The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external thread diameters to UNS standards. It’s essential in manufacturing, automotive, and aerospace environments where fast, consistent inspection of right-handed threads matters. The NoGo designation makes it straightforward to identify non-conforming threads and prevent improper fits.

Designed for right-handed threads with a 1 1/16 x 12 size and 2A tolerance, this gauge's NoGo feature enables rapid identification of non-conforming threads, helping ensure proper fitment and performance. It is crafted from hardened steel for durability and long service life.

• NoGo design for quick pass/fail checks: The NoGo feature lets inspectors rapidly confirm whether external threads are within tolerance, enabling immediate rejection of oversize or undersized parts and reducing rework.
• Durable hardened steel construction: Built to withstand daily use in busy shops, resisting wear while maintaining accurate reference surfaces for reliable measurements.
• Precise UNS sizing for common right-hand threads: Sized exactly for 1 1/16 x 12, right-hand threads in the 2A class, providing consistent, repeatable measurements across parts and batches.

In practice, this gauge helps you speed up quality control, reduce rework, and ensure your threaded assemblies fit and function correctly the first time. Its combination of precise UNS sizing, durable materials, and clear NoGo indication makes it a dependable reference on the shop floor, supporting a smoother workflow and reliable results across projects.
