What is a half thread screw?

When it comes to screw threads, probably a lot of people know self-tapping thread and machine screw. But for the half thread screw may not know much, it is what

half thread screw is generally refers to the screw head below the length of the rod is not basically the same as the length of the rod, is generally the length of the thread is less than the length of the rod, this screw is commonly referred to as half thread screw.

And half thread screw is what kind of screw, is it self tapping or machine thread? In fact, it is not explicitly fixed that the thread is self-tapping or machine thread. It is generally according to the needs of the customer to decide whether the thread is self-tapping or machine silk, and self-tapping and machine silk can be used in the half thread screws, so it is not clear what kind of thread this belongs to.

half thread screw with more generally is longer, or very long screw above. Because if these very long screws are made into full threads, then the cost will be a little more than that of a half-tooth screw. And if the thread is very long, the time needed to twist is also very increased, so some are not cost-effective.
