The JBO Thread Plug Gauge is a precision inspection tool built for fast, reliable verification of threaded holes. Designed for 1/4 x 26 BSF right-hand threads in metal components, it helps manufacturers, automotive shops, and aerospace maintenance teams confirm hole accuracy quickly and consistently.

With its go/no-go design, technicians can instantly determine whether a hole matches the specified thread limits, reducing misfits and rework while keeping production moving. The compact, dual-ended gauge is easy to incorporate into standard inspection routines and quality checks.

• Dual-ended go/no-go design: Quickly verify both the acceptable (go) and minimum (no-go) thread limits in a single check, delivering unambiguous pass/fail results and speeding inspections.
• Precise 1/4 x 26 BSF Right-Hand, Medium Class: Engineered to the exact BSF thread form and medium tolerance, ensuring consistent acceptance or rejection decisions for each hole.
• Rugged, ergonomic construction: Knurled body provides a secure grip and repeatable measurements in busy shops, while robust ends resist wear from routine use.

The JBO Thread Plug Gauge helps you streamline thread inspection, minimize downtime, and improve overall quality. Its straightforward go/no-go feedback enables fast, confident decisions on fitment, while the durable design stands up to daily use in manufacturing, automotive, and aerospace environments. Trustworthy and consistent, it delivers reliable thread verification you can depend on.
