About Steel Self-Drilling Screw, Zinc Plated Finish, Flat
Flat head screws give you a flush surface when used with countersunk holes. The underside of the head is angled 82 Degrees. Length is measured from top of head. Self drilling screws, drill their own hole in thin sheet metal, heavier gauge metals and other materials, then form close mating threads in the hole. The Self drilling screw is ideal for automated assembly and reduces or eliminates the need for drill bits or taps. Once the hole is drilled, self drilling screws tap the hole in the same way as thread forming or thread cutting screws do in a pre-drilled hole. They are also designed to eliminate paint build-up, weld flash, or foreign material that may occur in pre-drilled or pre-punched holes. Unlike tapping screws, these screws drill a hole and tap a thread in a single operation. All you need to install them is a power driver. For effective fastening, the drilling point must fully penetrate all pieces of material being fastened before the first thread engages. Zinc-Plated Steel offers good corrosion resistance.
