Can the thread of the pan pozi self tapping screw go through the stop gauge?

Previously, there was a customer from Ningbo, Zhejiang. They were making braille readers. They needed a precision small pan pozi self tapping screw, and they needed a go-no-go gauge 6G on the drawing.

Generally speaking, the function of the go-no-go gauge is to check whether the thread produced by the manufacturer complies with the industry standard and whether it is within the tolerance range required by the manufacturer. However, the go-no-go gauge is used to detect machine thread, not self-tapping threads.

Therefore, we tell customers that self-tapping threads do not require go-no-go gauges, and only machine threads require go-no-go gauge inspection. Later, the customer said that he made a mistake. This pan pozi self tapping screw does not need a go-no-go gauge, but another pan head machine screw needs a 6G go-no-go gauge. At the same time, the customer also said that the thread tolerance requirement of the self-tapping screw is ±0.05mm, can it be done?

We can complete the pan pozi self tapping screw tolerance that the customer said. After confirming the material, strength and tolerance, the customer quickly confirmed the order.
