The JBO Thread Plug Gauge is a go/no-go inspection tool designed for metric coarse threads. It helps engineers, machinists, buyers, and maintenance teams quickly verify threaded holes meet the correct size and pitch, ensuring reliable fitment of components. Crafted from hardened steel for long-lasting performance, this right-hand gauge handles demanding workshop use while maintaining accuracy. Sized for M36 x 4 with a 6G tolerance, it is tailored for standard metric coarse-thread applications.

• Go/No-Go design for fast QC: Two ends provide quick go (fits) and no-go (does not fit) checks, speeding inspection and reducing guesswork.
• Rugged, knurled body for secure handling: Textured exterior ensures a confident grip in busy or challenging environments, helping you maintain precise control.
• Right-hand M36 x 4, 6G metric coarse thread specification: Precision sizing that matches common coarse-thread hardware, delivering consistent, repeatable inspection results.

Using this gauge streamlines quality control, improves installation reliability, and minimizes downtime by enabling clear, decisive thread checks. Its hardened steel construction supports durability across routine use, while the specific M36 x 4, 6G right-hand configuration ensures compatibility with standard metric coarse-thread applications for dependable, long-term performance.
