[0002] Screws are a commonly used connector in all walks of life. Among them, self-tapping screws (i.e. screws with self-tapping external threads) are favored by many manufacturers due to their convenient and quick installation. The commonly used self-tapping screws mainly include three parts: nut, screw rod and tail tip.
[0003] When screws are used to fix objects to wooden materials, plastic materials and other fixtures in the field of mechanical engineering, the debris of the plastic, wooden boards and other fixtures squeezes the debris, and the debris cannot be discharged in time, which affects the penetration speed of the screws. As a result, the torque required for tightening is greater, which in turn reduces the penetration speed and leads to lower practicality. Utility Model Content
