The Simpson LUS46Z LUS ZMAX Galvanized Face-Mount Joist Hanger from Simpson is an economical, easy-to-install connector engineered to provide strong, reliable support underneath joists, rafters, and beams in both interior framing and demanding exterior environments. Built from 18-gauge steel with a ZMAX galvanized finish, this widely used face-mount hanger is designed for solid sawn lumber framing with common 4x6 and 4x8 lumber sizes, making it a practical choice for decks, floor systems, and roof assemblies where a dependable, corrosion-resistant connection is essential.

Key Features

• Patented double-shear nailing design - distributes the load through two points on each joist nail, delivering greater connection strength while requiring fewer nails and speeding up the installation process
• Speed prongs - hold the hanger in position during placement so installers can work faster without a second set of hands to steady the connector
• Angled joist nailing - allows fasteners to be driven at an angle, making it easier to complete nailing in confined or tight framing spaces without sacrificing holding power
• ZMAX galvanized coating - provides extra corrosion resistance beyond standard galvanization, keeping the connection reliable in exterior settings and applications involving treated lumber
• 18-gauge steel construction - offers a sturdy, production-proven build suited to common lumber framing loads without adding unnecessary bulk to the connection point
• Compatible with common fasteners - accepts Simpson Strong-Tie Strong-Drive SD Connector screws or Strong-Drive SCN Smooth-Shank Connector nails, so installers can work with fasteners they may already have on site
• Tabs must not be bent or removed - preserving the factory tab configuration maintains the rated performance of the hanger, protecting the structural integrity of the connection

Why This Product

• Fewer nails, faster work, no loss of strength - the patented double-shear nailing geometry means each nail does more work, so contractors can drive fewer fasteners per connection and still meet load requirements, cutting labor time on repetitive framing tasks
• Built for treated-wood and exterior framing - the ZMAX finish is specifically suited for environments where standard galvanized hardware degrades prematurely, giving builders confidence that the connection will hold up over time in decks, pergolas, and other exposed structures
• Fits common lumber dimensions without modification - designed for nominal 4x6 and 4x8 solid sawn lumber, this hanger drops into everyday framing situations without cutting, bending, or field-fabricating, keeping projects on schedule
• Economical connector from a trusted structural hardware brand - Simpson's LUS series is a widely used, field-proven hanger line, giving buyers a cost-effective solution that does not require trading performance for price on standard face-mount joist connections

Frequently Asked Questions

What is the double-shear nailing design and why does it matter?

The patented double-shear nailing design distributes the load through two points on each joist nail rather than one. This results in greater connection strength while requiring fewer nails overall, which also speeds up installation without sacrificing performance.

What fasteners should be used to install the LUS46Z?

Install with Simpson Strong-Tie Strong-Drive SD Connector screws: (4) #9 x 1-1/2 in. screws in the header AND (4) #9 x 2-1/2 in. screws in the joist, OR (8) 0.162 in. x 3-1/2 in. Strong-Drive SCN Smooth-Shank Connector nails (Models: SD9112, SD9212, 16DHDG). Always use all specified fasteners per the load tables.

Why is ZMAX galvanization important for this hanger?

ZMAX galvanization provides extra corrosion resistance compared to standard galvanized coatings. This makes the LUS46Z especially suitable for exterior environments and applications involving treated wood, where standard hardware may be prone to premature corrosion.

Can the tabs on the LUS46Z be bent or removed during installation?

No. The product data is clear: do not bend or remove the tabs on the LUS46Z. Modifying the tabs can compromise the structural integrity and load-rated performance of the hanger. Joist nails must be driven at an angle through the joist or truss into the header to achieve the rated table loads.
