The JBO Thread Plug Gauge (GO) UNC Right Hand, 2B, 2 1/4 x 4.5 is a precision go gauge designed to verify threaded holes and components quickly and reliably. Sized for UNC 2B class and right-hand threads, it helps manufacturing, automotive, and aerospace teams confirm that threads meet Unified standards and will assemble as intended.

With its Go design, this gauge makes it easy to identify properly formed threads at a glance, accelerating inspection and reducing guesswork during assembly and quality checks.

• Go design for fast pass/fail checks: Quickly confirms whether threads meet spec, speeding inspections and minimizing downtime in high-volume production environments.
• UNC 2B right-hand thread compatibility: Precisely matched to Unified National Coarse standards, ensuring accurate gauging of common threaded holes and parts.
• Durable knurled body for reliable, repeatable use: Rugged construction and textured grip support consistent readings, even with work gloves on and in busy shop conditions.

Using the JBO GO Thread Plug Gauge helps you streamline QA workflows, reduce rework from out-of-tolerance threads, and maintain consistent results across parts and batches. Its straightforward design and durable build give operators confidence in daily gauging tasks, supporting reliable fit and performance in your assemblies.
