Someone asked sometime back about the recex screws offered at
I can't get these locally so this will be fine for me. I got them in
3 different lengths and I also bought some 3 1/2" washer head screws for cabinet mounting.I have never used a screw as aggressive as these and the nibs do indeed prevent the need for countersink drilling. I guess it is the prelube that makes them so smooth on the drive. If you have not tried them, you ought to.
