The JBO Thread Plug Gauge is a precision tool built for metric fine threads. Specifically designed for right-hand M24 x 1 holes with a 6H tolerance, it makes Go/No-Go checks fast and reliable, helping you confirm that threaded components will mate correctly.

Crafted for durability and everyday workshop use, this gauge uses hardened steel and a knurled body for secure handling. Its robust construction stands up to repeated insertions and inspections, delivering consistent results over time.

• Go/No-Go quick verification: instantly confirms whether a threaded hole meets the M24 x 1 6H specification, reducing guesswork and speeding up assembly checks.
• Hardened steel, durable construction: engineered for long life in demanding shop environments, resisting wear and maintaining accuracy after many uses.
• Right-hand, metric fine thread compatibility: precisely matched to metric fine threads, ensuring reliable gauging of fits and preventing cross-thread issues.

This plug gauge helps you streamline quality control and assembly workflows. By delivering clear pass/fail indications, it minimizes rework, protects component threads from damage during inspection, and supports consistent results across multiple parts or batches. Whether you’re a manufacturing engineer, shop technician, or DIY enthusiast, you gain confidence knowing your threaded connections meet spec on every job.
