This creation is about a screw structure with a cutting groove. It is a self-tapping screw used to fix the bone plate to the bone. It will penetrate the two layers of hard bone of the bone, and the front cone is provided with a cutting groove The cutting groove will not extend to the screw part of the screw and cut off the extra thread. Therefore, the contact area between the screw and the hard bone can be maintained, thereby ensuring the fixing ability of the screw.本創作係關於一種具切削槽之螺絲結構，係為用於將骨板固定於骨頭上之自攻螺絲，其會穿透骨頭的兩層硬質骨，而其前端錐部開設有切削槽，此切削槽不會延伸至螺絲的螺桿部而切削掉額外的螺牙，因此可維持螺絲與硬質骨的接觸面積，進而確保螺絲的固定能力。
