The forces on a Machine Screw Anchor are transferred to the base material that it is installed in.
If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchor.

When vibration or sudden impact are part of the load conditions, spacing between anchors should be increased.
