1-5/8" coarse thread drywall screws and 3/32" drill bit.

Predrill ftw or dont go so close to the edge. It has nothing to do with screw size or drill.

Yes it does. It has everything to do with screw size and drill... //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

The "standard" coarse 1.75" drywall screw is best. If you want to get cute, Lowe's sells a little set that allows you to countersink the screw so you can go over it with putty for a very clean look.

Me personally, when I use screws I use the wallboard screws as they self-countersink and have a slightly better grip. However they are 2.5x more expensive. Pre-drilling is not required...however, I still think it works best as the screw doesn't dance.

To counter sink, I use a drill bit = to the size of the head of the screw, and just screw in at a high RPM with low down force... it will just act as a counter sink. I've done this many times and it works out well each time. You just have to make sure it doesn't dig in.

Yea, 3/32" works everytime for me with the coarse-thread drywall screws (and I'd use the 1 5/8" as well)

And yea, you can do this...or tighten it down like a man into the MDF //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif jk...in the future i'll hopefully buy a countersink chuck...I want one //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Its a lot faster to get a countersink/drill bit combo. Speeds things up.
