The JBO Thread Ring Gauge (NoGo) is a precision tool for assessing external UNF threads. Sized for 3/4 x 16 right-hand, 3A class, it helps engineers, inspectors, and machinists verify thread diameters meet Unified thread standards quickly and reliably. Its NoGo design makes non-conforming threads easy to spot, reducing guesswork and speeding inspections.

• NoGo Design for Quick Conformance: Instantly identify out-of-spec threads with a simple ring check, speeding quality control and preventing improper assemblies.
• UNF Right-Hand 3A Dimension Verification: Precisely sized for 3/4 x 16 UNF right-hand threads to confirm external diameters align with Unified thread standards for reliable fitment.
• Hardened Steel Construction for Longevity: Crafted from hardened steel to resist wear in busy workshop environments, maintaining accuracy through repeated use.

This gauge empowers your shop to deliver consistent, accurate thread checks, streamline inspection workflows, and ensure components mate correctly in assemblies, reducing downtime and rework.
