Simpson Strong-Tie LUS210Z 18-Ga 2x10 ZMAX U-Shaped Joist Hanger 3-Pack Galvanized The Simpson Strong-Tie LUS210Z is an 18-gauge, ZMAX-galvanized U-shaped joist hanger engineered for secure, code-compliant support of double 2x10 or double 2x12 joists in residential and light commercial framing. Featuring patented double-shear nailing, it distributes load through two contact points per nail, significantly increasing connection strength while reducing the total number of fasteners required. The hanger accommodates standard 10d nails or #10 x 2-1/2" Strong-Drive SD9 structural screws for versatile, tool-efficient installation. Angled joist nail slots simplify driving in tight spaces, while integrated speed prongs ensure quick, accurate alignment on the header during assembly. The G-185 ZMAX coating provides enhanced corrosion resistance, making it suitable for exterior applications and use with pressure-treated lumber.

Product Application This joist hanger is used by framers, builders, and contractors in residential deck, floor, and roof systems where reliable, high-strength connections between joists and headers are required. It is commonly installed in outdoor decks, porch floors, and interior floor assemblies using pressure-treated or kiln-dried lumber. The ZMAX coating makes it especially suited for damp or coastal environments where corrosion resistance is critical. The double-shear design reduces labor time while meeting or exceeding IRC and IBC load requirements, ensuring structural safety without over-engineering. Trusted on job sites nationwide, the LUS210Z delivers speed, strength, and long-term durability in wood-frame construction where performance and code compliance are non-negotiable.
