Product Introduction

 

Bugle head: The head of a drywall screw is shaped like the bell end of a bugle. This is why it is called a bugle head. This shape helps the screw stay in place. It helps not to tear the outer paper layer of the drywall. With the bugle head, the drywall screw can easily embed itself into the drywall. This results in a recessed finish that can be filled with a filling substance then painted over to give a smooth finish

Sharp point: There are drywall screws that have sharp points. With a sharp point, it would be easier to stab the screw onto the drywall paper and get it started.

Drill-driver: For most drywall screws, use a #2 Phillips head drill-driver bit. While many construction screws have begun to adopt Torx, square, or heads other than Phillips, most drywall screws still use the Phillips head.

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. Additionally, they are easier to draw in because the shanks are slippery.
