The Simpson HUC210-3Z HUC ZMAX Galvanized Face-Mount Concealed-Flange Joist Hanger for Triple 2x10 is a heavy-duty structural connector engineered by Simpson for applications requiring additional strength and safety factors. Built from 14-gauge steel with a ZMAX galvanized finish, this face-mount hanger connects triple 2x10 wood joists to wood, masonry, and concrete headers while keeping header flanges hidden from view - an advantage wherever framing is left exposed. Whether used in exterior construction, treated-wood environments, or high-load structural assemblies, this hanger delivers the tested performance and code compliance that demanding projects require.

Key Features

• Concealed header flanges - keep the hanger hidden behind the header for cleaner, more finished visible lines in exposed framing conditions
• ZMAX galvanization - offers extra corrosion resistance compared to standard coatings, making this hanger well suited for exterior applications and use with treated wood where moisture and chemical exposure are concerns
• 14-gauge steel construction - provides the structural mass needed to meet the additional strength and safety factors required by heavy-load framing designs
• Extra optional triangle holes - allow additional fastening points when a project calls for increased load capacity beyond the standard nailing pattern
• Compatible with wood, masonry, and concrete headers - gives builders flexibility to use a single connector type across multiple header materials on the same job
• HUC-series hangers are tested, load rated, and code compliant - provides the documentation and confidence needed for inspections and engineered applications
• Installs with nails or Strong-Drive SD Connector screws - lets crews choose the fastener type that fits their tools and workflow without sacrificing structural integrity

Why This Product

• Strength built for the hardest jobs - the HUC series is specifically designed for structures requiring additional strength and safety factors, so builders working on demanding or engineered assemblies get a connector rated for the task rather than one adapted from a lighter-duty line
• Aesthetics without sacrifice - the concealed header flange design eliminates the visual bulk of exposed flanges in finished or semi-finished spaces, letting contractors meet both structural and appearance requirements with one product
• Long-term durability in harsh conditions - ZMAX galvanization delivers extra corrosion resistance beyond standard galvanized coatings, protecting the connection in exterior environments and alongside treated lumber where premature corrosion is a real concern
• Flexible installation options - acceptance of both nail and Strong-Drive SD Connector screw fastening patterns means this hanger fits standard framing workflows and adapts easily when project conditions or crew preferences change

Frequently Asked Questions

What type of fasteners are required to install the HUC210-3Z?

The HUC210-3Z can be installed using (14-18) 0.162 in. x 3-1/2 in. nails in the header and (6-10) 0.148 in. x 3 in. nails in the joist, or alternatively with (28) #10 x 1-1/2 in. Strong-Drive SD Connector screws.

What makes the ZMAX coating different from standard galvanization?

ZMAX galvanization offers extra corrosion resistance compared to standard coatings, making the HUC210-3Z particularly well suited for exterior applications and use with treated wood where moisture exposure and chemical contact are concerns.

What is the purpose of the concealed header flanges on the HUC210-3Z?

The concealed header flanges on this face-mount hanger are designed to provide cleaner, more refined visible lines in exposed framing conditions, making the connection point less obtrusive when the structural members remain visible in the finished space.

Are the HUC-series hangers code compliant?

Yes, HUC-series hangers are tested, load rated, and code compliant, providing confidence in their performance for structures requiring additional strength and safety factors. The optional triangle holes also allow for additional load capacity when needed.
