Abstract: A screw comprises: a screw head; a first screw rod extending from the screw head; and a second screw rod extending from a lower end of the first screw rod; a third thread and a fourth screw alternatively circles around the second screw rod; an angle between an upper surface of the third thread and an adjacent lateral surface of the fourth thread being larger than 90 degrees; and an angle between an upper surface of the fourth thread and a lateral surface of the third thread being larger than 90 degrees. Or only one thread circles around the second screw rod; an angle between an upper surface of the thread and an adjacent lateral surface of the second screw rod being larger than 90 degrees. There may be only one thread circling on the first screw rod, or two threads alternatively circling around the first screw rod.

Abstract: A screw capable of cutting and compressing dregs in an object to be drilled comprises: a tapered head with a small lower end; at least one rib being formed on and winds around the tapered area of the head. Each rib is formed with an outer wall having a first slope with respect to an outer wall of a tapered surface of the head and an inner wall with a second slope with respect to an outer wall of the tapered surface. Connection of the inner wall and outer wall is formed as a sharp knife portion. Each rib winds around the tapered surface of the head with an angle being equal to or larger than 360 degrees. By using the structure above said, dregs in screwing are compressed into the object to tighten the screw to the object to be drilled and no dregs expose out.

Abstract: A screw includes a head, a rod extending from a lower end of the head and a tapered drilling portion extending from a lowest end of the rod; the rod having a normal thread with a predetermined length; the normal thread extending from a lower end of the head to the tapered drilling portion, but having a predetermined distance from a tip end of the tapered drilling portion; an umbrella thread extending from a lower end of the normal thread to the tip end of the tapered drilling portion; the umbrella thread being formed by an upper thread surface and a lower thread surface. A second angle between the upper thread surface of the normal thread and the lower thread surface of the normal thread becomes larger and larger from the end near the normal thread to an end near the tip end.

Abstract: A tapered countersink drill bit includes at least two screwing knifes and at least one two screwing trenches and a rod body; a length of an edge of the left lateral side of each screwing knife being shorten than that of an edge of the right lateral side thereof; each screwing knife including a front drilling head; a tapered portion formed at a backside of the front drilling head; a rear drilling head formed at a backside of the tapered portion; the screwing angle of each screwing knife being identical from the front drilling head to the rear drilling head; and a screwing angle of each screwing trench being identical from the front drilling head to the rear drilling head; a width between two adjacent knifes at a front end of the rear drilling head being longer than a width between two knifes at rear ends of two rear drilling head.

Abstract: A screw capable of cutting and compressing dregs in an object to be drilled has a tapered head with a larger upper end and a small lower end, and a tapered surface being formed between the larger upper end and the small lower end; and at least one rib winding around the tapered surface of the head. Each of the rib is formed by an outer wall and an inner wall the connection of the inner wall and outer wall is formed as a sharp knife portion which winds around the tapered surface of the tapered head; and the outer wall is inclined so that a lower distal side of the outer wall is more near a center axis of the tapered head; and the inner wall is inclined so that an upper distal end of the inner wall is more near a center axis of the tapered head.
