The Simpson FWANZ ZMAX Galvanized Nail-On Foundation Wall Angle by Simpson Strong-Tie is engineered to connect the foundation or basement walls to the floor system, resisting out-of-plane forces imposed by soil pressure. The FWANZ fastens to the mudsill with nails, relying on other anchorage (by Designer) to anchor the sill plate to the foundation. Spacing of the FWA anchors is independent of the joist spacing, allowing for a multitude of options based on soil pressures - eliminating the need for costly cantilevered foundation designs.

Frequently Asked Questions

What is the primary function of the FWANZ Foundation Wall Angle?

FWA foundation anchors connect the foundation or basement walls to the floor system to resist out-of-plane forces imposed by soil pressure. The FWANZ fastens to the mudsill with nails, relying on other anchorage (by Designer) to anchor the sill plate to the foundation.

What floor system types is the FWANZ compatible with?

The FWANZ is compatible with solid sawn joists, I-joists and floor trusses, and testing has been performed on most common rim materials and types.

Why does the FWANZ feature ZMAX galvanization?

ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications, making the FWANZ well-suited for demanding environments where standard galvanization may be insufficient.

Does the spacing of the FWANZ anchor need to align with joist spacing?

No. Spacing of the FWA anchors is independent of the joist spacing, allowing for a multitude of options based on soil pressures. This flexibility simplifies layout and design for a wide range of project conditions.
