    1.Product Description

     

    Self-Drilling Screws are also commonly called: Tek Screws, Roofing Screws, Pro PointsSelf Tapping Screw, Drill Bit Tip Screws. Self-Tapping screws can cut their own threads as the screw is driven in to the material. They function by having a cutting edge which drills away the material, making a tiny hole for the screw to go into. This has nothing to do with the point of the screw but has everything to do with the threads which are designed to cut through the material. Similar to sheet metal screws, but they have a drill-shaped point to cut through sheet metal or steel which eliminates the need for drilling a pilot hole. These tek screws are designed for use in soft steel or other metals. Hex flange head self tapping screws generally made of C1022 carbon steel hardend or stainless steel SS410. It has an excellent drilling performance on hard material and sheet metals. C1022 steel self drilling screws could drill 1.5mm thick sheet metal while SS410 could drill even 5mm thick sheet metal. Hex flange head screws normally with a socke hex drive and also slotted drive options. There is some times an additional philips drive on the hex head. Please see below the guide dimensions for standard offers.
