The JBO Thread Plug Gauge is a precision tool designed to verify metric fine internal threads with speed and reliability. Specifically crafted for right-handed M1.6 x 0.2 threads and a 5H tolerance, this Go/No-Go gauge lets technicians confirm hole readiness quickly and with consistent accuracy.

Built from hardened steel for long-lasting performance, it stands up to daily workshop use and maintains reliable readings through years of inspection and assembly work.

• Go/No-Go efficiency: Quickly determine if a hole accepts the M1.6 x 0.2 thread within the 5H tolerance, enabling fast, confident acceptance testing and reducing guesswork.
• Hardened steel durability: Designed to resist wear and deformation in busy environments, delivering stable measurements and extended tool life.
• Metric fine-thread precision: Specifically matched to metric fine internal threads with a right-hand orientation, ensuring reliable, repeatable checks for common components.

Using this gauge streamlines quality checks, speeds up setup, and helps prevent misfits in production. Its clear go/no-go results support consistent assembly, lower downtime, and improved part-to-part accuracy, giving you confidence in every measurement from incoming inspection to in-process validation.
