The invention discloses a screw with cutting convex teeth. The screw comprises a screw rod and a screw head integrally formed at the rear end of the screw rod. The screw rod comprises a screw rod body, a drill tail and a cutting portion. The drill tail is arranged at the front end of the screw rod body. The cutting portion and threads are sequentially arranged on the portion, behind the drill tail, of the screw rod body. The cutting portion consists of the multiple cutting convex teeth. All the cutting convex teeth are sequentially cut from front to back, and finally a threaded groove matchedwith the threads is formed in a cut object. Compared with the prior art, the screw with the cutting convex teeth has the advantages that the screw-in resistance can be reduced, damage to the threads and an anti-corrosion layer on the surfaces of the threads is reduced, and the surface of a fixed object is not prone to being damaged.
本发明公开了一种具有切削凸牙的螺丝，包括螺杆和一体成型在螺杆的后端上的螺头，所述螺杆包括螺杆体、钻尾和切削部，所述螺杆体的前端设有钻尾，所述钻尾后方的螺杆体上依次设有切削部和螺纹，所述切削部由若干切削凸牙构成，所有的切削凸牙按照由前到后的顺序依次切削最终在被切削体上形成与螺纹相配合的螺纹槽，与现有技术相比，能够降低旋入阻力，减少螺纹和螺纹表面防腐层的损伤，并且不易损伤被固定物表面。
