Abstract: A versatile screw includes a head, a shank, a thread unit, and a drill portion. The drill portion includes a drill body on which two opposite groove regions and a drill thread unit can be arranged. The drill body defines a drilling section. Each groove region includes at least one wall joined to the drilling section, an accommodation area enclosed by the wall, and a cutting rib portion protruding from the wall. The drill thread unit is spirally disposed on the drilling section and partially cut by the groove regions, thereby forming at least two drilling thread segments. The cutting rib portions cooperate with the drilling thread segments to assist the drilling section in reaming and generating downward pulling force, thereby executing an efficient drilling operation capable of attaining a stable initial-cutting effect, decreasing the drilling resistance and preventing the cracking problem of a workpiece.

Abstract: A method for manufacturing a multi-functional fastener includes a preparing operation, a forming operation and a threading operation. The preparing operation prepares a metal blank cut from a length of a metal material. The forming operation is executed so that the metal blank forms a shank, a head, and a drilling portion connected to the shank. The threading operation is executed to roll the metal blank with a thread rolling set having two opposite rolling plates. Each rolling plate has slit grooves and convex units arranged in alternation. Each of the convex units has protrusions each situated between two adjacent slit grooves, which allows the threading operation to equip the shank of the metal blank with thread convolutions, slots formed between the thread convolutions for helping quick removal of chips, and main ribs formed between any two adjacent slots for increasing cutting efficiency.

Abstract: A screw includes a threaded shank and a head with a first surface. Communicating sockets formed in the first surface include a Pozi-type socket and a drive socket. The drive socket includes rounded portions, arched portions alternating with the rounded portions, and a conical portion connected to the rounded portions and the arched portions to define a first reference line and a second reference line parallel to a central axis of the head. The rounded portions are inclined outwardly from the first reference line, and the arched portions are inclined outwardly from the second reference line. Thus, a first room enclosed by the rounded portions and the arched portions increases gradually towards the first surface. By a combination of the above sockets, the head cooperates with different driving tools for delivering driving force efficiently and is more convenient to use.

Abstract: A screw includes a shank with an outer periphery, a head connected to the shank, and thread convolutions spiraling around the shank in a right-hand direction. The outer periphery defines opposite first and second peripheral envelope surfaces. A cutting slot unit is formed on the shank and arranged on the first peripheral envelope surface. The cutting slot unit includes a first cutting slot with two first edges and a second cutting slot with two second edges. The first edge extends in an extension direction opposite to the right-hand direction. One first edge of the first cutting slot is parallel to one second edge of the second cutting slot. The opposite extension of the cutting slot unit assists the screw in screwing quickly, attains quick removal of chips, and increases the fastening effect by pressing chips downwards.

Abstract: A quick fastening screw includes a head, a shank with spirally-disposed thread convolutions, and a drilling portion. Each thread convolution has at least three flank sections and at least three arc sections each formed between any two adjacent flank sections. Two ends of each arc section and the flank sections adjacent to the arc section are respectively intersected to thereby form two joints. Between the two joints is formed a curved cutting portion which forms a radian not more than a quarter of a maximum thread radius so that each curved cutting portion becomes sharp to cut quickly, speed up a screwing operation, decrease the friction between the thread convolutions and a workpiece, and reduce the resistance and torque. The non-circular thread convolutions also receive cut debris efficiently and prevent the cracking of the workpiece caused by the undue accumulation of the debris.
