Partial thread screw is one of the non-standard screws, the general tail thread and no thread near the head. When the screw enters the preset hole, the chip scraped out by the tail thread can be discharged better, and less effort. Moreover, the rod diameter strength of partial thread screw is greater than the whole thread screw, and the yield strength is also higher.
