Stainless Steel 316 304 M2 - M10 self drilling screws for thick steel
1. Product Description
Self-drilling screws, also CALLED TEK screws, do not require a hole to be drilled prior to use which cuts down on time needed to drill and fasten materials by combining them. These have the same heads as traditional bolts and screws, but the fastener is designed with a drill flute on the tip to drill/fasten at the same time. Useful for quick sheet metal fastening and other applications like metal to metal or wood to metal.
Self drilling screws have a drill bit point. Pan heads are slightly rounded with short vertical sides. Phillips drives are + shaped for a phillips screw driver.
Flat heads are countersunk (cone shaped under the head) with a flat top. Phillips drive is x-shaped for installation with a phillips screw driver.
he generic name for these screws are Self Drilling,he length of the drill point determines the material thickness which the screw can reliably penetrate.When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined.
The properties of drilling screw : 1) Exact forging standard of knife edge and high hardness of surface make it easy to drill. 2). The Special technology treatment of the surface makes the product anti-corrosion , antirust and durable. 3) Using the advanced technology to control the core hardness, avoiding rupture effectivity,

3. Application
Self-drilling screws have hardened drill points that will drill and thread in structural steel, mild steel, aluminum and wood. These drill points are manufactured in the same method as the high speed drill bits. Self-drilling screws are available in a variety of finishes with unique product features to suit a wide range of environmental conditions.
- For the fastening process in steel, they are used on steel frame construction or fastening other materials on steel.
- For the fastening process in wood, they are used for applications in wood structures or industrial lightweight constructions, such as roof deck, flooring.
- For the fastening process in aluminum, they are used for special industrial applications, construction and manufacturing of windows.
