Gauge pin M323.394 — 3.94 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

A gauge pin M323.394 designed for precise end‑measurements and reference checks in workshop inspection routines.

• Workshop version with robust construction
• Diameter 3.94 mm with ±0.001 mm accuracy
• 50 mm usable length for compact parts
• Made from special steel for dimensional stability

Accurate reference measurements for tight tolerances

The core advantage of this gauge pin is its ±0.001 mm dimensional tolerance, which provides high repeatability for end‑measurements and reference checks. Such fine accuracy reduces uncertainty when verifying bore sizes, seating surfaces or calibrated fixtures; the tight tolerance converts directly into fewer rework cycles and more reliable quality control data. The compact diameter supports fine inspection tasks while still offering a clear, quantifiable reference against drawing limits.

Durable workshop design that simplifies handling

Constructed from special steel and presented in a workshop version, the pin combines mechanical robustness with a lightweight profile (approx. 0.007 kg) for easy manipulation. The 50 mm length gives sufficient reach for many small components while remaining manageable on the bench; operators benefit from improved posture and quicker placement compared with longer reference rods. The material choice supports long service life under routine use in production and maintenance environments.

Easy integration into inspection and gauging workflows

As a purpose‑built gauge pin, this part serves reliably as a go/no‑go reference, end measure and assembly stop in modular inspection setups. The compact form factor suits micro‑measurement tasks classified in the "Micro" range (max. 10–100 mm), where stiffness and low distortion are essential. Traceable identification is provided via SKU M323.394 and GTIN 4061905056161, enabling clear stock control and integration into inspection documentation and production traceability systems.
