• 50 mm length for recessed and through measurements
• Made from special steel for high wear resistance

Repeatable end‑of‑line measurements with industrial accuracy

The gauge pin offers a simple, reliable way to verify bore sizes and end‑masses. With a nominal diameter of 19.21 mm and a verified positional tolerance of ±0.002 mm, the pin provides a clear go/no‑go reference that reduces decision time during quality checks. The compact geometry and a 50 mm shank length make the pin suitable for both shallow and deeper bores, enabling fast in‑process inspections that cut down on measurement setup and throughput delays.

Built for workshop resilience and easy handling

Constructed in workshop version specification from special steel, the pin tolerates regular use in machine shops and inspection benches. The material choice gives wear resistance and good surface stability, which keeps the reference diameter stable over repeated cycles and minimises the need for frequent replacement. Its single‑piece design simplifies handling and storage; when used with standard inspection fixtures the pin streamlines routine measurements and contributes to predictable process capability.

Traceability, identification and procurement certainty

Identification is straightforward: SKU M323.J21 and GTIN 4061905071829 ensure unambiguous ordering and stock control. The product is listed in the Messstifte category and conforms to industry expectations for gauge pins used in end‑measure verification. Having clearly documented part numbers accelerates reordering and inventory management, supporting uninterrupted operations and consistent quality assurance.
