Applications

oCoarse Thread Drywall Screws ：Coarse-thread drywall screws work best for most applications involving drywall and wood studs. But the wide threads are good at gripping into the wood and pulling the drywall against the studs.
oFine Thread Drywall Screws：Fine-thread drywall screws are best for installing drywall to metal studs. But coarse threads have a tendency to chew through the metal, never gaining proper traction. Fine threads work well with metal because they are self-threading.
