Hex Washer High Head Serrated Self Drilling Screw Zinc

High Head Self-Drill Screws have a drill shaped point to eliminate the need for pre-drilling a pilot hole. The drill point cuts through sheet metal or steel, which along with other features creates an ideal product for HVAC projects as well as curtainwall and glazing applications. The High Head helps the screw stay in the nutsetter during installation which reduces worker fatique and waste. The serrations under the head keeps the screw from backing out due to vibration.
