The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for metric fine threads. It is specifically calibrated for M10 x 1.25 right-hand threads with a 4H tolerance, enabling fast and reliable checks of internal threads to ensure proper fit and function.

Built from hardened steel and finished for durability, the gauge features a knurled body for secure handling and distinct end markers that quickly differentiate the Go and No-Go ends. This compact, two-ended design delivers repeatable results in tight spaces and with work gloves, making it ideal for both on-site and shop-floor use.

• Go/No-Go design for rapid thread inspection: Provides immediate pass/fail feedback on internal threads, speeding up quality checks and reducing guesswork in production.
• Metric fine threading: M10 x 1.25, right-hand: Precisely matched to your specific thread size and orientation, helping prevent mismatches and ensuring consistent assembly.
• Hardened steel with knurled grip and color-coded ends: Durable, wear-resistant construction paired with a secure grip and quick-end identification for reliable, everyday use.

This gauge supports efficient quality control by delivering clear, repeatable results that translate to fewer reworks and tighter process control. Its robust build and thoughtful design help you maintain accurate threading checks across batches, contributing to smoother workflows and higher confidence in every assembly.
