Description
The JBO Thread Ring Gauge (GO) is a precision tool designed to quickly verify external thread diameters on electrical conduit fittings and other right-hand threaded components. Sized for M63 x 1.5 and 8g, this GO gauge helps inspectors, machinists, and assembly teams confirm parts meet the required thread dimensions and standards.
Crafted from hardened steel for durability and long life, it features a knurled outer edge for secure, comfortable handling during routine inspections. The gauge supports efficient verification of threaded components against Unified thread standards, and its no-go design makes non-conforming threads easy to spot at a glance, helping maintain consistent quality in demanding environments.
- Precise GO verification for M63 x 1.5 external threads: Quickly confirms whether a part’s external thread diameter fits within the specified tolerance, enabling fast pass/fail decisions for conduit fittings and other right‑hand threaded components.
- Hardened steel construction with knurled grip: Built to endure daily workshop use with a secure, comfortable grip that reduces slips and improves measurement consistency.
- No-Go verification for identifying non-conforming threads: The integrated no-go capability helps you quickly identify parts that do not meet tolerance, reducing misfits and rework in quality control processes.
Using the JBO Thread Ring Gauge GO streamlines quality checks across manufacturing, automotive, and aerospace applications. It supports faster setup, more reliable inspections, and confidence that conduit fittings and similar components will thread correctly the first time, helping your team maintain high standards and keep production moving.
