A thread limit plug gauge is a combination of a go plug gauge and a no-go plug gauge. The no-go end is marked with a red ring for easy identification. This 7-chiếc set in a sturdy plastic case provides you with all common metric sizes from M3 to M12 to ensure the quality of your finished threads according to DIN 13 standards.
Checking with the go end:
The go end of the Dưỡng kiểm ren trong must screw into the thread cut into a part by hand (without using excessive force). If you are unable to do so, the thread does not meet the requested standards (=scrap).
Checking with the no-go end:
The no-go end of the Dưỡng kiểm ren trong must not be able to be manually turned more than two turns into the cut thread (without using excessive force). If it can be screwed in further, 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 Dưỡng kiểm ren trong?
A: A Dưỡng kiểm ren trong is a measuring tool consisting of two parts: a go plug gauge and a no-go plug gauge. It is used for a quick inspection to determine if a finished ren trong is within the specified tolerances.
Q: Why does it have a go and a no-go end?
A: The go end (the minimum tolerance gauge) checks if the thread is not too small. The no-go end (the maximum tolerance gauge) checks if the thread is not too large. The thread only meets specifications if both checks are successful.
Q: Why is the no-go end marked in red?
A: The red marking serves for quick visual differentiation. It helps to avoid confusion and to immediately recognize the no-go end, as its application differs from the go end.
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: What are the consequences if a thread is scrap?
A: A scrap thread is not suitable for its intended use. It could cause the screw to not fit properly, come loose prematurely, or make the connection unstable. Such parts must be reworked or discarded.
