JBO Thread Plug Gauge - Metric Fine Go/No-Go - Right Hand - 4H - M1.2 x 0.2 is a precision tool designed to verify metric fine-threaded holes quickly and reliably. The Go/No-Go design lets you perform a simple pass/fail check, helping technicians, engineers, buyers, and inspectors confirm parts fit together as intended without guesswork.

Built for real-world use, the gauge is crafted from hardened steel to resist wear and maintain accuracy through busy production runs and frequent inspections. Its right-hand orientation follows standard metric threading conventions, making it a dependable addition to any machining, assembly, or QA workflow.

• Go/No-Go design for quick, decisive checks: Instantly confirm whether a hole meets the M1.2 x 0.2 fine thread spec with a simple pass/fail test, speeding up inspection and reducing guesswork.
• Hardened steel construction for durability: Built to withstand frequent handling and repetitive use while maintaining accurate measurements over time.
• Right-hand metric fine thread compatibility (4H, M1.2 x 0.2): Precisely matched to common metric fine-thread standards, ensuring reliable results and easy integration with other tools and parts.

Using this gauge helps you streamline QA and assembly workflows, cut inspection time, and improve reliability across production lines. With durable construction and precise Go/No-Go action, you’ll reduce rework, ensure consistent fit, and maintain high-quality standards from first part to last.
