Designed for metric fine threads, the JBO Thread Plug Gauge checks internal threads for M2.5 x 0.25 with a right-hand orientation and 4H tolerance. Its compact, rugged form fits in any toolbox, and the knurled body provides a secure grip even when wearing gloves. Color-coded end caps aid quick orientation, while the hardened steel construction ensures lasting accuracy and wear resistance in daily shop use.

• Go/No-Go quick verification: Effortlessly confirm whether the M2.5 x 0.25 hole accepts the plug to the correct depth and tolerance, ensuring consistent fits and reducing rework.
• Hardened steel for long life: Rugged construction resists wear in demanding environments, maintaining accuracy after repeated use in inspection tasks and assembly.
• Ergonomic, color-coded orientation: knurled grip plus color-coded end caps enable secure handling, fast orientation, and minimal setup time.

By combining fast inspection, durable build, and easy handling, the gauge helps you speed up quality checks, reduce rework, and achieve consistent thread fits in production, maintenance, and assembly tasks.
