What information does the torx screw iso standard need to provide?

Many customers will give the screw manufacturer a standard number if they need the torx screw iso standard. But can you give the standard number? In addition to the standard number, what information do I need to provide?

After the standard number is provided in the torx screw iso standard, the screw material, surface treatment, specific screw thread diameter and screw length are generally required. The provision of such information is relatively common.

But when the customer asks for a long screw length, such as M4*520. In addition to providing the information mentioned above, it is also necessary to provide the length of the thread and the diameter of the stem.

When the customer requests the inner plum with the column, the other dimensions follow the torx screw iso standard. Some customers have the size requirements for the inner column of the inner strip with the plum blossoms. Therefore, we also need to ask the customer whether there is a requirement for the size of the column in the middle, and if so, what the size of the column is.

When it is a step screw, the customer says that the size of the head is in accordance with the ISO standard number he provided, then we need to ask the customer the diameter of the step and the length of the step.

The information required for different screw types is also different.
