Micro-range precision that shortens inspection loops

Classified as a micro-range gauge (suitable for maximum measuring ranges between 10 and 100 mm), this pin offers a compact solution where tight spatial constraints demand high fidelity. The specified diameter of 12.21 mm combined with an accuracy of ±0.002 mm means repeatable contact points for end measurements, reducing measurement scatter and lowering scrap rates. Explaining the figure: ±0.002 mm corresponds to two micrometres of allowable deviation, a level of precision that supports fine mechanical assemblies and critical go/no-go checks without resorting to bulkier instruments.

Robust workshop design for repeatable handling

The workshop version is built from special steel, giving wear resistance and dimensional stability under frequent use. At 50 mm overall length and approx. 0.10 kg mass, the pin is easy to handle and seats reliably in fixtures or comparison stands; the compact footprint helps maintain measuring force consistency and minimises operator-induced variation. Supplied in a transport box, the gauge is protected during storage and transit, which preserves surface integrity and ensures the nominal diameter is maintained between uses.

Fits inspection routines and simplifies tooling checks

As a single, dedicated end-measurement pin, this item integrates smoothly into routine checks, fixture set-ups and batch sampling. The compact form factor and consistent contact geometry make it a convenient reference for verifying bore stops, setting plug gauges or confirming final dimensions on assemblies. Traceability is supported by clear identification (SKU M323.C21 and GTIN), aiding documentation in quality records and inventory systems. The combination of repeatability and workshop-oriented durability speeds up inspection cycles while maintaining the confidence needed for production decisions.
