Description

The Asimeto Ring Thread Gauge (NoGo) is a precision tool designed for quality control of metric coarse 6g threads, specifically calibrated for right-hand M4 x 0.7 fasteners. Part of the 684 Series, it ensures the thread stays within tolerance and checks the minimum material condition to verify the part meets the lower size limit.

  • Series & Calibration: 684 Series ring gauge for metric coarse 6g threads, calibrated to ensure the thread remains within tolerance.
  • Thread Size & Hand: Right-hand M4 x 0.7 thread specification for consistent measurement results.
  • NoGo Function: Checks the minimum material condition, ensuring the threaded part is within the lower limit of the allowable size.
  • Design & Handling: Precision-machined body with a knurled outer edge for secure grip and repeatable measurements.
  • Ideal Use: Ideal for verifying threaded parts that should not be larger than the maximum allowable size, supporting reliable quality control in manufacturing and inspection workflows.

In practice, this gauge helps inspectors and machinists quickly determine whether a threaded component meets the required size limits, reducing guesswork and rework. By focusing on the lower limit of the size spec, it provides clear, actionable feedback during QC checks and helps ensure consistent thread integrity across production runs.
