Foundation Anchor

Changes to the international Building Code (IBC) and International Residential Code (IRC) have resulting in 5/8" diameter anchor bolts being more commonly specified on design plans for anchoring the structure to the concrete foundation. The FA4 foundation anchors can be installed as a replacement for these anchor bolts while achieving the same load capacity. They can also be used to replace 1/2" diameter anchor bolts. There are two FA4 Foundation Anchor design tables below. The first table list the allowable load capacity of the FA4. The second table list the equivalent spacing required to meet the prescriptive code requirement for 5/8" and 1/2" diameter anchor bolts that are called out on the plan as being spaced at 4-ft or 6-ft 0.C.
