Big head screws are a specific type of fastener characterized by a larger head diameter compared to standard screws. This design feature provides a larger bearing surface, which helps distribute the load more evenly, particularly useful in applications requiring a strong hold in thin materials or for covering larger holes.
Material: These screws are often made from materials like stainless steel, carbon steel, aluminum, or even specialized plastics, depending on their intended use. Stainless steel is favored for its corrosion resistance, making it ideal for outdoor or humid environments.
Head Design: The enlarged head design can come in various shapes such as truss, button, or flange heads, each providing different aesthetic and functional advantages. The wide head helps in distributing pressure over a larger area, reducing the risk of material damage.
Drive Types: Big head screws can be equipped with various drive types, including Phillips, flat, Torx, or hex. Each drive type offers different benefits in terms of ease of installation and resistance to cam out.
Size and Length: While the head is larger, the body of the screw can vary significantly in diameter and length, allowing use in a variety of material thicknesses and for different strength requirements.
