Self-tapping countersink head

Premium 305 stainless steel screws from GRK are the ultimate for corrosion-free outdoor performance, which is why they come with a lifetime warranty against rust and staining. Each screw features an underhead with saw-blade like cutting teeth and six self-contained cutting pockets, which transport drill dust away from the edge of the screw hole while cutting a perfectly clean hole. The screw head closes the hole off with precision, leaving no damaged fibers around the head. Because of the angle on the underside, the screw also fits perfectly into the pre-countersunk holes of hardware fittings such as hinges or locks. Technical Details: High grade 305 stainless steel screws. No pre-drilling unless material requires it. Self countersinking heads. Starhead recess / non-stripping heads. Can be used with fibrous materials. Robust threads. Works well in wood, particle board, plastic, sheet metal, cement fiberboard, composite decking, wood decking, and melamine.

I'm an amature woodworker and I was turned onto these screws after I watched a video of a pro ww. These screws go in super easy and create a strong joint. I was concerned about the size of the screw for my application (building carcasses) but these go in easy and they don't split the wood (3/4 ply or hard wood). Of course they countersink themselves and leave a clean hole and with the torx head they don't strip.
So far these are my favorite screws. I've tried spax which are the closet to this screw but I didn't have the same success as I did with the R4's.
I will never buy another wood screw again. Simply the best ones every. The tech in these, you can drive these in without power tools.
These screws are perfect for securely mounting things to stud walls. High quality, self starting (no pilot hole needed). I will buy again when I run out.
