The JBO Thread Plug Gauge is a UNEF Go-No-Go tool designed for precise verification of internal threads in right-hand configurations. Sized for 1 1/16 x 18 with a 2B tolerance, it provides a reliable way to confirm that threaded holes meet Unified thread standards without guesswork. This gauge is ideal for professionals in manufacturing, automotive, aerospace, and maintenance who need consistent, fast thread acceptance testing.

Engineers, machinists, inspectors, and buyers benefit from its straightforward use: quickly determine if a hole is within spec or if it requires rework, helping keep assemblies' reliability and performance intact. Its robust design makes it a practical addition to any shop’s calibration and quality-control toolkit.

• Go/No-Go design for rapid conformance testing: Quickly identify whether threads are within specification, reducing inspection time and preventing improper fittings.
• Precise UNEF sizing (1 1/16 x 18, 2B): Directly checks common UNEF thread sizes with class 2B tolerance, ensuring accurate fit verification with minimal downtime.
• Durable, ergonomic build: Knurled grip and dual-ended threaded ends provide secure handling and versatile setup for busy shop environments, built to withstand daily use.

Using this gauge helps streamline quality workflows, cut rework, and ensure that threaded components will assemble correctly the first time. Its durable construction and clear go/no-go feedback support consistent results across teams, boosting confidence in every measurement and every production run.
