The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It helps machinists, inspectors, and assembly teams quickly verify threaded holes for proper fit, ensuring components mate reliably in quality-critical applications.

This Go/No-Go gauge is tailored for M24 x 1.5 metric fine threads, supports left-hand thread configurations, and aligns with the 6H tolerance class. Made from hardened steel, it delivers durable, repeatable measurements that stand up to daily use in busy shops.

• Go/No-Go quick verification: provides clear pass/fail results in seconds, reducing inspection time and guesswork during production and maintenance.
• M24 x 1.5 metric fine-thread compatibility: designed for precise checks of M24 x 1.5 holes, with 6H tolerance and left-hand thread suitability for reliable mating with corresponding fasteners.
• Hardened steel construction: built to resist wear and maintain accuracy through thousands of inspections, lowering replacement costs and downtime.

Use the JBO Thread Plug Gauge to accelerate quality checks, improve assembly reliability, and maintain consistent results across shifts. Its durable construction and straightforward Go/No-Go inspection help engineers, machinists, and maintenance teams work more efficiently and with greater confidence.
