Mechanical Screw Anchors
Screw anchors develop their load capacity by tapping into and creating an interlock between the anchor and the base material. In the most common systems, an undersized hole is drilled into the base material. As the anchor is driven in, a keying/friction force is developed between the shank of the anchor and the base material. This type of anchor can be suitable for sustaining light to heavy duty loads depending on the anchor design.
