The Asimeto Ring Thread Gauge (NoGo) for metric right-hand threads delivers precise pitch-diameter verification in a compact, easy-to-use tool. Designed for machinists, quality control professionals, and assembly technicians, it helps ensure fasteners meet exacting size standards every time.

• Series: 686 Series ring gauge crafted for high-precision measurement
• Designation: NoGo gauge to confirm maximum allowable thread size
• Thread size and type: Metric M4.5 x 0.35, right-hand thread
• Tolerance class: 6g, providing strict control over pitch diameter
• Measurement principle: Determines pass/fail by whether the fastener clears the NoGo gauge
• Material and build: Durable, precision-finished metal designed for repeated use
• 用途 and application: Ideal for inline QC, fastener inspection, and assembly validation in manufacturing settings
• Wear and longevity: Built to withstand regular use in busy workshop environments

Using the NoGo gauge, a fastener that passes through indicates its pitch diameter is within the maximum permissible limit; if it fails to pass, the thread is larger than allowed. This clear go/no-go feedback reduces misfits, minimizes rework, and promotes reliable, safe connections across production runs. The 686 Series’ emphasis on precision and durable construction makes it a dependable choice for maintaining tight dimensional control in metric threaded assemblies.
