Where do anchor bolts go in concrete?
If you are using anchor bolts for concrete slabs or foundations it’s important to place the bolt in the concrete so it’s in the center of the wall. For 2 x 6 walls, the bolt would be 2 3/4 inches from the outer edge and for 2 x 4 walls the anchor bolt would be 1 3/4 inches from the edge.
