    Self-Tapping Screw VS Self-Drilling Screw

    Anyone know what is the difference between a self-tapping screw and a self-drilling screw?

    Self-tapping is most screws that have a pointy tip where self-drilling actually have a drill end at the start of the screw then transition into a regular screw.
    Tell me and I forget. Teach me and I remember. Involve me and I learn.
