The sq disk will take doing so connection separating app and screw and creates a contact point which not only supply much better grip during the drive, but attaches so snugly that you can do the job upside straight down or sideways without losing contact using the drive head. The regular fastener head has its uses, but for comfort the sq drive and Phillips head offer added control.
