The JBO Thread Ring Gauge (GO) - UNEF - Right Hand - 2A - 1 7/16 x 18 is a precision check tool designed to ensure external threads meet exact specifications. Ideal for engineers, machinists, quality control technicians, and workshop personnel, it provides a quick go/no-go test to verify that threaded components conform to the UNEF standard.

Built for reliability in busy production environments, this GO gauge features hardened steel construction for long-lasting wear resistance and consistent performance across shifts. Its straightforward design helps users rapidly identify properly conformed threads, supporting efficient inspection and quality assurance workflows.

• Precise external-thread verification: Delivers quick, direct confirmation that parts meet the UNEF 1 7/16 x 18 right-hand 2A specification, speeding clearance decisions at the inspection bench.
• Durable hardened steel construction: Designed to withstand daily use in demanding environments, resisting wear and maintaining accuracy over time.
• Easy pass/fail inspection: Clear, user-friendly indication simplifies quality control, reducing downtime and enabling faster throughput.

With the JBO GO gauge, your team gains a reliable, fast way to validate thread fit before assembly or mating with components. It streamlines inspection routines, minimizes rework, and supports consistent results across parts and operators—helping you keep projects on schedule and maintain high-quality standards.
