GO Ring gauges, 7-piece set in sturdy plastic case M 3 - M 12 by VÖLKEL, item no. 16491, suitable for thread inspection and quality control.
A GO thread ring gauge is a precise measuring instrument for the quick and reliable inspection of external threads. This 7-piece set in a sturdy plastic case provides you with the most common metric sizes from M3 to M12 to ensure the quality of your manufactured parts. The ring gauge must be able to be screwed over the entire length of the thread to confirm dimensional accuracy.
Checking with the GO thread ring gauge:
The GO thread ring gauge must be possible to manually screw into the entire thread of the part (without using excessive force). If you are unable to do so, the thread does not meet the requested standards (=scrap).
Important note: The reference temperature for parts and gauges is 20° Celsius.
Q: What is a GO thread ring gauge?
A: A GO thread ring gauge is a test tool designed specifically for checking external threads (on bolts, screws, etc.) to ensure they are not too large and are within the specified tolerances.
Q: How does a GO ring gauge differ from a GO/NO-GO ring gauge?
A: A GO ring gauge by itself checks the maximum tolerance of the external thread. In contrast, a separate NO-GO ring gauge would check the minimum tolerance. A thread is considered "good" if it fits into the GO ring gauge over its entire length and either does not fit into the NO-GO ring gauge at all, or only fits into the first 1-2 threads.
Q: What types of threads is this set suitable for?
A: This set is designed for metric ISO threads according to DIN 13 from M3 to M12. It is a universal tool for quality control in many applications.
Q: What does the reference temperature of 20° Celsius mean?
A: The 20°C reference temperature is the standard at which all threads and gauges are calibrated and tested. Temperature differences can cause the material to expand or contract, which would distort the measurement result.
Q: How should I best store the ring gauges?
A: The ring gauges should be stored in their supplied plastic case in a dry, clean, and dust-free place. This protects them from corrosion and damage, ensuring their precision and longevity.
