Gauge Pin M323.401 — Workshop-grade precision pin, 4.01 mm, ±0.001 mm

M323.401 is a precision gauge pin intended for end‑measure and reference checks in workshop and inspection environments, designed as a compact, high‑accuracy measurement standard

• ±0.001 mm calibration accuracy
• Diameter 4.01 mm for tight fits
• Length 50 mm, robust workshop design
• Manufactured from special steel for longevity

Precision where small tolerances matter

The M323.401 gauge pin delivers a guaranteed ±0.001 mm tolerance that supports high‑confidence go/no‑go assessment and reference measurements. This level of precision reduces measurement uncertainty when checking bores, dowel seats or mating components and is particularly valuable where repeatability affects assembly quality. The fine tolerance is achieved through controlled production and finish processes, ensuring each pin serves as a stable measurement standard during repetitive checks.

Compact geometry for dependable handling

A 4.01 mm diameter paired with a 50 mm overall length provides a balance between reach and rigidity for many workshop tasks. The compact geometry reduces lever effects during insertion and withdrawal, which improves repeatability and lessens the influence of operator handling. The workshop execution makes the pin simple to seat and retrieve, enabling faster inspection cycles and consistent end‑measure readings in production or maintenance settings.

Durable material and workshop suitability

Constructed from special steel, the pin resists surface wear and maintains dimensional integrity across repeated use. The material choice supports longevity under normal workshop conditions and helps preserve the calibrated tolerance over time. As a single precision pin, it is ideal for use as a master gauge, reference tool in fixture set‑up or as a verification element in assembly control, offering straightforward integration into existing quality routines.
