The JBO Thread Plug Gauge is a precision inspection tool designed for quick, reliable checks of threaded holes and components. It’s ideal for professionals in manufacturing, automotive, and aerospace who need to verify that threads conform to Unified thread standards with a straightforward go/no-go test. With its Right Hand orientation, 2B tolerance, and 1/4 x 36 size, this gauge delivers clear, repeatable measurements that support efficient quality control and proper fitment in assemblies.

• Go/No-Go quick checks: Instantly determine if threads conform or not by testing both go and no-go limits, speeding inspections and reducing rework.
• Exact UNS 1/4 x 36 size, 2B tolerance: Precise dimensions aligned to Unified thread standards, ensuring reliable hole and thread assessments across parts.
• Ergonomic knurled body for easy handling: Textured grip and solid construction enable secure, comfortable use during long inspection sessions, enhancing accuracy.

Using the JBO Thread Plug Gauge streamlines threaded-hole inspections. The go/no-go approach provides immediate clarity on fit, reducing downtime and rework, while the precise 1/4 x 36 UNS size with 2B tolerance ensures consistent results across parts. Designed for right-hand threads, it integrates smoothly into standard QA workflows, giving engineers, technicians, and buyers confidence in every measurement and helping you maintain quality across production runs.
