The JBO Thread Plug Gauge (NoGo) - Metric Fine - Right Hand - 6H - M120 x 4 is a precision inspection tool designed to verify internal, metric-fine threads in holes. Ideal for engineers, machinists, quality control professionals, and workshop technicians, it delivers quick, reliable checks to confirm holes meet exact size and tolerance requirements.
NoGo gauges are essential for rejecting out-of-tolerance components. This gauge helps you make clear, repeatable pass/fail decisions, reducing guesswork and rework in your manufacturing or maintenance workflows.
- NoGo gauge design for reliable QC: Captures out-of-tolerance holes quickly, supporting consistent pass/fail results and lowering the risk of undersized or oversize threads slipping through.
- Metric Fine thread compatibility: Specifically engineered for metric fine threads, enabling accurate verification of internal threads at M120 x 4 with minimal setup.
- Rugged, wear-resistant construction: Hardened steel construction with a durable knurled grip stands up to daily use in busy shops, maintaining accuracy over time.
Used in quality control, maintenance, and production environments, this gauge helps you speed up inspections, improve part fit, and enhance overall accuracy. With reliable performance and long-lasting durability, it supports consistent results across projects and reduces downtime associated with threading errors.
