Precise reference for reliable inspection results

This inspection pin serves as a compact reference for dimensional controls where repeatability matters. With a certified manufacturing tolerance of ±0.002 mm, the pin delivers consistent positional references for gauges, plug checks and fixture set-ups. The combination of the small form factor and defined diameter makes this part a dependable datum for both manual and semi‑automatic inspection routines, reducing measurement variation and speeding up set‑up.

Robust material and mechanical stability for long service life

Machined from special steel, the pin resists wear and retains geometric integrity under frequent contact and handling. The choice of material supports stable diameters over time, which directly reduces the need for frequent replacements and conserves calibration intervals. Where traceable, repeatable reference points are required on the shop floor, this construction helps to maintain that stability without adding unnecessary complexity.

Practical workshop design that simplifies handling

The workshop specification prioritises ease of use: at 50 mm length and approximately 0.15 kg mass, the component is easy to position yet substantial enough to remain steady in fixtures. Supplied as a single item, the pin is intended for quick installation into test rigs or as a reference in set‑ups. Delivery in a protective transport case ensures the datum faces remain free from transit damage and simplifies storage between uses.

Integration into inspection workflows and fixtures

The pin is suitable for end‑measurement tasks, locating features and as a reference element in comparative checks. Its standardised diameter and compact length enable straightforward incorporation into existing gauge assemblies or bespoke jigs. For applications that require consistent bench references across multiple stations, the combination of defined geometry and workshop durability supports efficient repeatability and process stability.
