Wood to metal screws are made from C1022 steel, case hardened for fastening wood to steel or aluminum. #10-24 screw is a Phillips wafer head. #12-24 (#14 Head) and #14-20 screws are flat star head. The flat star drive head reduces end and cam load, handles greater torque than Phillips or a square drive, and eliminates turning and fastening damage. For the star drive use a T30 drill bit (not included). The scanner wings drill through wood and break off when they meet metal. The #3 drill point penetrates up to 1/4" of metal without pre-drilling. The shank slot holds steel chips and improves drilling action. Great for trailer beds and walls. All screws are 1000 hour salt spray tested with dacro coating. All Acorn International screws are packaged in 250 pieces.
