The JBO Thread Plug Gauge (GO) is a precision tool designed to verify internal threads in metalwork and mechanical assemblies. This GO gauge is specifically tailored for metric fine threads, M56 x 4, right-hand orientation, making it ideal for quality control, inspection, and fit-check tasks across manufacturing environments.

Crafted from hardened steel, the GO gauge delivers long-lasting durability and wear resistance even in busy workshops. Its exact dimensions and easy-to-identify form help technicians quickly confirm whether threaded holes meet the required 6H internal thread tolerance and standards.

• Go gauge for M56 x 4 Right-Hand Threads: Quickly verify hole size and pitch to ensure proper fit and consistent results during inspection.
• Hardened steel construction: Delivers exceptional durability and wear resistance for long service life in demanding environments.
• Metric Fine with 6H tolerance: Designed to match precision internal thread standards, ensuring compatibility with standard components and repeatable inspections.

With the JBO Thread Plug Gauge, your team can streamline threaded-hole inspections, reduce rework, and maintain consistent quality across batches. The reliable, durable design supports fast, accurate go-no-go checks, helping you meet standards and deliver precise assemblies with confidence.
