Description
The JBO Thread Plug Gauge (GO) is a precision tool designed to quickly verify UNC-threaded holes for correct fit. Ideal for manufacturing, automotive, and aerospace environments, it helps ensure threaded components meet Unified thread standards and specifications, reducing rework and returns.
Sized at 1 3/4 x 5 with a right-hand orientation and 2B tolerance, this GO gauge delivers consistent, reliable inspections. Its No-Go design enables rapid identification of non-conforming threads, helping quality teams uncover issues early in the manufacturing process.
- Go gauge for UNC threads: Quickly confirms that holes conform to Unified Coarse (UNC) thread standards, speeding up acceptance checks and reducing guesswork on the shop floor.
- No-Go design for rapid conformance checks: The integrated No-Go feature allows immediate detection of out-of-spec threads, enabling fast rejections and preventing improper fittings.
- Precise size and tolerance (Right Hand, 2B): Designed for consistent, repeatable results with a right-hand orientation and 2B tolerance class, supporting reliable measurements across production runs.
Using this gauge, you streamline quality control workflows, improve part-to-part consistency, and reduce downtime caused by thread mismatches. Its precise dimensions and UNC compatibility make it a dependable addition to inspection routines in manufacturing, automotive, and aerospace applications.
