This Philips Flat Head Self Drilling Screw is made from carbon steel and finished with a zinc coating for enhanced corrosion resistance. Designed for quick and secure metal-to-metal connections without pre-drilling this screw provides excellent grip and a flush surface finish, making it ideal for applications that require a neat, flat appearance. 

Designed with a cross-recessed head, they require a PH2 screwdriver bit for proper installation.
