How much force can a drill tail tapping screw bear?

0.6 tons to 1. 1 ton. The self-tapping screws of the 4-point 8-level drill tail can bear 0.6 tons and 8-point 8-level tension, and each can bear 1 point 1 ton tension. When the self-tapping screw is used to stick the wallboard, it can be screwed into the wallboard to drill holes by itself. Through the construction of special electric tools, the drilling, tapping, fixing and locking of the self-tapping screw can be completed at one time.
