The Simpson HUCQ Heavy Concealed Flange Face-Mount Joist Hanger is a heavy-duty structural connector engineered for joist and beam connections that demand high-capacity performance and precise placement. Sized at 4 1/2 in. wide by 8 in. tall, this face-mount hanger is built from 14-gauge steel with a ZMAX coating and is designed to work exclusively with Simpson Strong-Drive SDS Heavy-Duty Connector screws - delivering a fast, reliable connection with no predrilling required. It is well suited for residential and commercial framing applications where structural integrity and installation flexibility are both critical.

Key Features

• Concealed Header Flanges - Flanges remain hidden after installation, allowing the hanger to be positioned close to the end of a supporting beam where standard hangers cannot be used, expanding placement options without sacrificing load capacity.
• 14-Gauge Steel Construction - Provides the structural rigidity needed for heavy-duty joist and beam connections in applications requiring additional strength and elevated safety factors.
• ZMAX Coating - Delivers enhanced corrosion resistance compared to standard galvanized finishes, making this hanger appropriate for demanding environments where long-term durability matters.
• Compatible with Simpson Strong-Drive SDS Screws - Designed exclusively for Simpson Strong-Drive SDS Heavy-Duty Connector screws, which require no predrilling, reducing installation time and labor on demanding job sites.
• Face-Mount Design - Attaches directly to the face of the header or beam, simplifying layout and alignment during framing and supporting efficient high-capacity connections in both residential and commercial construction.

Why This Product

• Engineered for tight or end-of-beam installations - The concealed flange design makes this hanger a practical solution when placement close to the end of a supporting beam is required and conventional hangers are not suitable for the application.
• Faster installation without predrilling - Pairing with Simpson Strong-Drive SDS Heavy-Duty Connector screws means crews can drive fasteners directly into the connection, cutting steps out of the installation process on time-sensitive projects.
• Built for high-demand structural applications - Sized and constructed specifically for structures requiring additional strength and elevated safety factors, this hanger is suited for heavy-duty framing work where connection reliability is non-negotiable.
• American-made quality with long-term corrosion protection - Backed by Simpson's ZMAX coating and domestic manufacturing, this connector is built to hold up in conditions where a standard finish would fall short.
