Metav’s logistics and product range, the pin helps maintain continuous supply for inspection stations.
