Is it okay to use fine thread drywall screws when securing drywall to wood studs? What’s the worst that could happen if not?

    "Fine thread" DW screws are intended for fastening drywall to sheet metal studs rather than wood ones. In general they should work for wood studs but there is a modest danger of the screws stripping out the holes and coming loose.

  • The important point is not to use any variety of drywall screws for anything but drywall, or possibly as a temporary fastener. They are designed to take a specific static load, and are not reliable under higher or dynamic loads.

It's fine. They are primarily intended for metal studs but they will work fine in wood. Think about the force required to physically pull out one screw - even a fine threaded screw. Now given the fact that each sheet of drywall will typically have about 32 screws, the drywall itself will fail long before the screw is pulled out. To make yourself feel better, drive a fine threaded screw 3/4 of its length into a stud. Then grab pliers and try to pull it out...

Should be fine, though each screw will take longer to drive than with a coarser thread.

Don't use fine thread. Use the coarse thread screws. Over time wood expands and contracts with heat and humidity. Combine that with the weight of the drywall they WILL pop eventually. The question is will you still be there to fix all the popped screws? There are different threads for a reason if your going to spend the time doing something do it right the first time.

  • I mean they used to use nails tho Commented Dec 2, 2022 at 22:45
  • True there are a lot of things we "used to do" but found better ways. I remodeled many an old house and have seen those nails (popped out). Commented Dec 3, 2022 at 23:37

    Nah. I've demolished enough framing to know that fine-thread screws hold just fine. Screw pops occur due to missing the framing and gaps behind the drywall, not because of thread type.

IMHO, you'll have a problem if you use coarse thread screws in metal studs, but you shouldn't have one if you use fine thread screws into wood studs. Even if its thread is thinner, the screw is held in the wood on a longer part of it, and will require some effort to be extracted. The fine thread is necessary on metal studs because the contact between the screw and the stud is limited to the thickness of the metal, that is 1/16 to 1/32 of an inch, and a finer thread will provide a better grip. If it is solid with so little a contact surface, even in (lightweight) metal, it should be with a 3/4 inch length of contact in wood, even it it is not as much as with coarse thread ones. But it will not be weak. The fact coarse ones are better or recommended does not mean fine thread are bad. Try to divide the weight of a drywall sheet by the number of screws you will use, and you'll see the effort per screw is far less than the effort you would need to extract just one such screw with a lever. Also, think that, in the past, drywall was just nailed. How many falls of drywall sheets have your heard of?
