Gauge pin M323.310 — Metav IndustryLine precision gauge pin, Ø 3.10 mm, ±0.001 mm

The Gauge pin M323.310 is a compact, workshop‑grade measuring pin designed for precise diameter checks and end‑size verification in production and quality‑control environments.

• Workshop-grade construction
• Diameter 3.10 mm, tolerance ±0.001 mm
• Length 50 mm for depth reach
• Special steel for dimensional stability

Precision that reduces rework and inspection time

The core benefit of this measuring element is its ±0.001 mm tolerance, corresponding to a one‑micrometre class of accuracy that supports tight inspection limits. Such fine limits make the pin suitable for end‑measure checks, reference gauges and comparative testing where repeatability is essential. The small nominal diameter (3.10 mm) and the high accuracy mean fewer ambiguous readings, simplifying decision chains in incoming inspection and short‑run production. By specifying a single, traceable reference piece the inspection routine is shortened and process capability assessments become more consistent.

Robust design for repeatable contact and handling

Constructed from special steel, this workshop variant prioritises dimensional stability and resistance to daily handling. The 50 mm shaft length offers adequate reach for shallow bores and through‑holes without compromising control during alignment, while the low mass supports quick manual manipulation on the shop floor. The pinned geometry and fine tolerance produce a defined contact area that minimises measurement scatter when paired with bench micrometres, gauge blocks or dial indicators. This ruggedness preserves the calibrated condition over repeated use and reduces the frequency of recalibration cycles.

Practical integration into inspection workflows

The pin integrates easily into established metrology procedures: identify the reference, secure the workpiece, and compare runouts or bore diameters against the reference diameter for pass/fail decisions. Traceability is supported through the clear article identification and catalogue references, enabling orderly stock management for small parts inspection sets. Should uncertainties arise regarding fit‑up or specific application requirements, Metav’s advisory service can provide guidance on pairing the pin with appropriate fixtures and measurement devices to ensure reproducible results.
