Gauge pin M323.839 — single precision gauge pin, Ø 8.39 mm, ±0.001 mm (Metav IndustryLine)

A gauge pin M323.839 designed for precise checking of bores, end dimensions and plug-fit inspection in workshop and inspection environments

• ±0.001 mm tolerance
• Diameter 8.39 mm precision
• Length 50 mm workshop version
• Delivered in protective case

High-precision measurement for reliable inspection

The measuring element delivers an exceptional ±0.001 mm tolerance, making this gauge pin suitable where micrometric repeatability is required. The very fine tolerance reduces ambiguity in go/no-go checks and improves process control in batch inspections, which results in fewer rework cycles and faster decision times on the shop floor. The compact geometry and mass distribution also reduce the effect of handling errors, ensuring that each insertion provides a clear, binary assessment of fit.

Workshop-hardened construction for daily use

Manufactured from special steel, the pin is executed as a workshop version that balances wear resistance and dimensional stability. The 50 mm shank length and turned diameter of 8.39 mm give a robust contact area while remaining easy to handle during repetitive tasks. This construction supports sustained use in production environments, where frequent insertion and extraction demand a material that resists surface degradation and maintains the specified tolerance over time.

Practical protection and traceability for quality systems

Supplied in a protective case, the measuring pin arrives ready for safe storage and transport, reducing the risk of accidental damage before first use. The compact packaging eases organisation of inspection kits and supports traceability during audits. For metrology routines that require documentation, the gauge pin’s specifications and labelling integrate smoothly into quality records and work instructions, aiding compliance and reproducibility across shifts.
