Gauge pin M323.395 — 3.95 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

Gauge pin M323.395 is a single precision gauge pin designed for end-measurements and bore inspection in workshop and production metrology.

• Single gauge pin 3.95 mm nominal size
• Ultra-fine tolerance ±0.001 mm
• 50 mm overall length for deep reaches
• Workshop-grade special steel construction

Reproducible results through micrometre-level accuracy

The M323.395 is engineered for tasks where repeatability matters: a nominal diameter of 3.95 mm combined with a declared ±0.001 mm tolerance provides a stable reference for dimensional checks and final inspection. Such a tight tolerance reduces measurement uncertainty during end-measurement routines and supports process control activities in precision assemblies. The fine nominal size and close tolerance make this pin especially valuable when small bore fits or fine positional references are required, helping to shorten inspection cycles and improve result comparability between operators.

Robust, workshop-ready construction for everyday metrology

Built as a workshop-grade instrument, the inspection pin benefits from a compact form factor and a material choice of special steel that balances hardness with wear resistance for regular use. The 50 mm overall length permits access into recessed bores and cavities while maintaining handling comfort for single-handed use. In busy production environments the combination of a slim profile and durable material means the tool resists distortion and preserves its functional geometry under routine handling, thereby extending service life and maintaining measurement integrity.

Practical routines and integration into inspection workflows

As a single precision plug, the pin serves as a tactile reference for bore checks, alignment verification and comparative gauging where visual or optical methods are impractical. It can be used as a reference pin in fixture set-up or as a direct transfer standard for end-of-line checks. Operators benefit from unobstructed access when measuring internal diameters or verifying seatings; the pin’s simple geometry reduces error sources associated with complex probe shapes and facilitates quick go/no-go assessments when combined with complementary measuring devices.
