Key features of no wrench screw anchor
These features help to ensure the no wrench screw anchors to have the widespread popularity. This is due to their versatility, durability and ease of installation. The following are the key factors of the no wrench screw anchors.
- Helical design – they have a helical design that allows the anchor to screw into the ground without the need for wrench. The helix efficiently penetrates the soil to create a strong and reliable grip as it rotates deeper into the ground.
- Ease of installation – no wrench screw anchors install by turning them directly into the ground. This helps to reduce the labor costs and installation time which makes them a more efficient and cost-effective solution.
- Versatility – they are compatible with a wide range of soil types including loose, compact and rocky soils. They install at various angles to accommodate different pole configurations and terrains. This also makes them adaptable in a wide range of ground conditions.
- Durability – they are from galvanized steel to provide excellent corrosion resistance. This protects the anchor from rust, corrosion and degradation to ensure the longevity. This is especially in areas with high moisture or exposure to chemicals.
- Load bearing capacity – no wrench screw anchors are available in various sizes and configurations. This offers a range of load-bearing capacities to suit different applications.
- Minimal soil disturbance – the anchors reduce soil disturbance as compared to traditional anchors. The helical design allows the anchor to penetrate the soil without causing displacement. This is important to reduce the impact on surrounding vegetation and the environment.
Selection and installation of no-wrench screw anchor
