抗によシねじ込作業が軽快に行われないことがあった。Conventionally, a ninth cutting blade for drilling holes is formed at the tip of the shank, and a K die is rolled around the shank to form a thread, and the round K leg is shaved with the cutting blade at the tip to create a nine-thick material. 9) Cutting waste thread wraps around the shank and cuts a thread that is thicker than the diameter of the thread ridge, resulting in irregular female threads of thick material.9) Cutting waste enters between the threads. Due to heavy wire resistance, screwing work could not be carried out smoothly.

。The present invention was invented in order to eliminate the above-mentioned drawbacks, and consists of the following parts: the head is press-formed with a header, the lower end of the shank is machined by round wire rolling processing, and the conical part is machined by rolling. A die is attached between the lower part of the head and the base of the conical part on a shank in which two or more slots are formed in the shaped part and a cutting edge is cut upward from the tip of the conical part between each slot. The screw is rolled by a rolling process to form a screw having nine raised peaks and valleys, and along with this four-ring process, a die is used to collect cutting waste between the screw and the base of the conical part. A cylindrical cutting waste reservoir with an outer diameter equal to or smaller than the root diameter of the screw is formed, and the cutting edge of the conical part is made by making a large hole in the thick material. The cutting waste is stored in a cylindrical cutting machine JiIII11 to prevent the cutting waste from creeping up to the threaded part, and the screw is used to form a female threaded pipe in a thick material. The object of the present invention is to provide a screw that securely fixes the screw.

要は別途行っていた圧造１徊を省略することができる。l is a shank made of iron lI material, 2 is this shank
3 is a square bulge for fitting a dryer formed in the center of the half-round part 2, and 4 is a nine-conical part formed in the lower end of the shank 1. In this conical part, slots 6.7.8 are formed at evenly spaced intervals from the tip 6 to the base of the conical part, and the tip 5 is formed between the slots 6, 7.7, 8.8, and 6. Cutting edges 12, 13, 14 are formed in the grooves 9, each having a biting edge 9, 10, 11. These slots and cutting edges are sharply formed with a cutter. A thread 16 is formed between the washer q of the shank 1 and the conical part 4 on one side d1 and d of the dies D1 and Dl. The diameter of the thread of the screw 16 is larger than the diameter of the shank 1, and the thread diameter of the screw 16 is smaller than the diameter of the shank 1. Below the lid surfaces d1 and d of the dies D- and Da, there is a sub-type having a ridge 17 and a trough 18 in the first half 19 which intersect with the direction of the lead of the screw 16 in a cross shape, and a nil protrusion 21 in the second half 20. Dies 22 and 23 are attached, and these sub-dies 22 and 23 are used to cut the shank 1 between the lower end of the screw 16 and the proximal end of the conical part 40, with a height of 1, and the screw 16. A cylindrical lid cutting waste reservoir 24 is formed having an outer diameter smaller than the outer diameter of the crest and the base of the cutting edge of the conical portion 4. The shank of the cylindrical cut sea bream 1$124 part has 2 secondary dies.
1! Since rolling formation is performed in steps 23 and 23, it is possible to omit the pressing step, which was previously performed separately.

。Due to the presence of the cylindrical cutting breast groove 24, the cutting waste of the thick material cut by the cutting blade of the conical part does not enter the thread lead of the screw 16 and the conical lid cutting shoulder 11m is removed. 12
4, it can improve the cutting performance of the cutting blade, and there are no holes that can destroy the internal threads created in thick materials.
