The JBO Thread Ring Gauge (GO) is a precision measuring tool designed to verify external metric threads quickly and reliably. In Metric Fine, Right Hand configuration (M98 x 2) with a compact 6 g design, it helps inspectors, engineers, and machinists confirm that components meet the exact thread size and fit required by standards.

Crafted from hardened steel, this GO thread ring gauge offers exceptional durability and wear resistance for demanding shop environments. Its robust construction helps maintain accuracy over many inspections, reducing the need for frequent replacements and rechecks.

• Accurate metric fine GO standard: Quickly confirms that external threads meet the specified M98 x 2 size, enabling faster acceptance testing and consistent fits across parts.
• Durable hardened steel construction: Built to resist wear in busy workshops, providing long service life and reliable measurements through repetitive use.
• Ergonomic knurled design for easy handling: Knurled outer rim and smooth bore support fast, confident alignment and minimal setup time during inspections.

This GO thread ring gauge helps you streamline quality control by delivering clear, repeatable results for each part’s external threads. It supports tighter tolerances, reduces inspection time, and enhances workflow reliability from incoming inspection through final assembly.
