Gauge pin M323.257 — 2.57 mm, ±0.001 mm accuracy, 50 mm length (Metav IndustryLine)

The Gauge pin M323.257 is a single precision test pin for end‑dimension and fit verification in inspection benches and workshop jigs, designed for fine mechanical and assembly control tasks.

• Precision tolerance ±0.001 mm
• Diameter 2.57 mm for tight fits
• 50 mm length for stable handling
• Workshop version with protective case

Precision that secures assembly tolerances

A precision test pin with a tolerance of ±0.001 mm provides measurably tighter pass/fail criteria than standard workshop pins. The fine 2.57 mm diameter makes this item ideal for checking small bores, pin fits and end masses where even micrometre deviations lead to functional faults. Using such a pin in gauging or end‑of‑line checks reduces rework and rejects by making tolerance verification repeatable and traceable. The compact design supports high measurement cadence in production settings, enabling efficient quality control without complex setup.

Compact format for fine work and repeatable handling

The slender geometry and 50 mm overall length produce a stable feel when inserted into bores or fixtures; the short length limits bending and improves positional repeatability compared with longer probes. At approximately 0.005 kg, the pin is easy to handle and to seat precisely in small components. For inspection benches and manual gauging operations, this format speeds up cycle times while maintaining measurement integrity. The pin functions as a clear go/no‑go reference in assembly processes and is compatible with common inspection jigs used in precision engineering.

Workshop‑ready durability and transport protection

Manufactured from special steel and supplied in a protective case for transport, this workshop execution is built for everyday use in maintenance and production environments. The robust material resists wear during repetitive seating, extending service life and preserving the declared tolerance. Where consistent reference dimensions are required across shifts, the combination of material choice and protective packaging ensures the reference surface remains intact and ready for immediate use. For tailored advice on integrating the pin into existing gauging systems, technical consultants are available to recommend mounting and handling practices.
