COUNTERSUNK HEAD SELF DRILLING SCREW

Self drilling metal screws is a new type of high-efficiency riveting fastener. The tail of the self drilling metal screws has a self-drilling head in the shape ofa pointed tail. When using the self drilling metal screws to rivet the connected parts, no auxiliary processing is required on the surface and interior of the connected parts. The countersunk self drilling screws 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 countersunk self drilling screws is extremely high; it saves construction time to the maximum extent, improves construction efficiency, and improves construction efficiency. Economic benefits.

The connected parts riveted by countersunk self drilling screws have strong bonding force, high pre-tightening force and high stability of the connected parts. When selecting self drilling metal 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.
