Use coarse-thread drywall screws for most wood studs. Coarse-thread drywall screws work best for most applications involving drywall and wood studs. The wide threads are good at gripping into the wood and pulling the drywall against the studs.

Drywall screws are fully threaded screws for interior projects, such as securing drywall to studs. Coarse-threaded screws are for hanging drywall on wood studs, while fine-threaded screws work with metal studs.

Screws typically pop out of drywall for one of two reasons: they were installed too deep, or the studs have expanded and contracted. If you drive a screw too deep through the drywall and into the stud, it may pop out. Over time, the constant contraction and expansion of studs can cause screws to pop out.

Simple Answer: NO – A screw directly into drywall will not hold. You need to use some type of picture hanging hardware to hang a heavy picture securely. The threads of a screw into only drywall, without an anchor, will NOT permanently hold in the drywall.

Make sure the screws go securely into the framing. You want the new screws recessed slightly without breaking the drywall covering. These screws keep the drywall from moving, which prevents additional popped nails or screws in the future.

Nail pops, the condition where a nail either pops through the drywall surface or is pulled deeper into the drywall leaving a depression, are, like many drywall problems, often the result of rough framing-lumber shrinkage. Framing lumber used in new construction often shrinks after it is installed.

Apply 2-3 layers of drywall mud over the screw, depending on how long the screw head is. The holes will be fine – however if you’re concerned – just put some scrim tape over. Yes, it takes time for the compound to dry, but don’t try to rush the drywall taping process along by applying fewer, thicker coats.
