The Simpson HUC410SS HUC Stainless-Steel Face-Mount Concealed-Flange Joist Hanger for 4x10 is a heavy-duty structural connector from Simpson engineered for framing applications that demand additional strength and safety factors. Its concealed header flanges keep connection hardware out of sight, producing cleaner visible lines in exposed framing conditions - a practical advantage wherever aesthetics matter alongside structural performance. Built from 14-gauge stainless steel, this face-mount hanger supports wood joist-to-wood, masonry, and concrete connections, and delivers the enhanced corrosion resistance required for exterior structures and treated-wood framing.

Key Features

• Concealed header flanges - hide hardware from view in exposed framing, giving finished, professional-looking results without sacrificing structural integrity
• 14-gauge stainless steel construction - provides the material thickness and corrosion resistance needed for exterior, high-moisture, and treated-wood applications where standard steel hardware can degrade prematurely
• Extra optional triangle holes - allow additional fasteners to be added when higher load capacity is needed, giving installers flexibility to meet demanding engineering requirements
• Tested, load rated, and code compliant - HUC-series hangers carry verified load ratings, supporting confident use on permitted projects and inspected structures
• Compatible with wood, masonry, and concrete headers - broadens the range of framing scenarios this single hanger can address, reducing the need to source multiple connector types
• Seat width sized for a 4x10 nominal joist - ensures a precise, stable fit for the supported member, minimizing on-site fitment issues and keeping installation straightforward
• Stainless-steel fasteners required at installation - maintains a fully corrosion-resistant connection from hanger to fastener, protecting long-term structural performance in demanding environments

Why This Product

• Built for high-demand structural applications - the HUC series is specifically designed for structures requiring additional strength and safety factors, making it a dependable choice when standard hangers do not meet engineering or code requirements
• Stainless steel throughout for lasting corrosion resistance - the all-stainless construction is suited to exterior decks, covered porches, and treated-lumber framing where moisture exposure makes corrosion protection a non-negotiable requirement
• Cleaner results in visible framing - the concealed-flange design keeps the header connection discreet, making this hanger well suited to open-ceiling interiors, exposed timber framing, and any project where the structure will remain visible after completion
• Versatile substrate compatibility with flexible load options - the ability to connect to wood, masonry, or concrete headers, combined with optional triangle holes for added load capacity, means this hanger adapts to a wide variety of project conditions without requiring a different product

Frequently Asked Questions

Why should I choose the stainless-steel version of the HUC410 hanger?

Stainless steel offers extra corrosion resistance compared to standard finishes, making the HUC410SS the appropriate choice for exterior applications, high-moisture environments, and installations involving treated wood, where standard steel hardware may be prone to accelerated corrosion.

What fasteners are required to install the HUC410SS?

Installation requires either (14-18) 0.162 in. x 3-1/2 in. ring-shank nails in the header and (6-10) 0.148 in. x 3 in. ring-shank nails in the joist, or (28) #10 x 1-1/2 in. Strong-Drive SD Connector screws. Because this hanger is stainless steel, stainless-steel fasteners are required.

What is the advantage of the concealed-flange design on the HUC410SS?

The concealed header flanges hide behind the header once installed, resulting in cleaner visible lines. This makes the HUC410SS particularly well-suited for exposed framing conditions where aesthetics matter alongside structural performance.

Is the HUC410SS tested and code compliant?

Yes. HUC-series hangers are tested, load rated and code compliant, ensuring they meet the structural requirements for applications where additional strength and safety factors are necessary.
