Precision Dưỡng kiểm ren trong (Tol. 6H) - M 36 x 3.0

Checking a thread with the gauge is a simple process that determines the quality of your work:

• 1. Check the GO side (without the red ring): This side must screw into the cut thread of a workpiece by hand (without special effort). If this is not possible, the thread does not meet the desired specifications (=scrap).
• 2. Check the NO GO side (with the red ring): This side must not screw into the cut thread by hand (without special effort) for more than two turns. If it screws in further, the thread does not meet the desired specifications (=scrap).

For both the gauge and the workpiece, a reference temperature of 20° Celsius applies. Temperature differences can affect the measurement results, which is why a stable ambient temperature is crucial.

As a manufacturer, VÖLKEL can provide you with a factory calibration certificate upon request (price available upon inquiry). The calibration is carried out in a measurement lab independent of VÖLKEL's production, according to the specifications and standards (DIN, ISO, ANSI) set for the respective test item. The calibration is performed on IAC thread scanners.

Q: What exactly is a GO and NO GO gauge?

A: A GO gauge checks that a thread is not too small and meets the minimum size. It must screw in easily. A NO GO gauge checks that the thread is not too large. It should not screw in for more than two turns.

Q: Why is the NO GO side marked in red?

A: The red ring is a standardized and internationally common marking. It serves to clearly distinguish between the GO and NO GO sides of the gauge, to avoid mix-ups and increase safety during quality control.

Q: What does the 6H tolerance mean?

A: The tolerance class 6H is the standard tolerance for metric ren trong. It defines the maximum and minimum deviations from the ideal size and ensures that the thread has a good fit with most standardized screws.

Q: Why is the 20°C reference temperature important?

A: Metals expand with heat and contract with cold. The temperature of 20°C is the international standard for measurements. A deviation can falsify the measurement result, which is why you should bring the workpiece and the gauge to this temperature before checking.

Q: What is a factory calibration certificate?

A: A factory calibration certificate is a document that confirms the measuring accuracy of your thread gauge. It is issued by an independent measurement lab and proves that the gauge complies with legal and normative requirements. This is often essential for companies as part of their quality assurance.
