The Simpson HUC44 Heavy Concealed-Flange Face-Mount Joist Hanger is a heavy-duty structural connector engineered by Simpson for framing applications that demand additional strength and safety factors. Built to support nominal 4x4 lumber members, this face-mount hanger features concealed header flanges that keep visible lines clean and finished in exposed framing conditions - making it a practical choice for both structural performance and aesthetics. Fabricated from 14-gauge steel with a G90 zinc galvanized coating, the HUC44 is tested and load rated for connecting wood joists to wood, masonry, and concrete structures with confidence.

Key Features

• Concealed header flanges - tuck out of sight behind the header to deliver cleaner, more finished visible lines in exposed framing applications where appearance matters
• Extra optional triangle holes - allow installers to drive additional nails when greater load capacity is needed, providing flexibility to meet specific structural requirements without swapping hangers
• Tested, load rated, and code compliant - the HUC series meets established safety standards, giving builders and inspectors confidence that the connection performs as engineered
• Compatible with wood, masonry, and concrete headers - broad substrate compatibility reduces the need to source different hangers across mixed-material framing scenarios
• 14-gauge steel construction - delivers the heavy-duty rigidity required for structures with elevated strength and safety factor demands
• G90 zinc galvanized finish - provides a layer of corrosion resistance suited for applications where moisture exposure is a concern

Why This Product

• Heavy-duty performance where standard hangers fall short - the HUC44 is specifically designed for structures requiring additional strength and safety factors, making it the right choice when a standard-duty hanger is not engineered for the load demands of the project
• Cleaner results in exposed framing - the concealed-flange design hides the header connection from view, so structural hardware does not detract from the finished look of visible ceiling or beam work
• Built-in load flexibility through optional triangle holes - rather than requiring an entirely different connector, installers can add nails through the extra triangle holes to increase load capacity on the spot, adapting to real-world site conditions
• Versatile enough for multiple substrate types - rated for wood-to-wood, wood-to-masonry, and wood-to-concrete connections, this single hanger covers a range of common framing scenarios without requiring separate product selections for each application

Frequently Asked Questions

What size lumber is the HUC44 designed to support?

The HUC44 is designed for a nominal joist size of 4x4, with a seat width of 3-9/16 inches to properly cradle that member size.

What types of fasteners should be used to install the HUC44?

Install with 0.162 in. x 3-1/2 in. nails in the header and 0.148 in. x 3 in. nails in the joist for a properly rated connection.

Why does the HUC44 have optional triangle holes?

The extra optional triangle holes allow installers to add additional nails when greater load capacity is needed, providing flexibility to meet specific structural load requirements.

Is the HUC44 suitable for use in corrosive or outdoor environments?

The HUC44 is coated with a G90 zinc galvanized finish, which provides a layer of corrosion resistance appropriate for many construction environments. Always consult applicable building codes and project specifications to confirm suitability for your specific conditions.
