Outer hexagonal French concrete self-tapping anchor bolts, also known as cement self-cutting expansion screws, are specialized fasteners designed for securing objects to concrete, brick, or block walls. These bolts are engineered to provide a strong and reliable connection in heavy-duty applications.
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:
Self-Tapping and Self-Drilling: These screws have a serrated cutting thread that cuts into the concrete as they are screwed in, providing a tight and secure fixing without the need for pre-drilling or tapping.Hexagonal Head: The hexagonal head provides a large bearing surface, allowing for easier driving and tightening of the screw.Corrosion Resistance: Often coated with protective finishes like zinc plating or other treatments, these screws resist rust and corrosion, making them suitable for outdoor use.High Tensile Strength: Made from materials like carbon steel or stainless steel, these screws offer increased durability and resistance to wear.Versatile Applications: They are used in various construction applications, including ventilation systems, sanitary installations, electrical installations, and attaching steel structures.
Scope of Application
Construction: Used in construction projects for securing materials like formwork, safety barriers, and drywall tracks to concrete or masonry structures.
Home Improvement: Ideal for DIY projects and home improvements, such as hanging shelves, mirrors, and other decorative items on masonry walls.
Outdoor Applications: Due to their corrosion resistance, these bolts are suitable for outdoor applications, such as securing outdoor furniture, lighting, or garden structures.
