Flat Head Screws --The flat head screw design offers a flat top surface with a counter sunk load bearing surface. Theflat head sits flush on the surface and offers a deep recess to minimize driver bit cam-out. They have our patented Lo Root® coarse thread design for superior holding power while reducing splitting or crumbling of the material. For added protection from wood splitting, we also offer them with a type 17 cutter point.
