The JBO Thread Plug Gauge is a precision instrument designed for metric fine threads. It helps machinists, quality inspectors, and assembly professionals quickly verify thread conformity in drilled or tapped holes.

Designed for M36 x 2 right-hand threads with a 6G internal tolerance, this Go/No-Go gauge ensures threads meet exact standards, promoting consistent fit and reliable performance in critical assemblies.

• Go/No-Go quick inspections: The Go/No-Go design lets you quickly determine whether a hole’s internal threads meet the specification, reducing guesswork and speeding quality checks.
• Hardened steel construction for durability: Built to resist wear and maintain accuracy through repeated use in demanding workshop environments.
• Right-hand metric fine threading, M36 x 2 (6G): Precisely matched to the M36 x 2 fine-thread standard, ensuring reliable checks and consistent mating with components.

With this gauge, you gain faster, more reliable thread verification that minimizes downtime, reduces rework, and helps ensure every part threads smoothly the first time. Its durable construction supports long-term accuracy, making it a dependable addition to any shop, production line, or repair task where precise metric threads matter.
