The JBO Thread Plug Gauge is a precision inspection tool designed for metric coarse threads. It enables go/no-go checks of threaded holes, helping ensure proper fit and function across assemblies. Ideal for machinists, inspectors, and manufacturing teams, this gauge delivers fast, reliable verification without guesswork.

Built from hardened steel for long-lasting accuracy, it tolerates heavy use in busy shops. The gauge is configured for right-hand threads with M16 x 2 sizing and a 6H tolerance, ensuring compatibility with standard components and consistent quality checks.

• Go/No-Go Verification: Quickly confirm hole size and thread engagement with clear pass/fail results, speeding up quality checks and reducing guesswork.
• Hardened Steel Durability: Built to withstand repeated use in busy workshops, maintaining accuracy and long service life even under demanding conditions.
• Standard Metric Coarse (M16 x 2), Right-Hand, 6H: Precisely sized to industry standards, ensuring reliable checks of coarse-threaded holes across parts and assemblies.

With the JBO Thread Plug Gauge, quality checks become faster, more consistent, and less error-prone. Inspect threaded holes at a glance, verify fitment during assembly, and reduce rework by catching mismatches early. The durable hardened steel construction means fewer replacements and less downtime, while the Go/No-Go method provides clear, actionable results that you can trust across teams and shifts.
