Simpson Strong-Tie ZMAX Galvanized Face-Mount Concealed-Flange Joist Hanger for 2x6 (LUC26Z)
Simpson Strong-Tie ZMAX Galvanized Face-Mount Concealed-Flange Joist Hanger for 2x6 (LUC26Z)
Key Features
Overview
The Simpson Strong-Tie LUC26Z concealed-flange joist hanger is a face-mount wood connector designed to support nominal 2x6 and 2x8 members. This is a joist hanger designed for supporting joists, rafters, or beams from a carrying member while keeping the header flanges hidden for a cleaner finished look. Model Number: LUC26Z.
What makes this hanger different from a basic face-mount hanger is the concealed-flange layout. Instead of leaving wide side flanges visible on the front of the carrying member, the LUC26Z keeps those flanges tucked back. On exposed framing, pergolas, and deck details where appearance matters, that gives you a much cleaner line without giving up a tested structural connection.
Simpson Strong-Tie builds the LUC26Z from 18-gauge steel and finishes it with ZMAX coating. In practical terms, that means the connector is made for real framing work and is better suited for exterior conditions and treated-wood applications than a plain unfinished hanger. If you are framing outdoors or working with pressure-treated lumber, the finish is not just a spec on paper, it is part of the reason to choose this exact model.
The hanger is load rated and code compliant, and Simpson publishes tested allowable loads based on the approved fastener schedule and wood species. For the LUC26Z, published values vary by fastener choice, with allowable loads reaching up to 1,300 pounds and uplift values up to 1,035 pounds when installed with specified Simpson Strong-Drive fasteners. That matters because you are not guessing what the hanger can do. You are working from an engineered connector with known performance.
Installation flexibility is another strong point. Simpson notes that the LUC series installs using several fastener selections with tested allowable loads, including Strong-Drive SD connector screws. That gives contractors options when they want a cleaner install, easier driving, or a fastening method aligned with the rest of the job. The published notes also call out that joists sloped up to 1/4:12 achieve table loads, and that end-grain nailing into a solid sawn carrying member requires an allowable-load reduction factor of 0.67. Those are the kinds of details that matter when you are building from plans instead of just hanging lumber by eye.
Dimensionally, the LUC26Z is sized for nominal 2x6 and 2x8 lumber, with a listed width of 1-9/16 inches, height of 4-3/4 inches, and seat dimension of 1-3/4 inches. That compact profile helps when you need concealed support without stepping up to a bulkier hanger than the application calls for. Lowe's also lists actual dimensions at about 1.659 inches wide, 4.798 inches long, and 1.906 inches deep, which lines up with the published engineering table.
This connector is a strong fit for deck builders, carpenters, remodelers, and general contractors who want a structural hanger that does not draw attention to itself. It also makes sense for serious DIY users working on pergolas, porch framing, or repair work where exposed hardware would look out of place. If the job calls for a concealed-flange hanger for nominal 2x6 or 2x8 members, this is the right style of connector to be looking at.
Cleaner Exposed Framing
The concealed-flange design is the whole point here. You get the support of a face-mount joist hanger, but with a much cleaner look when the framing stays visible.
- Designed to support the joist, rafter, or beam from underneath
- Concealed header flanges reduce visible hardware in exposed conditions
Built for Exterior and Treated Lumber Work
This hanger is not just about shape. The 18-gauge steel body and ZMAX finish are what make it a practical connector for deck framing, outdoor repairs, and other treated-wood applications.
- Made from 18-gauge steel
- ZMAX coating adds corrosion resistance for exterior and treated-wood use
Multiple Approved Fastening Options
Simpson publishes tested allowable loads with more than one approved fastener schedule, which gives you flexibility without stepping outside the connector data. That is useful when you prefer structural connector screws over traditional nails.
- Published for specified Strong-Drive SD connector screw schedules
- Allowable loads vary by fastener choice and wood species

Pro Tip
If you are fastening into the end grain of a solid sawn carrying member, Simpson notes the allowable load gets reduced by a factor of 0.67. Check that before you treat the published table loads as a direct one-to-one match for your job.

- Why it stands out: The concealed flange design looks better than a standard face-mount hanger, and the published load data plus approved fastener options make it a real structural connector, not just a cosmetic choice.
- Worth knowing: Fasteners are not included, so make sure you match the installation to Simpson's specified schedule if you want the listed performance.
Common Questions
- What lumber sizes does the LUC26Z fit? It is sized for nominal 2x6 and 2x8 members.
- Is this hanger suitable for exterior or treated-wood applications? Yes. The ZMAX finish is intended to provide extra corrosion resistance for exterior and treated-wood use.
- Can this hanger be installed with connector screws? Yes. Simpson publishes tested allowable loads for specified Strong-Drive SD connector screw schedules, including SD9112 and SD10112 options.
