AncrestScrew-in anchors
From the basic to the most elaborate, a complete product range with a long service life.
A screw-in anchor consists of a shaft and a helix. When force is exerted on the anchor, the ground above the helix becomes compact providing tensile resistance (extraction cone theory). The anchor is made of highly resistant material.
- The disc is designed with excellent rigidity and easy screw-in penetration.
- Depending on the model, the screw tightening torque is imposed on either the shaft or on the disc.
- The anchor's upper part is a function of the applied and imposed extraction forces.
Avantages
- Corrosion resistant thanks to galvanising and sacrificial material thickness.
- Immediate resistance.
- Saves time.
