I am continually suprised at how often I see people who should know better recomend the use of drywall screws for building construction, and a variety of carpentry and cabinet work, other than the hanging of drywal. I have seen it in both Fine Homebuilding and Fine Woodworking as well as other magazines and TV shows (along with the use of flat head screwdivers. So what to use for round head screws or pan head screws?).
There are a host of reasons for not using drywall screws in lieu of wood screws for attaching wood to wood or hardware to wood, but I will touch on only a few and suggest that editors start to address this issue and that practitioners of our wonderful trade and craft do some resurch on their own
Probably the most important reason is that drywall screws are not very strong, They are hard and sharp and easy to drive but they have very thin shanks and britle making the heads easy to break especially when driven with an inpact driver. Secondly, the threads go all the way to the head making them difficult or impossible to draw two pieces of wood tight . Other charicteristics such as bugle heads, lack of corossion resistance, very sharp points and ease of spliting wood make them unacceptable for much other that drywall.
