The JBO Thread Ring Gauge (GO) – UNS – Right Hand – 2A – 1 7/8 x 12 is a precision go gauge designed to verify external thread diameters with exacting accuracy. It helps manufacturers, engineers, and quality teams quickly determine whether threaded components conform to the required standards, supporting consistent fit and reliable assembly across jobs.

Crafted from hardened steel, this GO ring gauge offers exceptional durability and wear resistance for daily use in busy shops and production lines. Its precise geometry ensures repeatable checks, even after repeated insertions and removals, helping you reduce rework and avoid incorrect parts moving forward.

• Precise external thread verification: Quickly confirm that external threads meet the GO limit for the specified UNS 1 7/8 x 12 size, streamlining inspection and reducing guesswork.
• Durable hardened steel construction: Built to resist wear, maintain dimensional stability, and deliver long service life in demanding work environments.
• User-friendly design for fast, confident checks: Intuitive handling helps operators identify conforming parts at a glance, speeding inspections and supporting quality control processes.

This GO ring gauge helps you tighten quality control, improve workflow, and minimize downtime by providing fast, reliable pass/fail results. With its robust construction and reliable accuracy, you can trust it to support precise assembly, reduce scrap, and keep production throughput steady across shifts.
