Crafted from hardened steel, this gauge is built to withstand daily workshop use and deliver long-lasting performance. The knurled body offers a secure grip for confident handling and precise alignment during inspection.

• Go/No-Go Dual-Ended Design: Quickly verify M11 x 1.5 coarse threads in a single pass—one end confirms the minimum fit (Go) while the other ensures it won’t exceed the maximum (No-Go), speeding inspections and improving consistency.
• Hardened Steel Construction: Rugged, wear-resistant material that stands up to frequent use in busy shops, maintaining accuracy and reducing replacement costs over time.
• Ergonomic Knurled Handle: Secure, comfortable grip for precise alignment and reduced hand fatigue during repeated checks, even in tight or awkward workspaces.

Effortless, repeatable thread verification translates to faster assemblies, fewer threading errors, and higher overall quality. The JBO Thread Plug Gauge delivers dependable performance for engineers, machinists, maintenance technicians, and hobbyists who need accurate, durable tools to confirm hole readiness for metric coarse threads like M11 x 1.5—all with straightforward Go/No-Go checks you can trust.
