The Simpson LUS24Z LUS ZMAX Galvanized Face-Mount Joist Hanger for 2x4 from Simpson is an economical, easy-to-install connector engineered to provide reliable support underneath 2x4 joists, rafters, and beams at the face-mount connection point. Built from 18-gauge steel with a ZMAX galvanized finish, this hanger is purpose-built for exterior framing and treated-wood applications where standard coatings may fall short. The patented double-shear nailing design sets it apart by distributing load through two points on each joist nail, delivering greater strength while actually reducing the total number of fasteners required.

Key Features

• Patented double-shear nailing design provides greater strength with fewer nails - load is distributed through two points on each joist nail, so you get a stronger connection without driving extra fasteners, saving time and labor on every install.
• Speed prongs for fast and easy installation - the hanger holds itself in position during placement, freeing both hands and keeping the workflow moving efficiently on the job site.
• Angled joist nailing easier in tight spaces - the angled nail slots let you drive fasteners at an accessible angle even where a straight-on approach is restricted, reducing awkward maneuvering in confined framing situations.
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - the heavy ZMAX coating holds up against moisture and the corrosive preservatives found in ACQ-treated lumber, where standard galvanized hardware degrades more quickly.
• Made from 18-gauge steel - the heavier steel construction contributes to the hanger's load-bearing capacity and long-term structural integrity across residential and light commercial framing projects.
• Nominal joist size: 2x4 - sized precisely for standard 2x4 dimensional lumber, ensuring a snug, code-consistent fit without shimming or field modification.
• Do not bend or remove tabs - the tabs are integral to the hanger's engineered performance, so leaving them intact ensures the connection meets its rated load values as designed.

Why This Product

• Fewer fasteners, faster completion - the patented double-shear nailing design means each nail works harder, so the same strong connection is achieved with a reduced nail count, cutting installation time without sacrificing structural performance.
• Built for harsh and treated-wood environments - the ZMAX galvanized finish provides a level of corrosion protection that goes beyond standard galvanizing, making this hanger a dependable choice for exterior decks, pergolas, and any framing that contacts ACQ or similarly corrosive treated lumber.
• Engineered for ease on the job - speed prongs that self-position the hanger plus angled joist nail slots combine to make installation straightforward even in tight framing bays, reducing the physical difficulty and time associated with common face-mount connections.
• Versatile fit for common framing applications - sized for standard 2x4 dimensional lumber and compatible with both Simpson Strong-Drive SD Connector screws and SCN Smooth-Shank Connector nails, this hanger works within fastener systems many crews already carry, keeping the connection flexible without requiring specialty hardware.

Frequently Asked Questions

What fasteners should be used to install the LUS24Z?

Install with Simpson Strong-Tie Strong-Drive SD Connector screws: (4) #9 x 1-1/2 in. screws in the header AND (2) #9 x 2-1/2 in. screws in the joist, OR (6) 0.148 in. x 3 in. Strong-Drive SCN Smooth-Shank Connector nails (Models: SD9112, SD9212, 10DHDG).

What is the benefit of the double-shear nailing design on the LUS24Z?

The patented double-shear nailing design distributes the load through two points on each joist nail, resulting in greater strength. This allows for fewer nails, faster installation, and the use of all common nails for the same connection.

Why is ZMAX galvanization important for this hanger?

ZMAX galvanization provides extra corrosion resistance, making the LUS24Z suitable for exterior applications and use with treated wood - including lumber treated with ACQ and other corrosive preservatives that can degrade standard galvanized finishes more rapidly.

Can the tabs on the LUS24Z be bent or removed during installation?

No. The tabs on the LUS24Z must not be bent or removed. Modifying the tabs can compromise the structural integrity and load-rated performance of the hanger. Always follow Simpson Strong-Tie installation guidelines and use all specified fasteners.
