Wall Plug

Wall plugs can be applied to ceilings, floors, walls, and plasterboard. A large-headed screw that passes through holes made in any material or product, on iron or wooden parts, and is tightened by attaching a nut to its end, is called a bolt. It generally works with a nut. It is frequently used in the construction and machinery sectors.Self-Drilling Screw
Drill-tipped screws are also known as self-drilling screws. The hard part located at the tip of the screw performs the function of a drill, hence it is called a self-drilling screw. When using these screws, the head of the screw should be gripped with a screwdriver; the drilling process should be carried out by turning the tip at a certain speed. A self-drilling screw is a new generation screw type that, thanks to its hard and twisted tip, provides the convenience of penetrating wood without pre-drilling. Another name for a self-drilling screw is a drill-tipped screw.
