Flat Head Self Drilling Screw features a flat top with a conical bearing surface that sits flush with the material when fully installed. This type of screw is designed to drill its own hole into materials such as metal, wood, or plastic without the need for pre-drilling, making it highly convenient and efficient for various applications. The self-drilling tip, which resembles a drill bit, allows the screw to penetrate surfaces easily, while the sharp threads ensure a secure hold. Commonly used in construction, automotive, and manufacturing industries, these screws are available in different lengths and diameters to suit specific project requirements. Their durability and corrosion-resistant properties, often enhanced by zinc plating or other coatings, make them suitable for both indoor and outdoor use.
