ProMaster™ Saw Tooth Screws - Finally, Screws that Actually CUT their Own Pilot Hole! Take a look at the most revolutionary thing to happen to screw threads in a very long time! You don’t need to look too closely to see that threads near the tip have saw toothed scallops in them. These scallops help the thread actually cut its way into the wood, and help prevent splitting. In fact, recent testing of various lengths driven into a maple block revealed no splitting, unlike both the standard point and Auger Point screws driven into the same block. Even better, manufacturer’s tests show that holding power is increased as well! Should you still drill a pilot hole? For fine cabinetry, I would. After all, the screw is still acting like a wedge to force the wood fibers apart. Drilling a pilot hole removes the excess material, so the screw’s sole function is clamping. #2 Combo Recess. Made in China under US patents.

Comments about 8 x 1-3/8 ProMaster Wood Screws, Unplated Steel, Flat Head, Combo Drive:
I have been using these screws for 5+ years as a professional cabinet and built in maker.. I have tried others types including the aussie screws but these work best. they crank the wood together, no need for pre drill unless hardwood and near the edge then I recommend pre drill. they recess nicely and hold well. highly recommend them
Bottom Line Yes, I would recommend this to a friend

About Me Avid Do-It-Yourselfer
Used these screws to fasten through 5/8 " plywood attic flooring into 7/8" soft pine subfloor/ second floor exposed ceiling. Nothing else I tried would quite work. These worked, but not by much.1.5 " is a little too long here, as the screw tips will show. It would have worked better if the 1.375 " were available in a #9 or even a #10 screw.
