The Simpson HUC610Z HUC ZMAX Galvanized Face-Mount Concealed-Flange Joist Hanger for 6x10 is a heavy-duty structural connector engineered by Simpson for applications requiring additional strength and safety factors. Built for nominal 6x10 joist members, this face-mount hanger features concealed header flanges that deliver cleaner visible lines in exposed framing conditions - making it equally at home in finish-visible timber construction and demanding structural builds. The ZMAX galvanized coating provides superior corrosion resistance for exterior environments and structures utilizing pressure-treated lumber, while 14-gauge steel construction ensures the load capacity and rigidity that heavy framing connections demand.

Key Features

• Concealed header flanges - keep header connections hidden for cleaner, more finished aesthetics in exposed framing and architectural timber applications
• ZMAX galvanized coating - delivers extra corrosion resistance beyond standard galvanization, making this hanger well suited for exterior and treated-wood applications where long-term durability matters
• 14-gauge steel construction - provides the heavy-duty strength and rigidity required for structures where additional strength and safety factors are specified
• Extra optional triangle holes - allow additional fasteners to be installed where higher load capacity is needed, giving builders flexibility to meet elevated load requirements
• Compatible with wood, masonry, and concrete headers - broadens the range of job-site applications without requiring separate hardware for different substrate types
• Tested, load rated, and code compliant - takes the guesswork out of structural approvals, supporting faster plan review and inspection sign-off on permitted projects
• 5-1/2 in. seat width sized for 6x10 joists - ensures a precise, stable fit that eliminates seat shimming and keeps installation straightforward

Why This Product

• Built for demanding structural applications - the HUC610Z is specifically designed for structures requiring additional strength and safety factors, making it the right choice when standard hangers are not sufficient for the load or code requirements of the project
• Aesthetics and performance in one hanger - the concealed-flange design handles heavy structural loads while keeping header connections out of sight, a combination that matters on exposed beam and timber-frame projects where appearance cannot be sacrificed for strength
• ZMAX coating for long-term reliability - where standard zinc galvanization falls short in exterior or treated-lumber environments, the ZMAX finish provides the elevated corrosion protection needed to maintain structural integrity over the life of the build
• Versatile fastener compatibility and optional load-boosting holes - the hanger accepts both nails and Strong-Drive SD Connector screws, and the extra optional triangle holes mean load capacity can be increased without switching to a different product

Frequently Asked Questions

What is the nominal joist size this hanger is designed for?

The HUC610Z is designed for a nominal joist size of 6x10, with a seat width of 5-1/2 in.

What fasteners are recommended for installing the HUC610Z?

Installation requires (14-18) 0.162 in. x 3-1/2 in. nails in the header and (6-8) 0.162 in. x 3-1/2 in. nails in the joist, OR (26) #10 x 1-1/2 in. Strong-Drive SD Connector screws.

Why does the HUC610Z feature ZMAX galvanization?

ZMAX galvanization offers extra corrosion resistance, making this hanger well suited for exterior and treated-wood applications where standard galvanization may not provide sufficient protection.

What makes the HUC610Z a concealed-flange hanger?

The HUC610Z has concealed header flanges, which tuck behind the header rather than wrapping over the face, providing cleaner visible lines when installed in exposed framing conditions.
