Carbon Steel GB/T 22795-2008 External Forced Expansion Anchor Bolt-Type WP
Product Overview:
External forced expansion anchor bolt - type WP is a fastener used in concrete structures. It is anchored by the interaction of the outer forcing tube and the conical outer forcing plug. This kind of anchor bolt is usually made of carbon steel, stainless steel and other materials, with high tensile strength and corrosion resistance. Common specifications include M6, M8, M10, M12 and M16, and the length and diameter vary according to the specific application requirements.
Grade:
4.8, 6.8, 8.8, 10.9, 12.9
Carbon Steel GB/T 22795-2008 External Forced Expansion Anchor Bolt-Type WP Details

Functional Characteristics
Application
Functional Characteristics
- Main structure: generally made of high-strength steel, with good tensile and shear properties; The ends are fitted with specially designed expansion devices such as conical sleeves, expansion claws or spring-loaded expansion rings.
- Expansion elements: These elements gradually expand outward during bolt tightening to increase the contact area with the hole wall and the holding force.
- Durability of the anti-corrosion coating: galvanized, nickel-plated or other anti-rust treatment layer to protect the bolt from corrosion.
Application
- Construction industry: Suitable for fixed ceiling fans, lamps, cabinets, air conditioning units and other heavy interior decoration.
- Industrial setup: For the installation of heavy machinery, conveyor systems, tank legs and line equipment.
- Public projects: as a key fixed means in the construction and maintenance of Bridges, tunnels, airport runways and highway signs.
- Civil engineering: Used in residential and commercial buildings to strengthen balconies, stair railings, anti-theft door and window frames and other structures.
