JBO Thread Plug Gauge is a precision tool designed to verify internal threads in electrical conduit fittings and other threaded holes. Sized for M10 x 1 right-hand threads with a 7H tolerance, this go-no-go gauge helps technicians, engineers, buyers, and hobbyists ensure components meet standard specifications and thread-fit requirements.

Designed for fast, reliable checks, the go/no-go ends provide immediate pass/fail feedback, minimizing guesswork and speeding up inspections on the shop floor, in maintenance, or during assembly. This enables consistent, high-quality results across conduit systems and other threaded parts that rely on Unified thread standards.

• Go/No-Go Design for Quick Conformance: Instantly distinguish between conforming and non-conforming threads, reducing inspection time and keeping production and maintenance workflows moving.
• Precise M10 x 1, 7H Standard Fit: Engineered to exacting Unified thread standards, ensuring reliable acceptance testing of internal threads and proper fit for critical conduit connections.
• Durable, Ergonomic Construction: Knurled grip and robust ends offer comfortable handling in tight spaces while delivering long-lasting performance for daily use.

This gauge helps you verify thread quality efficiently, streamline quality checks, and reduce rework or downtime. By ensuring first-time fit and consistent results, it supports faster assembly, dependable performance in conduit systems, and enhanced confidence across engineering, procurement, and maintenance teams.
