    Introduction of countersunk drill screws

    A countersunk drill screw is a special type of screw with a sunken head and a drill tail that allows it to be easily driven into the fixing with a screwdriver or self-tapping nails. This type of screw is characterized by its high connection strength, which is able to hold the connecting parts firmly together through the countersunk design of the head and the thread of the tail. At the same time, the threaded part of the countersunk drilling screw can be subjected to different degrees of heat treatment as needed to improve its tensile strength and shear strength.

    The tail design of the countersunk drill screw can be adjusted according to the shape and size of the part to be connected, so that it can be easily passed through the part and connected. In addition, during the connection process of the countersunk drilling screw, the countersunk design of the head can make the thread automatically locked, forming a self-locking structure, which effectively prevents the thread from loosening and ensures the reliability of the connection.

    Countersunk drill screws have a wide range of applications and can be used to fix wood, plastic, leather and other materials, in home decoration. It has a wide range of applications in the fields of machining, automobile manufacturing, and electronics manufacturing. With the advancement of material technology and manufacturing process, the future development of countersunk head drilling screws will be more diversified and environmentally friendly to meet the needs of more special application fields.

    Countersunk head drill tail screws are also known as countersunk head dovetail screws. Drilling screw is a new type of high-efficiency riveting fasteners; drilling screws are named drilling tail self-drilling self-tapping screws because of drilling tails, also known as self-drilling self-tapping screws, drilling tail screws, drilling tail wires, drilling tail nails, self-drilling screws, drilling tail self-tapping self-drilling screws, etc. The tail of the drilling screw has the self-drilling head that is in the shape of drilling tail or sharp tail, when riveting the connected piece with the drilling screw, the surface and the interior of the connected piece do not need auxiliary processing, the drilling screw can directly be drilled, tapped, locked on the setting material, the base material is completed quickly at one time, can be quickly and automatically drilled and directly screwed and fixed; the construction efficiency of the drilling screw is extremely high; the construction time is saved to the greatest extent, the engineering construction efficiency is improved, and the economic benefit is promoted. The connected parts riveted by the drill screws have strong bonding force, high preload, and high stability of the connected parts. When selecting the drill screw, it is necessary to choose the appropriate model, material and size of the drill screw according to the different materials and thicknesses of the connectors fixed according to the need.
