The JBO Thread Plug Gauge is a precision tool for metric fine threads. Built for right-hand M18 x 2 applications with a 6G tolerance, it enables fast Go/No-Go checks to confirm threaded holes fit correctly before assembly.

• Go/No-Go simplicity: Quickly determine pass/fail for threaded holes, speeding up inspections and reducing rework.
• Hardened steel durability: Rugged, wear-resistant construction designed to withstand regular use in busy workshops while maintaining accuracy.
• Metric fine-thread compatibility (M18 x 2, Right Hand, 6G): Precisely matched to the most common fine-thread holes, delivering consistent, reliable readings for critical assemblies.

By using this gauge, inspectors and machinists gain consistent, repeatable results, shorten setup and inspection times, and reduce the risk of misfits in assemblies. Its robust construction ensures reliable performance in demanding environments, helping teams maintain quality across batches.
