JBO Thread Plug Gauge (GO) for UNS is a precision go gauge designed to verify threaded holes against Unified thread standards. Sized for right-hand threads at 1 3/4 x 12 with a 2B tolerance, this tool is essential for machinists, inspectors, and assembly teams working in manufacturing, automotive, and aerospace environments.

Whether you’re setting up setups, performing incoming inspections, or validating post-process threads, this GO gauge provides a clear, rapid indication of proper thread conformance. Its go-end quickly confirms minimum engagement, helping you maintain consistent fit and function across parts and assemblies.

• Go-Thread Verification for Fast Pass/Fail: The go end inserts into a threaded hole to confirm minimum engagement and proper thread depth, delivering a clear, quick indication of conformity and speeding up QC checks.
• Exactly Sized UNS Go Gauge (1-3/4 x 12 Right-Hand, 2B): Precisely matches the external thread standard you need, helping ensure your holes meet spec for reliable assembly with minimal guesswork.
• Rugged, Shop-Ready Construction: Built for repeated use in demanding environments, delivering consistent results and reducing downtime during inspections.

This gauge helps you confirm hole quality early in the production cycle, reducing the risk of assembly issues and rework. By providing a straightforward go/no-go check, it improves workflow, speeds setup, and supports reliable, repeatable results across parts and assemblies that rely on precise threads.
