Cross large flat head self-tapping flat tail cutting screws are a type of self-tapping screw that is designed for applications where a large bearing surface and a flush finish are required. These screws are characterized by their large pan head, flat tail, and the ability to cut their own threads in the material being fastened.
Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.
Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.
Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.
Advantage:
Large Pan Head: Provides a large bearing surface, which helps prevent the material from sinking or cracking, especially in softer materials. It also offers a professional and finished look when installed.
Self-Tapping Capability: These screws can create their own threads in a predrilled hole, eliminating the need for pre-tapping, which saves time and effort.
Flat Tail Cutting: The flat tail allows the screw to sit flush with the material surface, providing a clean and finished look. The cutting feature enables the screw to cut through materials for a secure grip, making it suitable for use in a variety of materials, including metals, plastics, and composites.
Scope of Application
Electrical and Electronics: Secures components in electrical enclosures and control panels, as well as in the assembly of electronic devices where a low-profile appearance is desired.
Furniture and Cabinetry: Assembles wooden or composite materials in furniture and cabinetry, providing a secure and durable connection with a neat appearance.
Signage and Display: Used in the assembly of signs and displays where a flush finish is important for a clean look.
Machine and Equipment Assembly: In machinery and equipment assembly where a strong connection is needed, and the screw head should not protrude.
Aerospace and Marine: For lightweight and high-strength connections in aerospace and marine applications where corrosion resistance is also a factor.
