Tek screws, also called self-drilling screws, self drilling tek screws are self-tapping fasteners that have a drill bit end allowing them to be used for screwing materials such as wood and metal together without pre-drilling. Tek screws are best fitted with a high-speed impact drive. So Tek is to self-drilling screws as Kleenex is to nose tissue – a brand name. As the first of its kind, “tek” became synonymous with the self-drilling screw design, and now tek screws are essential for a range of applications today.
Each Tek screw features a carving piece on its tip, which is what makes self-drilling possible. This means you don’t need to create a pilot hole before the fastener, and it also means your work moves forward efficiently. Plus, Tek screws are versatile. Self-drilling screws have drill bit tips which are numbered from #1 up to #5, indicating the length of the flute. The flute is the part of the Tek screw that determines the metal thickness the screw can drill into. That means the bigger the number, the thicker the metal it can go through without a pilot hole, TEK 5 screws are used for fastening into structural steel. As a general rule of thumb, the higher the TEK number (the longer the drill point), the thicker the metal. It is fundamental that the point is high enough on the TEK scale to pierce the metal being drilled into.
Hex Washer Head self drilling screw is a kind of tek screw, which Depending on the thread drive pitch and hex washer head screw dimension, can be used for metal-to-metal fastening, metal and light steel framing, sheet metal and medium steel fastening, heavier gauge metal fastening applications, and solar panel installation.
