Gauge Pin M323.402 — Single 4.02 mm, ±0.001 mm, 50 mm Length (Metav IndustryLine)

A Gauge Pin M323.402 designed for accurate end‑dimension checks and routine workshop inspection tasks

• Workshop version for robust daily use
• Diameter 4.02 mm with ±0.001 mm tolerance
• 50 mm controlled length for end‑dimension checks
• Supplied in protective transport case

Traceable accuracy for end‑dimension control

The plug‑style gauge pin is manufactured to a tight ±0.001 mm tolerance, equivalent to 1 µm, which positions it in the high‑precision class for small‑diameter inspection tools. This level of repeatability is particularly valuable in final inspection stations where marginal dimensional deviations affect assembly fit. The narrow diameter and micro‑tolerance make the component suitable for measuring end‑masses and mating bores, converting a single tactile check into a verifiable measurement step that supports process control and rejects avoidance.

Robust workshop design that eases handling

Constructed from special steel and finished for workshop use, the test pin combines surface stability with practical handling. The 50 mm stem length provides adequate reach for many through‑hole and blind‑bore checks while remaining short enough to avoid excessive bending or handling error typical of longer pins. The compact geometry and clear diameter marking simplify selection in a busy inspection bay, and the protective transport case reduces the risk of damage during storage and transport, preserving the pin’s calibrated condition and surface integrity.

Application scope and process benefits

Classified among the extremely compact inspection tools, this gauge pin suits micro‑measurement tasks within the range of small‑part manufacture and precision assembly. It supports quality workflows by offering a simple, mechanical reference for go/no‑go assessments and dimensional verification during incoming inspection or final control. Integrating the pin into fixture checks or gauge stacks improves throughput by providing a reliable reference that minimises setup time and lowers rework rates, delivering measurable efficiency gains across repetitive inspection routines.
