The Simpson HUCQ412-SDS Heavy Face-Mount Concealed-Flange Joist Hanger is built for structural connections that demand additional strength and safety factors, making it a dependable choice for heavy-duty framing projects where load capacity and code compliance are non-negotiable. Engineered by Simpson from 14-gauge steel with a G90 galvanized finish, this face-mount hanger accommodates a nominal 4x12 joist and features concealed header flanges that keep framing lines clean in exposed conditions. Installation is straightforward - the included Strong-Drive SDS Heavy-Duty Connector screws drive in without predrilling, delivering high-capacity connections to wood, masonry, or concrete bearing members.

Key Features

• Concealed header flanges - keep the hanger hidden behind the header for cleaner, more finished aesthetics in exposed framing applications
• 14-gauge steel construction - provides the structural integrity needed for connections requiring additional strength and safety factors
• G90 galvanized finish - resists corrosion, making this hanger suitable for demanding environments where long-term durability matters
• Tested, load rated, and code compliant - gives builders and inspectors confidence that every HUCQ-series connection meets established performance standards
• Strong-Drive SDS Heavy-Duty Connector screws included - no need to source fasteners separately, and no predrilling required, saving time on the job
• Installs to wood, masonry, and concrete - versatile enough to handle a wide range of structural bearing conditions on a single project
• Can be installed close to the end of the supporting beam - provides positioning flexibility that reduces layout constraints in tight framing situations

Why This Product

• No-predrill installation cuts labor time - the included Strong-Drive SDS Heavy-Duty Connector screws are engineered to drive directly into the framing member, eliminating a step and speeding up production framing without sacrificing holding strength
• Concealed flanges serve double duty - beyond aesthetics, the concealed-flange design allows placement close to beam ends, giving framers more flexibility in layout while still maintaining a clean look in visible structural applications
• Everything needed for installation is in the box - the hanger ships with all required SDS screws, so the connection can be completed with a single purchase and no additional fastener sourcing
• Built to code with documented load ratings - HUCQ-series hangers are tested and rated, supporting project approvals and inspections with traceable compliance data rather than field guesswork
