Hexagon Wafer / Flange Head Self Tapping Screw High/Low Thread , Mechanical Galvanised ,Roofing Tek Screw
A self-tapping machine screw, differs in that the lower portion of the shank is designed to carve threads as the screw is driven into an untapped hole. This feature gives the self-tapping screw the advantage over a self-drilling screw as new threads are not cut should the screw be re-installed. Self-tapping screws are available in many different drive styles, head styles, and types, each offering its own benefits.
