SELF DRILLING SCREWS CSK HEAD 3/4″X 8

SELF DRILLING SCREWS CSK HEAD 3/4″X 8-These screws work as both a drill bit and a fastener. Self-drilling screws do not need a pilot hole because of the drill bit end. They work quite well at fastening thin pieces of metal together and were designed for exactly this reason. Customers use these when doing frame work on their cars, or attaching sheet metal to a metal frame. Why drill a bunch of holes into a metal sheet wearing out a drill bit, when you can use these guys. They also have much variance in types and uses than tapping screws
