If the framing is wood, you use the #6 x 1-1/8 drywall screw. If the framing is metal, you can still use those screws, but I find it goes faster if I use #4 x 1 inch drill tippedscrews. About 50% more to buy (at Drywall warehouses) but they save lots of time.
Half-inch drywall needs a 1-5/8" screw
ANS 2 - That is NOT correct, all the drywall pros I know use 1-1/8 on 1/2 board and 1-5/8 only on 5/8 sheets
Drywall screw guns are designed specifically for drywall applications whereas cordless drills are multipurpose. The screw gun will disengage from the screw when it reaches the proper depth for the screw,a cordless drill relies on the operator to know the proper depth.
Just exactly the same way you screw into wood.
A drywall dimpler is a drill bit used to countersink a drywall screw to the proper depth without breaking the drywall paper.
the drywall screw didnt come loose the paper that the screw is holding to the wall is what came loose. a screws function is mostly in the head or flange of it. if the head goes throught the paper rather than just indenting the paper, then it ceases to hold anything and the drywall will go in and out around the screw heance the term " screw pop" .
No, you don't use drywall anchors if you can use a stud.
Metal drywall screws are usually fit with a small plastic pre-grooved sheath which taps the screw into the drywall and wooden beam behind it. This results in a clean and secure penetration of the wood for each screw.
No, they are adequate for many uses.
A drywall screw gun can be purchased at many hardware stores such as Home Depot, ACE, or Lowes. They can also be purchased online in places such as Amazon.
They are poured in a continuous line in a drywall plant and cut to size after heating .
Actually it is better to use picture hanging hooks. They are specifically designed to hold the weight of the picture. You buy the hook size according to that weight. They are especially effective for use on drywall surfaces where there may not be any studs. Any screw you put in drywall (unless you hit a stud) will easily pull out because there is not a solid surface for the screw to grip and hold. I've seen pictures suddenly drop off a wall, breaking the glass in the frame because the picture was hung with an ordinary nail or screw.
Avoid seams above doorways because the slamming of the door can cause this area to crack
There are the drywall screw anchors that just look like a giant screw, they just screw in with a Philips and then the correct size screw fits into the same place as the screw driver. Blue (and other colours) plastic anchors you punch a hole in the drywall then push in the plastic insert until the little flange touches, then the screw goes into the center hole to expand for grip in the wall (these are good for low strength hold in other materials) Finally there are toggle bolts, they go through a pre drilled hole and the little wings pop out and the screw gets tightened until the wings clamp down from the far side of the drywall. All use a screw to either hold things up or clamp a hook or similar to the wall.
