What do you need to pay attention to when customizing raised countersunk self tapping screws?

When many customers customize raised countersunk self tapping screws, they basically fail to pay attention to some places, which results in that the screws produced by the screw manufacturer are not the same size as they actually require. So what should we pay attention to when customizing raised countersunk self tapping screws?

The dimensions of raised countersunk self tapping screws are generally composed of the following dimensions: head diameter, thread diameter, full length (excluding the raised head), groove shape, a thread pitch of self-tapping, and the angle of the countersunk head.

The full length of the raised countersunk self tapping screws is of particular concern. Many people count the convex part of the head as part of the full length. When you measure the size, you will find that the tolerance is out of tolerance. It doesn’t actually count as a bump on the head, so you don’t oversize it when you measure it.
