Test Pin M323.520 — precision Ø 5.20 mm, ±0.001 mm

The Test Pin M323.520 is a single precision measuring probe for end‑dimension checks and reference measurements in workshop metrology

• Workshop version, robust construction
• Diameter 5.20 mm with ±0.001 mm accuracy
• Hardened special steel for wear resistance
• Supplied in protective transport case

Reliable reference for end‑dimension inspection

The M323.520 serves as a high‑accuracy reference for end‑dimension checks where repeatability is essential. With a nominal diameter of 5.20 mm and a tolerance of ±0.001 mm, the pin permits micrometric verification of mating bores, gauge seats and turned ends. This level of precision corresponds to a one‑micrometre tolerance band, which reduces uncertainty in pass/fail decisions and speeds up QC routines by providing an unequivocal mechanical reference without complex interpretation. The compact geometry and defined contact area also limit measurement variability caused by seating or angular misalignment.

Built for workshop use and secure handling

Designed as a workshop execution, the probe combines special steel hardness with a straight 50 mm shank for sturdy, repeatable placement in fixtures or test jigs. The 50 mm length gives sufficient reach for many end‑dimension tasks while remaining easy to handle during series checks. Supplied in a protective transport case, the pin arrives ready for safe storage and transport, reducing the risk of damage and maintaining calibration integrity between uses. The light mass supports quick manual handling and rapid insertion into gauges without introducing appreciable deflection.

Fits micro‑measurement workflows and assembly checks

Classified in the Micro range for compact measuring tools, this test pin is ideal where space is limited and fine mechanical components demand tight tolerances. Its dimensions and accuracy make it suitable for use in incoming inspection, fixture validation and final assembly checks of small parts. The robust material choice provides long service life under repeated contact, lowering lifecycle costs by extending intervals between replacements. Integration into standard inspection tables or bespoke holders is straightforward because the geometry follows conventional probe proportions.
