Test pin M323.C78 — workshop gauge pin, 12.78 mm Ø, 50 mm length (Metav IndustryLine)

Test pin M323.C78 for end‑dimension verification and reference measurements in workshop inspection and assembly environments.

• Workshop version for robust daily use
• Diameter 12.78 mm for end‑dimension checks
• Tolerance ±0.002 mm for high repeatability
• Supplied in protective transport case

Precision that keeps production within tolerance

The gauge pin is manufactured to a tight ±0.002 mm specification, making it suitable for demanding workshop inspection tasks where reproducible end‑dimension checks are essential. With a nominal 12.78 mm diameter and short 50 mm length the component offers low bending moment and stable contact geometry, enabling fast verification of bores, shafts and fit gauges. This level of precision supports quality control steps and reduces rework by supplying clear, verifiable measurement references.

Built to withstand everyday workshop use

Designed as a workshop version, the pin is made from special steel to combine hardness with dimensional stability under repeated handling. The compact 50 mm form factor and modest mass make the item easy to seat and manoeuvre on inspection benches or in jig fixtures, while the robust material resists typical workshop wear. Supplied in a protective case for secure transport, the item arrives ready to integrate into inspection routines without additional packaging effort.

Practical handling and integration into inspection workflows

The compact gauge pin supports quick plug‑and‑check operations and pairs readily with common bench equipment and handheld comparators. As a plain reference element, it simplifies pass/fail checks and can be used alongside gauge blocks or end‑standards to build traceable control sets. The M323.C78 format is particularly suitable where short reach and high stiffness are required, ensuring consistent seating and minimal operator‑induced variation during repetitive checks.
