Abstract
【解決手段】 ねじ回転工具係合部2を備えた頭部3と、頭部3と一体に形成し外周面が非円形をなすねじ山7を備えた脚部4とからなる非円形ねじ1において、非円形ねじの外周面の最大径をなす突出部8の先端より、ねじ込み回転方向Aに対して遅れ側の外周面に窪み10を形成する。また、非円形ねじの戻り側フランク面16のフランク角を5度程度に設定し、ねじ山角度を35度程度に設定する。それにより、窪み10によって雌ねじ形成屑を発生することがなく、またこの窪みにワークの素材が容易に流動し、盛り上がり部を窪み内に形成することができ、その部分で確実な戻り止め作用を行うことができる。また、この非円形ねじを容易にねじ込むことができる。
