Cross countersunk inner expansion bolts typically have a cross-slotted head and a countersunk head design that allows the head of the bolt to be either flush with or below the surface of the installation. This design allows the bolts to have a clean appearance after installation while providing a stable hold. They are commonly used in areas such as interior decorating, furniture manufacturing, and structural fixing of buildings.
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:
Aesthetics: The countersunk head design allows the head of the bolt to be flush with the mounting surface, providing a neat appearance. HIGH STRENGTH: Typically made of high-strength steel, capable of withstanding high tensile and shear forces. Quick Installation: Cross-groove design allows for quick installation with common tools. Wide applicability: Suitable for a wide range of materials including concrete, brick, wood and metal. Corrosion Resistant: Some models are made of stainless steel for wet or corrosive environments.
Scope of Application
Interior Decoration: Used to secure upholstery, hang paintings or mirrors, and other applications where concealed bolt heads are required.
Furniture Manufacturing: In furniture assembly, used to secure panels and structural components, providing a sturdy connection.
Building structures: In construction, for fixing windows, door frames, brackets and other structural components.
Mechanical Installation: Used to secure machine bases, pipes and other equipment to ensure their stability and safety.
