The JBO Thread Ring Gauge (GO) - UNC - Right Hand - 2A - 1 1/2 x 6 is a precision tool designed to verify external threads on fasteners, fittings, and machined components. Built for engineers, machinists, quality teams, and maintenance staff, it delivers quick, reliable checks to confirm parts meet UNC standards.

Designed for durability and accuracy in busy workshops, this GO ring gauge helps you quickly determine whether a part’s external thread diameter conforms to the 1 1/2 x 6 UNC right-hand specification, supporting efficient quality-control workflows and reducing rework.

• Go/No-Go UNC verification: Provides immediate pass/fail feedback for external UNC threads, enabling fast, confident decisions and streamlined inspections without guesswork.
• Hardened steel construction: Built from hardened steel to resist wear and maintain precise dimensions through many measurement cycles in demanding environments.
• Right Hand, 2A tolerance class design: Engineered to the standard UNC right-hand 2A specification for repeatable, compatible results with common inspection routines.

In practical use, this gauge speeds inspections, minimizes guesswork, and helps you maintain consistent thread quality across batches. Its rugged build and standard UNC 2A, right-hand dimension make it a dependable, long-lasting addition to any shop or QA lab, delivering reliable results with every measurement.
