The Simpson LUS28-3Z LUS ZMAX Galvanized Face-Mount Joist Hanger for Triple 2x8 by Simpson is an economical, easy-to-install connector engineered for face-mount joist and rafter connections using triple 2x8 and triple 2x10 lumber. Built from 18-gauge steel with a ZMAX galvanized finish, this hanger is purpose-built for exterior framing and treated-wood applications where corrosion resistance is critical. Its patented double-shear nailing design distributes the load through two points on each joist nail, delivering a stronger connection with fewer fasteners and faster installation time.

Key Features

• Patented double-shear nailing design - distributes load through two points on each joist nail, giving you greater connection strength while requiring fewer nails overall
• Speed prongs - hold the hanger in position hands-free during installation, saving time and reducing frustration on the job
• Angled joist nailing - allows fasteners to be driven more easily in confined or tight framing spaces where straight-on access is limited
• ZMAX galvanized coating - provides extra corrosion resistance beyond standard galvanized finishes, making this hanger a reliable choice for exterior use and connections involving ACQ or other treated lumber
• 18-gauge steel construction - delivers a sturdy, durable hanger sized and rated for the demands of triple 2x8 and triple 2x10 framing members
• Compatible with all common nails and Strong-Drive fasteners - works with widely available fastener options, including Strong-Drive SD Connector screws and SCN Smooth-Shank Connector nails, for flexible installation
• Tabs must not be bent or removed - preserving the tabs as designed ensures the hanger performs to its rated capacity and maintains a safe, code-compliant connection

Why This Product

• Strength where it counts most - the patented double-shear nailing design is not a standard feature on every hanger; it actively increases load capacity per nail, so you get a higher-performing connection without driving extra fasteners into crowded framing
• Built for treated-wood and outdoor framing - the ZMAX galvanized finish is specifically formulated for applications involving ACQ-treated lumber and exterior exposure, where a standard galvanized coating would be insufficient and potentially degrade over time
• Faster, easier installation on complex assemblies - speed prongs and angled joist nailing work together to make positioning and fastening a triple-member hanger more manageable, especially in tight bays or overhead installations where every second and inch of access matters
• Versatility across two nominal lumber sizes - rated for both triple 2x8 and triple 2x10 members, this single hanger covers multiple common framing configurations, reducing the number of SKUs you need to keep on hand for multi-size projects

Frequently Asked Questions

What fasteners should be used to install the LUS28-3Z?

Install with Simpson Strong-Tie Strong-Drive SD Connector screws: (6) #9 x 1-1/2 in. screws in the header AND (4) #9 x 2-1/2 in. screws in the joist, OR (10) 0.162 in. x 3-1/2 in. Strong-Drive SCN Smooth-Shank Connector nails (Models: SD9112, SD9212, 16DHDG).

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 increases connection strength while allowing fewer nails to be used, which speeds up installation without sacrificing performance.

Why is ZMAX coating used on this hanger?

ZMAX galvanization provides extra corrosion resistance beyond standard galvanized coatings. This makes the LUS28-3Z suitable for exterior applications and installations involving treated lumber, where standard coatings may degrade more quickly due to chemical exposure or moisture.

Can the tabs on the LUS28-3Z be bent or removed for easier fitting?

No. The product data explicitly states that the tabs must not be bent or removed. Modifying the tabs can compromise the structural integrity of the connection and void the load rating of the hanger.
