2 3 Point Square Drive Self Drilling Screws Metal To Metal # 8 X 1 - 1/4 ''

1. Descriptions:

 

    Pan head self-drilling screws feature a lower profile than oval or round screws, a flat or slightly rounded top and sharp vertical edges. Their unique design is suitable for high-torque installations into wood or metal. Use them for all general purpose applications including construction, HVAC and other installations, roofing and more.


     Pan Head Self Drilling Screws are designed for use in metal applications. Like self tapping screws,  self drilling screws cut threads while being installed. A self drilling screw, however, has a notched point that acts as a drill point and therefore does not require a pre-drilled hole before installing

 

      We are factory who is specialized in manufacturing many kinds of screws for more than 15 years, we can produce it according to many standard, such as DIN, JIS, GB and so on...every month we can ship 15-20 containers to the world market....

 3. Drilling Screw Design Features:

 

       When selecting a self-drilling screw, consider the material thicknesses and types of materials to be joined. Following are some key design features to look for when selecting suitable fasteners.

 

        Drill Flutes allow drilled material to exit the hole. Completely embedded flutes can no longer remove these chips, which contain approximately 80% of the heat created by the drilling process. A buildup of this material can cause the point to over-heat and fail.

 

         Point Length determines the material thickness which the screw can reliably penetrate. The unthreaded portion of the point, (pilot section) must be able to completely drill through the material before the threads engage. If the threads engage before drilling is complete, the fastener can bind and break.

 

         Point Wings are used on some screws that fasten thicker materials, such as wood, to metal. The wings enlarge the hole in the fastened material, allowing the threads to pass through without contacting the fastened material. This added clearance prevents separation of the fastened material from the base metal (known as "jacking"). The wings will break away on contact with the metal before the threads engage in the metal.
