Cross outer hexagonal head cavity self-tapping screws are a type of self-tapping fastener with a hexagonal outer drive, which provides a secure and tight connection in various materials.
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:
Hexagonal Drive: The hexagonal recess allows for a better grip and torque transfer, reducing the risk of the screwdriver slipping off during installation.
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 .
Versatility: Suitable for a wide range of materials, including metals, plastics, and composites, making them a versatile choice for various industries .
High Tensile Strength: Often made from high-strength materials like carbon steel or stainless steel, providing reliable strength and durability .
Scope of Application
Automotive Industry: Used for assembling interior trim panels, components, and body panels where the ability to form threads in plastics or sheet metals is beneficial .
Construction and HVAC: Ideal for fastening metal roofing, siding, and ductwork where a strong connection without pre-drilling is required .
Electrical and Electronics: Secures components in electrical enclosures and control panels, as well as in the assembly of electronic devices .
Furniture and Cabinetry: Assembles wooden or composite materials in furniture and cabinetry, providing a secure and durable connection .
Plumbing and Pipe Fitting: Used for securing metal and plastic pipes and fittings, streamlining the installation process .
