Gauge pin M323.I39 – single plug gauge, 18.39 mm diameter, 50 mm length (Metav IndustryLine)

A gauge pin engineered for precise final-size inspection and go/no-go reference measurements in workshop metrology and toolmaking environments.

• Precision 18.39 mm diameter, ±0.002 mm tolerance
• 50 mm length for stable handling and repeatable checks
• Workshop-grade special steel construction
• Supplied as single gauge pin, inspection reference

Engineered for repeatable dimensional checks

The M323.I39 is manufactured to deliver consistent repeatability for bore verification and reference testing. With a nominal diameter of 18.39 mm and a declared tolerance of ±0.002 mm (equivalent to 2 micrometres), the pin provides a measurable boundary for acceptance decisions in quality control routines. The tight tolerance supports reliable pass/fail judgements and reduces uncertainty during serial inspections, making the component suitable for tasks where precision is the decisive criterion.

Practical workshop handling and application benefits

At 50 mm overall length the plug offers a good balance between reach and rigidity, facilitating comfortable handling during in-process checks and bench inspection tasks. The special steel construction is specified for workshop use and provides mechanical stability for repeated contact with bores and housings. Designed as a single, dedicated reference pin, it functions well as an end-size datum for setting fixtures, checking reamed holes or confirming final bore dimensions in assemblies, helping to streamline routine inspection workflows.

Built for quality workflows and dependable supply

Delivered with a focus on everyday usability, this workshop version is intended to integrate into formal measurement procedures or quick verification loops on the shop floor. The declared ±0.002 mm accuracy aligns the component with high-precision acceptance criteria, while the modest weight supports easy handling without adding complexity to test rigs. Metav’s role as a European quality filter and distribution hub ensures consistent product availability and traceability, supporting uninterrupted inspection processes in production and maintenance environments.
