されている。As shown in FIGS. 4 to 7, the screw 1) has a head 13 at one end of the body 12 and a tip 14 at the other end, and a thread 15 is formed from the tip 14 on the outer periphery of the body 12. , tip 14
A groove 16 is provided extending over the entire axial length of the body portion 12.
上記のネジ１）におけるネジ山１６は転造によりて形成
し、図示の場合このネジ山１５は胴部１２の途中までと
したが胴部１２の全長にわたって設けてもよい。The thread 16 of the above screw 1) is formed by rolling, and in the illustrated case, the thread 15 extends halfway through the body 12, but may be provided over the entire length of the body 12.
また、先端１４から胴部１２の全長にわたって設けた溝
１６は、第６図のような断面Ｖ字状やＵ字状とし、ねじ
込み方向の後方に位置する開口縁が切削縁１７となり、
この切削１ｉ１？が胴部１２の軸方向全長にわたってい
るため、ねじ込み中において、ねじ込んだ部分の全長が
切削効果を発揮することになり、ねじ込みが低トルクで
行なえる。Further, the groove 16 provided over the entire length of the body 12 from the tip 14 has a V-shaped or U-shaped cross section as shown in FIG. 6, and the opening edge located at the rear in the screwing direction becomes the cutting edge 17.
This cutting 1i1? Since this extends over the entire axial length of the body portion 12, the entire length of the screwed portion exerts a cutting effect during screwing, and screwing can be performed with low torque.
次に上記ネジ１）の製造方法を説明する。Next, a method for manufacturing the screw 1) will be explained.
ネジ１）の形成に用いる素線２１は、第１図に示すよう
に、複数の異種材料を組合せて同時に伸線することによ
り形成されている。As shown in FIG. 1, the wire 21 used for forming the screw 1) is formed by combining a plurality of different materials and drawing them simultaneously.
上記素線２１は、図示の場合、鉄やステンレスの如きネ
ジ材２２と、このネジ材２２よりも溶解温度の低いアル
ミ等の溝形成用材料２３との組合せからなり、ネジ材
２２は円軸の外周面軸方向にＶ字状の溝１６ａを形成し
た断面形状に伸線し、更に溝形成用材料２３をネジ材２

２２の溶解しない薬品で溶解°するような材料を用いる
ようにしてもよい。Note that the groove forming material 23 is not limited to a material that has a low melting temperature with respect to the screw material 22, and for example, a material that dissolves with a chemical that does not dissolve the screw material 22 may be used. .
前記素線２１を用いてネジｌｌａを製作するには、−船
釣な製ネジ工程を採用すればよく、素線２１の定寸切断
、頭部１３と先端１４の形成、先端１４から胴部１２に
対する転造でのネジ山１５の形成を行なう。In order to manufacture the screw lla using the strand 21, it is sufficient to adopt a boat fishing screw manufacturing process, which involves cutting the strand 21 to a fixed size, forming the head 13 and the tip 14, and cutting the strand 14 from the tip 14 to the body. A thread 15 is formed by rolling the thread 12.
製ネジ工程後のネジ１）ａは第３図に示すように、溝形
成用材料２３がネジ材２２の溝１６ａを埋めているため

６を備えたネジ１）が完成する。The screw 1) a in Fig. 3 manufactured by the screw manufacturing process is
Next, a groove forming process is performed and the groove forming material 23 is dissolved and removed, so that a groove 1 extending from the tip 14 to the entire axial length of the body 12 is formed by the dissolution and removal trace, as shown in FIG.
The screw 1) with 6 is completed.
上記溝形成工程は、加熱もしくは薬品への浸漬によって
行なうものであり、加熱や薬品による溶解は多数本を同
時に処理することができるという利点がある。The above-mentioned groove forming step is performed by heating or immersion in a chemical, and the heating or chemical dissolution has the advantage that a large number of tubes can be treated at the same time.
以上のように、この発明によると、先端から胴部の軸方
向全長にわたって溝を設けたので、ねじ込み使用時に胴
部全長が被ねじ込み部材の切削機能を有することになり
、低トルクでねじ込むことができる。As described above, according to the present invention, since the groove is provided over the entire axial length of the body from the tip, the entire length of the body has the function of cutting the member to be screwed during screwing, and screwing can be performed with low torque. can.
また、溝の形成を材料の溶解によって行なうようにした
ので、溝の形成処理が多数本同時に可能となり、大量生
産によるコスト低減を図ることができる。Furthermore, since the grooves are formed by melting the material, it is possible to form a large number of grooves at the same time, making it possible to reduce costs through mass production.
