ZHONG JIU can provide almost any type of drywall screws you need for your project. The head of a drywall screw is shaped like the bell-shaped end of a trumpet. That's why it's called a buglehead. This shape helps the screws stay in place. It helps not to tear the outer layer of paper of the dry wall pegs. With bugle heads, dry wall spikes can be easily embedded into dry wall spikes. This creates a recessed surface that can be filled with filler and then painted to smooth the surface.
