Drywall Screws Introduction:
Drywall screw is always used for fastening sheets of drywall to wall studs or ceiling joists. Compared to regular screws, drywall screws have the deeper threads. This helps prevent the screws from being dislodged easily from the drywall. Drywall screws are made of steel. To drill them into the drywall, a power screwdriver is needed. Sometimes plastic anchors are used together with drywall screw. They help balance the weight of a hung object evenly over the surface.

Countersunk Head Self Tapping Screw Introduction
Countersunk Head Self Tapping Screw is used for all sorts of material including wood, metal, and brick. Self-tapping screws also called sheet metal screws, are very versatile. They can be used to securely fasten metals together. These screws cannot drill through metal and require a pilot hole to be pre-drilled before installation. A pilot hole is created by using a drill bit which is slightly smaller than the screw and the threads of the screw tap the metal or wood while the screw is being installed. A countersunk or as regularly shortened as CSK Screw is a fastener that is sunk into a piece of lumber. The heads of the Stainless-Steel Countersunk Screw will sit below the surface of the material.
