Drywall Screw
The High-Low Drywall Screw requires less torque to drive than a standard Twin fast Drywall Screw, and is typically used to fasten drywall to lighter-weight metal or wood applications.
If working with heavier weight drywall, or if you are attaching the Drywall Screw to metal studs, a larger-diameter screw might need to be used. The primary use for drywall screws is securing whole sheets of drywall — typically 4 feet by 8 feet for DIYers — or partial sheets of drywall to wood or metal studs. Coarse-thread screws are generally used to secure the drywall to wooden frames, whereas fine-thread screws, also known as self-thread screws, are used for securing drywall to metal frames.
Drywall-to-wood screws feature coarse-threads, as opposed to lighter-gauge steel screws which have finer threads. The Phillips drywall screws with fine threads are self-threading, meaning that the finer threads surrounding the screws are capable of effectively cutting their own safe paths through material (in this case, a metal or steel stud). Based on my own experience working with screw joints, a limitation of wood screws is that often times the heads will dig into the wood.
They are less prone to breaking down than those from Drywall Screw, and when they break, they will usually have the head of the screw, or part of the screw, left behind on the piece of wood, without any metal sticking out of it from either side. While drywall nails are still in existence, and indeed they do have their uses, such as a fast method for fastening sheetrock, drywall screws evolved to become the standard way to fasten sheetrock to the studs, specifically due to the problem with popping nails. In construction, sheetrock screws have a number of alternative uses, because they are relatively cheap, feature a flat head that is less likely to get pulled through wood, and are thinner, making these self-tapping drywall screws less apt to crack the wood.
It is important to choose the correct types of screws in order to minimize your risk of damaging your sheetrock materials. Do not use longer screws unless you are screwing soft materials such as foam insulation to a base frame. This makes the head of your screw easier to push below the surface, but also exerts less force when you are tightening.
Tacks eliminate the trouble of carrying the screw gun while holding up the heavy sheetrock. Use a screwdriver to turn in the under-driven screws a few turns, or pull them out and use a screw gun to drive in the new screws along. With conventional tools, you may drive screws too far, opening holes in drywalls gypsum material and weakening joints.
Self-drilling screws means that the point of a screws point drills through the drywalls papery outer layers approximately three-quarters of the way through, and into a wooden stud, with no need for drywall anchors or a pilot hole.

Fine-thread sheetrock screw, or S-type screws, are used on metal studs, in contrast to coarse-thread ones, as coarser threads are less effective at drilling through metal, often gnawing through it, leading to a weaker holding power.
