The JBO Thread Plug Gauge – UNF Go-No/Go, Right Hand, 2B, No. 0 x 80 – is a compact, high-precision inspection tool designed to verify UNF threads in threaded holes. Ideal for manufacturers, automotive shops, aerospace QA teams, machinists, and quality inspectors, it helps ensure parts meet the Unified thread standards before they move to assembly.

With its go/no-go design, you can quickly determine whether a thread hole conforms to the specification, reducing guesswork and rework. The No. 0 x 80 size and 2B tolerancing deliver reliable, repeatable checks across multiple parts and lots, while the right-hand orientation aligns with common production workflows.

• Go/No-Go quick verification: The go/no-go design allows inspectors to identify conforming versus non-conforming threads at a glance, speeding up acceptance checks and reducing inspection time.
• UNF 2B, No. 0 x 80 sized: Precisely matched to Unified thread standards with 2B tolerances, providing consistent measurements and reliable interchangeability for your threaded components.
• Rugged, knurled construction with compatible ends: Durable grip for secure handling in busy shops and easy plug-in/removal from threaded holes without damage, engineered for long tool life.

This JBO thread plug gauge helps your team maintain strict thread quality, improve workflow, and cut downtime by delivering clear, dependable results. Whether you’re performing incoming inspection, in-process checks, or final assembly, this gauge provides confidence that every threaded hole will accept the intended fastener and perform as designed.
