The JBO Thread Plug Gauge is a precision right‑hand Go/No‑Go gauge sized for M20 x 1.5 threads, designed to quickly verify threaded holes and electrical conduit fittings to the 7H tolerance. Its compact, dual‑ended design provides fast, decisive pass/fail feedback, helping inspectors and machinists confirm conformance without guesswork. Ideal for manufacturing, automotive, aerospace, and electrical conduit applications, it supports reliable setup and quality control across critical threaded connections.

• Dual‑End Go/No‑Go Design: Quickly validate that a thread is within specification—one end confirms proper engagement (Go) and the other end detects out‑of‑tolerance fit (No‑Go), reducing inspection time and avoiding costly rework.
• Precise M20 x 1.5 Right‑Hand, 7H Tolerance: Engineered to align with common conduit and threaded‑hole specs so you can trust measurements reflect true conformance and fit for reliable assemblies.
• Ergonomic, Compact Construction: Knurled, easy‑to‑hold body and a small footprint let you perform checks with one hand in busy work environments, improving speed and accuracy.

This gauge helps streamline measurement workflows by delivering clear, immediate pass/fail results for each threaded part, enabling faster decisions, reducing rework, and improving overall assembly reliability. With consistent checks against the M20 x 1.5 7H standard, you can trust that every conduit fitting or threaded hole will fit as intended, enhancing quality control, reducing downtime, and supporting efficient production or field service.
