The JBO Thread Plug Gauge is a precision go/no-go inspection tool engineered for BSF right-hand threads. Sized for 7/32 x 28, it enables fast, reliable checks of threaded holes and plugs to verify they meet the intended size and pitch.

With its medium-class tolerance, this gauge delivers clear conformance results in today’s workshop environments, helping teams streamline quality checks in manufacturing, automotive, and aerospace applications.

• Go/No-Go Verification for Quick Conformance: The go/no-go design provides a clear pass/fail indication, speeding thread checks and reducing guesswork during inspection.
• Precise BSF Right-Hand Sizing (7/32 x 28): Tolerances aligned with the medium class to ensure consistent measurements and reliable fit across parts and assemblies.
• Rugged, Comfortable Construction: Knurled body with durable metal ends offers secure handling and long service life in busy shop environments.

This gauge helps you accelerate inspections, minimize downtime, and improve overall assembly reliability by delivering precise, repeatable thread checks at the point of use. Its robust design supports daily use in demanding settings, giving you confidence that threaded components will thread in smoothly and meet quality standards.
