Currently, the more common drill screws on the market include hex head self drilling screw and countersunk head drill screws. They are the more commonly used self drilling screws. It is a product with a drill bit tail, and its tip is the same as a twist drill bit. Different drill tail screws have different specifications.
The specification of hex head self drilling screw is that the length is about 20~125mm, and its diameter is 4.8 or 5.5mm. Others have a length of about 25~300mm and a diameter of 6.3mm.
The tail of the roofing screw has a self-drilling head in the shape of a drill tail. When using the self drilling roofing screws to rivet the connected parts, no auxiliary processing is required on the surface and interior of the connected parts. The drill tail screw can be directly used in setting materials and basic materials. Drilling, tapping, and locking can be completed quickly at one time. It can be quickly automatically drilled and directly tightened and fixed; the construction efficiency of self drilling roofing screws are extremely high; it saves construction time to the maximum extent, improves construction efficiency, and improves construction efficiency. Economic benefits. The connected parts riveted by hex head self drilling screw have strong bonding force, high pre-tightening force and high stability of the connected parts. When selecting self drilling roofing screw, you should choose the appropriate type, material and size of roofing screw according to the different materials and thicknesses of the connections to be fixed.
Hexagonal self drilling roofing screws can quickly and automatically drill holes and be directly tightened and fixed; the construction efficiency of Hexagonal self drilling roofing screws is extremely high; construction time is saved to the maximum extent, engineering construction efficiency is improved, and economic benefits are improved. The connected parts riveted by drill tail screws have strong bonding force, high pre-tightening force and high stability of the connected parts. When selecting drill tail screws, you should choose the appropriate type, material and size of drill tail screws according to the different materials and thicknesses of the connections to be fixed.
