Gauge pin M323.641 — 6.41 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The gauge pin M323.641 is a workshop-grade precision plug used for end-dimension verification and go/no-go fitting tasks in production and inspection environments.

• Diameter 6.41 mm with ±0.001 mm tolerance
• Length 50 mm for stable probing and handling
• Manufactured from special steel for durability
• Workshop version for consistent fit and finish

High-precision control for repeatable checks

Engineered for repeatable end-dimension verification, this gauge pin delivers a nominal diameter of 6.41 mm with a certified tolerance of ±0.001 mm, enabling micrometre-class discrimination in tight fits. The narrow tolerance supports objective Go/No-Go assessments and reduces uncertainty during fit checks, which is particularly relevant in small-batch production and incoming inspection. Where traceable repeatability matters, the defined size and minimal runout translate directly into fewer false rejections and steadier process control, supporting leaner quality routines.

Robust material and workshop finish for longevity

Made from special steel with a workshop-grade finish, the probe resists wear in repetitive insertion tasks and retains its diameter tolerance over time. The 50 mm length offers a comfortable working grip and sufficient engagement depth for common fixtures and bores without excessive overhang, improving handling and reducing deflection. At an item weight of 0.016 kg the component is easy to position manually while remaining stiff enough for accurate seating. The combination of material choice and finish reduces surface damage to mating parts and extends in-service life, lowering replacement frequency and total operating cost.

Practical integration into quality workflows

Designed for seamless use in inspection benches and assembly jigs, the pin is suitable for end-dimension checks during final inspection, tooling set‑up and first-article verification. The compact form factor and strict tolerance make it an efficient tool for standardised measurement routines and sampling plans. Marked for traceability with SKU M323.641 and GTIN data, the item can be logged into asset lists or inventory systems to support calibration intervals and quality documentation. Employing such standardised reference sizes helps stabilise statistical process control (SPC) inputs and simplifies audit trails.
