Screw Anchor​

1. Single and intermittent threads.

• Enlarge thread pitch to raise tensile strength

 

2. Low helix angle design

• Low driving torque to save labor

• High clamping force to avoid loose during shaking

 

3. Asymmetrical thread peak design

• When thread peak bears pull, it results in the effect of transverse push and press to enhance tensile strength

 

4. 2-3 lead threads design

• Without any spinning at the first insertion time

• Time-saving and stability
