Gauge pin M323.591 — inspection pin, Ø 5.91 mm, ±0.001 mm (Metav IndustryLine)

Gauge pin M323.591 is a precision-ground inspection pin intended for workshop measurement and dimensional verification in production and quality assurance environments.

• Workshop version for robust use
• Diameter 5.91 mm with ±0.001 mm accuracy
• Precision-ground surface for reliable fit
• Compact 50 mm length for stable positioning

Micron-level accuracy that prevents rework

The inspection pin delivers ±0.001 mm accuracy (equivalent to 1 µm), providing an objective reference for bore and hole checks where small deviations matter. Built with a nominal diameter of 5.91 mm, the pin is ground to tight tolerance and finished to provide repeatable contact geometry; this reduces the need for iterative adjustments during set-up and lowers scrap rates. The combination of fine tolerance and a short, rigid profile supports consistent alignment and verification in serial checks.

Robust workshop design for everyday use

Designed as a workshop version, the pin balances precision with durability. Manufactured from special steel, the component resists wear during repetitive insertions and is suited to routine inspection tasks on the shop floor. Its 50 mm length gives sufficient engagement for secure seating in jigs and fixtures while keeping the effective cantilever low, which helps preserve measurement integrity and improves handling in confined set-ups.

Practical integration into quality workflows

As a single-piece inspection tool, the pin is ideal for quick go/no-go verifications, alignment controls and end-mass checks in assembly operations. The precision-ground finish ensures stable seating and reduces measurement scatter, which speeds up throughput and supports statistical process control. Supplied under the Metav IndustryLine portfolio, the product benefits from a European quality filter and straightforward availability for maintenance spares or measurement kits.
