Gauge pin M323.371 — Ø 3.71 mm, ±0.001 mm, length 50 mm (Metav IndustryLine)

The Gauge pin M323.371 is a single precision test pin for end‑dimension verification and alignment in workshop metrology.

• Precision tolerance ±0.001 mm
• Diameter 3.71 mm for end‑measurements
• Workshop version, length 50 mm

Micrometre‑level accuracy that reduces rework and uncertainty

A designation of ±0.001 mm places this test pin in the realm of micrometre‑accurate tools, making it suitable where reliable end‑dimension control is required. The fine tolerance minimises measurement scatter during repetitive checks and supports consistent assembly fits; in practice, using a measuring pin with this specification reduces inspection cycles caused by ambiguous fits and lowers the risk of costly rework. The compact geometry of the pin keeps thermal mass low, which helps preserve accuracy during routine use.

Robust construction for daily workshop inspection

Built as a workshop version, this single test pin combines a small footprint with a serviceable mechanical design suitable for regular handling. The special steel material provides wear resistance and surface stability under contact inspection, ensuring the contacting surfaces retain their geometry over many cycles. At 50 mm overall length the pin balances reach and rigidity, simplifying end‑dimension checks and alignment tasks on small components without excess flex or handling complexity.

Practical application: end‑mass checks and alignment tasks

Designed for end‑dimension verification and fitting operations, this measuring pin performs reliably in tasks such as locating, gauging bores, and verifying assembly end‑masses. The slim 3.71 mm diameter is appropriate for precision dowel and bore checks in small assemblies and jig set‑ups. Integration into a routine inspection workflow is straightforward: label and store the pin with simple procedures, use a calibrated bench comparator if quantitative traceability is needed, and note the SKU for tool control and inventory tracking.
