The Simpson HUC616TF HUCTF Top-Flange Concealed-Flange Joist Hanger is a heavy-duty hybrid hanger engineered for 6x16 nominal lumber, combining the advantages of both face-mount and top-mount hanger designs into a single, versatile connector. Two concealed flanges make it purpose-built for end-of-wall or corner installations where exposed hardware is not desirable, while face-nailing allows the hanger to be securely attached to the member for a clean, structurally sound connection. Built from 12-gauge steel with a G90 zinc galvanized coating, this hanger is designed to deliver lasting performance in demanding structural framing applications.

Key Features

• Hybrid face-mount and top-mount hanger design - gives installers the flexibility of both mounting styles in a single connector, reducing the need for multiple hanger types on complex framing projects
• Two concealed flanges - keep hardware out of sight at end-of-wall and corner connections, producing a cleaner finish where aesthetics matter alongside structural performance
• Face-nailing attachment - allows the hanger to be securely fastened directly to the member, providing a reliable, positive connection without relying on top-flange nailing alone
• 12-gauge steel construction - delivers the heavy-duty strength required for supporting 6x16 nominal lumber members in structural framing applications
• G90 zinc galvanized coating - provides corrosion resistance suited to demanding interior and protected exterior framing environments
• Slope capability up to 45 deg. - accommodates angled framing conditions without requiring a separate sloped hanger, adding versatility to a single product
• Tested, load rated, and code compliant - gives builders and inspectors confidence that the connection meets recognized structural standards without additional verification
• Rough beam sizes available by special order - means the HUCTF series can be adapted beyond standard nominal sizing when project requirements call for it

Why This Product

• One hanger, two mounting advantages - the hybrid design merges face-mount and top-mount functionality, so contractors working on end-of-wall or corner framing get the structural benefits of both approaches without sourcing separate connectors
• Concealed flanges for professional results - unlike standard face-mount hangers with visible side flanges, the HUCTF keeps hardware hidden at the connection point, making it a practical choice where finish quality is as important as load performance
• Built and rated for heavy structural loads - 12-gauge steel construction combined with a high nail count of 28 total fasteners means this hanger is sized and specified for the real demands of 6x16 structural lumber connections, not light-duty framing
• Slope versatility without added complexity - support for slopes up to 45 deg. is built into the hanger design, allowing use across a wider range of framing layouts without requiring custom or special-angle hardware
