What should be paid attention to for stainless steel raised countersunk head screws?

When customizing stainless steel raised countersunk head screws, many people will ignore one place, which makes the screws that are produced cannot be used by themselves. So what should be paid attention to when ordering this type of screw?

The head of the raised countersunk head screw is added with an arc on the basis of the original countersunk head. Many people will subconsciously include the size of this part in the length when calculating the length of the stainless steel raised countersunk head screws. In fact, this is wrong. Regardless of whether it is a countersunk head screw or a raised countersunk head screw, when calculating the length, only the countersunk head is calculated, and the length of the raised countersunk head does not include the raised part.

If the size of this part is included in the length when producing or making drawings of stainless steel raised countersunk head screws, the length of the produced screw will be shorter than the actual required length. If the screw is used in conjunction with the nut, it can be tightened. , This screw cannot be used. Or the screw is not used in conjunction with the nut, but only used to fasten two objects. At that time, the screw may be too short to be tightened.
