Hex head self tapping screw

Metal ROOFING SCREWS. Our metal roofing screws are galvanized for corrosion resistance.  Hex washer head roof screw with rubber washer seal, seals roofing panel to screws to prevent leaks. The screw is Not Painted and is naturally a white blue color due to the galvanizing process on the screw.  If the hex head self-drilling screws are used in extremely hard materials, it is advised to use it after a pilot hole has been drilled. Our screws are case hardened and heat-treated for applications requiring fastening of soft materials on hard ones. With a lower installation torque, the threads on these screws allow for a quick transition from drilling to tapping. For effective penetration, make sure that at least three threads of the fastener are inside the material.  Self Drilling Screw SELF Tapping Screw Chipboard Screw Self Tek Screw Drywall Screw Hex roofing Screw Self Drilling Screw SELF Tapping Screw Chipboard Screw Self Tek Screw Drywall Screw Hex Roofing Screw
