Why choose half tooth screws?
Half tooth screws are usually designed with threads at the tail, but there are no threads near the head. When the screw enters the preset hole, the chips scraped by the threads at the tail can be better discharged and more labor-saving.
Closer fit with preset holes, high locking stability
