Anchor Bolts Expansion Screw for Construction and Industrial Use

Understanding Anchor Bolts Expansion Screw Technology

Anchor Bolts Expansion Screw systems are mechanical fastening solutions designed to secure structural components into solid base materials such as concrete, masonry, and brick. By expanding within pre-drilled holes, these screws generate radial pressure that ensures high load-bearing stability and long-term anchoring performance.

In construction, infrastructure, and industrial installation projects, expansion anchor technology is widely used where vibration resistance, pull-out strength, and installation efficiency are critical factors.

Key Types of Anchor Bolts Expansion Screw

Heavy Duty Expansion Screws

Designed for high load and structural applications
Commonly used in steel structures and machinery installation
Often manufactured with reinforced sleeves

heavy duty anchor bolts expansion screw solutions are preferred where safety margins and long-term stability are essential.

Feature	Standard Expansion Screw	Heavy Duty Expansion Screw
Load Capacity	Medium	High
Application	Light fixtures	Structural supports

Concrete Expansion Screws

Optimized for dense concrete substrates
Strong frictional engagement
Reliable performance under compressive stress

concrete anchor bolts expansion screw designs ensure consistent anchoring in reinforced and non-reinforced concrete structures.

Base Material	Brick	Concrete
Holding Strength	Moderate	High
Recommended Screw Type	Plastic Expansion	Concrete Expansion

Stainless Steel Expansion Screws

Excellent corrosion resistance
Suitable for humid or outdoor environments
Stable mechanical performance

stainless steel anchor bolts expansion screw products are widely used in coastal, industrial, and architectural applications requiring durability.

Plastic Expansion Anchor Screws

Lightweight and cost-effective
Ideal for door and window installation
Compatible with multiple screw materials

plastic expansion anchor screw for construction is commonly applied in aluminum alloy doors, windows, and interior decoration systems.
