Why are they called self-tapping screws?
Self-tapping screw is designated as such because it contains form mating threads in a pre-drilled hole into which they are driven.
How do you use a NEWSCREW’s self-tapping screw?
Position the screw straight in line with the hole and turn it in, one or two turns, by hand. This allows the screw to be left in the hole as you pick up your screwdriver or drill machine. Using firm short movements, screw the self-tapping screw in place using a Phillips or flat head screwdriver or drill bit
