About Pan Head Self Drilling Screws
Pan head self-drilling screws are designed with a flat top and a drill point at the tip to pre-drill the screw hole as you go with a “thrilling-like” action (threading or drilling) to eliminate separate drilling, tapping, and installation actions. The length of the drill determines the material thickness which the screw can reliably penetrate.
They are ideal use for wood, metal, or other tough materials and known for their efficiency application
performance, and endurance. You could see them around because they are widely used in a variety of industries
such as construction, manufacturing, engineering, assembling, and so on.
The quality carbon steel material screws with zinc coating or nickel-plated provide perfect strength and good corrosion resistance in bad
environments like high temperature, cold weather, and high humidity areas without the need for time
consuming and costly maintenance.
