Gauge pin M323.521 — precision test pin, 5.21 mm diameter, ±0.001 mm tolerance (Metav IndustryLine)

The Gauge pin M323.521 is a single precision test pin designed for high-accuracy reference and go/no-go checks in inspection fixtures and jigs.

• ±0.001 mm tolerance
• Diameter 5.21 mm
• Length 50 mm
• Special steel construction

Precision that keeps production on target

This compact test pin offers a tolerance of ±0.001 mm, which makes it suitable for demanding dimensional checks where small deviations matter. The declared 5.21 mm diameter and 50 mm length provide a stable datum for plug gauges, alignment pins and go/no-go fixtures; the combination of these dimensions reduces positional play during repeated insertions. By using a hardened, dimension-stable reference element, measurement uncertainty is limited and inspection throughput improves — a clear rational benefit for batch control and first-article inspections.

Robust workshop design for repeated handling

Made from special steel, the component is engineered for repetitive use in workshop environments. The workshop version indicates a focus on durability and straightforward handling: short mass reduces wear on mating bores and the compact weight (approx. 0.011 kg) simplifies manual placement. The single-item supply format suits operators who need a specific diameter for setup or replacement without buying sets. This robustness lowers the risk of downtime and conveys confidence that the reference pin will resist deformation under normal workshop conditions.

Practical advantages in fixture building and inspection

As a precision reference element, the pin serves both as a locating device and a control gauge. Its narrow tolerance supports precise alignment of small-bore components and repeatable seating in jigs, which in turn shortens setup time and reduces scrap rates. The clear numeric specification and traceable SKU make inventory and traceability simple to manage in toolrooms and quality labs. For engineers who demand predictable behaviour from their reference parts, the measurable specification of this test pin translates directly into fewer calls for adjustment and more consistent production results.
