MiTek Releases the New FA4 Foundation Anchor, Offering an Alternative to Anchor Bolts for Sill Tie-Downs

The International Building Code and International Residential Code now commonly require the use of 5/8" diameter anchor bolts on design plans for anchoring a structure to its foundation. The FA4 Foundation Anchor may be installed as a replacement for these anchor bolts, while achieving the same load capacity. In addition, FA4 Foundation Anchors may be installed in wet concrete. Once the concrete cures, mudsills can be put in place and secured by bending the FA4 flanges for a tight fit and then nailing the FA4 in place with the size and quantity of fasteners specified by USP. For replacing 1/2” diameter anchor bolts, fewer FA4 Foundation Anchors would be required than the number needed to replace 5/8" anchors bolts, further driving down product and installation costs.

The FA4 can also be mounted to a form board before concrete is poured.“The specification of 5/8" and 1/2” anchor bolts is costly, to say nothing of the labor-intensive task of embedding them in concrete and bolting down the mud sill,” said Steve Brekke, P.E., Engineering Operations Manager for USP. ”The FA4 offers a cleverly designed alternative that can save both money and time.”
