Self Drilling Screws
Similar to sheet metal screws, but we have a drill-shaped point to cut through sheet metal or steel which eliminates the need for drilling a pilot hole. These self-drilling screws are designed for use in soft steel or other metals.Self-drilling screw points are numbered from 1 through 5, the larger the number, the thicker metal it can go through without a pilot hole. A 5 point can drill a 0.5 in (13 mm) of steel, for example.
Self-Drilling Screws are also commonly called:
• Tek Screws
• Pro Points
• Self Tapping Screws
• Drill Bit Tip Screws
