Test pin, single — 3.99 mm Ø, ±0.001 mm (Metav IndustryLine)

The test pin, single serves as a precise check gauge for end‑dimension and fit verification in workshop and bench metrology.

• Sub‑micron accuracy ±0.001 mm
• Diameter 3.99 mm for tight fits
• Robust special‑steel construction
• Compact 50 mm length for confined spaces

Precision that stabilises process control

The compact gauge delivers ±0.001 mm repeatability, making it suitable for fine inspection tasks and final control points in assembly processes. Built for workshop conditions, the component’s special steel body resists dimensional change under normal handling and provides consistent contact behaviour. This accuracy supports faster quality decisions and reduces the need for secondary checks, improving throughput in small‑part production lines.

Designed for fit checks and repeatable end‑measurements

With a nominal diameter of 3.99 mm and a 50 mm overall length, the pin is aimed at tight‑tolerance fit verification and end‑stop measurements. The short, rigid geometry minimises deflection during insertion, so readings remain reproducible across repeated cycles. For fabricators and maintenance teams, this means clearer go/no‑go outcomes and fewer interruptions to production due to ambiguous fits.

Workshop robustness combined with easy integration

Supplied as a single, workshop‑grade test pin, the component combines a hardened contact surface with a slim profile that fits confined fixturing and gauges. The workshop execution and material choice prioritise longevity under frequent use while keeping handling straightforward for inspectors and machinists. Where quick, reliable verification of end dimensions is required, this pin integrates neatly into existing inspection jigs and manual test routines.
