Drywall Screw: Entry-Level Drywall Screw Information

Drywall screw – Drywall screws have become the standard fastener for securing full or partial sheets of drywall to wall studs or ceiling joists. They are with bugle head, Philips head No.2 cross drive, fine or coarse thread, sharp or drill point. The most popular surface treatment is phosphate (black or gray color)



  • Bugle head: Bugle head refers to the cone-like shape of the screw head. This shape helps the screw stay in place, without tearing all the way through the outer paper layer. 


  • Thread, coarse thread drywall screw for most wood studs. Fine thread drywall screws are self treading, so they work well for metal studs.


  • Sharp point: Some drywall screws specify that they have a sharp point. The point makes it easier to stab the screw into the drywall paper and get the screw started.


  • Coatings: Black drywall screws have a phosphate coating to resist corrosion. A different type of drywall screw has a thin vinyl coating that makes them even more corrosion-resistant. Such as electric galvanized zinc coating. Additionally, they are easier to draw in because the shanks are slippery.


  • Sizes of drywall screw, the common diameter as #6/#7/#8/#10 (3.5mm,3.9mm,4.2mm,4.8mm); Lengths range from 3/4″ to 6″ (13mm~152mm),but only small sizes are available in short lengths and large sizes in long lengths. Short lengths are fully threaded and long lengths are partially threaded. Length is measured from the top of the head to the tip of the screw for both sharp and drill points.
