Reliable precision that reduces rework and inspection time

Engineered for consistent dimensional checks, this test pin offers a tolerance of ±0.001 mm, which positions it in the high-precision segment for small-diameter end measures. The fine tolerance provides a clear rational advantage in quality control: fewer false rejects, faster go/no-go decisions and a measurable reduction in rework. The ground diameter and tight specification are translated into practical benefits on the shop floor — faster set-ups and stable reference measurements when aligning fixtures or checking bore finishes.

Built for everyday workshop use with durable materials

Manufactured from special steel and labelled as a workshop version, the pin resists wear that would otherwise degrade accuracy over time. The combination of compact size and hardened material means reliable contact behaviour during repeated probing; this improves long-term reproducibility and lowers lifetime cost-per-measure. Supplied in a protective case, the component reaches the bench ready for immediate use and safe transit between workstations, reducing handling risk and preserving the calibrated condition of the gauge.

Practical integration into inspection routines and tooling

As an end-measure tool, the gauge pin supports common inspection tasks such as checking bore diameters, verifying plug fits and confirming mating part tolerances. Its compact length of 50 mm and near-5 mm diameter make it suited to fine mechanical work and small-assembly checks. The clear specification simplifies documentation in incoming inspection reports and maintenance logs, enabling traceable decisions and straightforward replacement planning when multiple pins are held in inventory.
