high-quality: considering that this drywall screw is absolutely self-threading, it’s perfect for metal studs. Double threads within the high-quality drywall screws make self-setting up much more simple and easier.
They're driven using flat head screwdrivers or drills with flat head bits. They are really typical for jobs that use hand-pushed applications or have to have minimal torque.
you can find non-typical screws are around, but they’re generally labeled for a particular use (including “eyeglass screws”) as an alternative to discovered by measurement. the next are amid the commonest typical screw sizes:
