The Simpson 6 x 16 Concealed-Flange Heavy Face-Mount Hanger HUC616 is a heavy-duty structural connector engineered for projects that demand additional strength and elevated safety factors. Built to accept nominal 6x16 lumber, this face-mount joist hanger features concealed header flanges that produce cleaner, more finished visible lines in exposed framing conditions - making it equally suited to utilitarian load-bearing applications and settings where the framing itself is on display. Fabricated from 14-gauge steel with a G90 zinc galvanized finish, it delivers the durability and load capacity that demanding structural connections require, whether the supporting member is wood, masonry, or concrete.

Key Features

• Concealed header flanges - keep the connection profile low-profile and visually clean, ideal for exposed framing where aesthetics matter alongside structural performance
• 14-gauge steel construction - provides the heavy-duty rigidity needed for structures requiring additional strength and elevated safety factors
• G90 zinc galvanized finish - delivers extra corrosion resistance for longevity in demanding job-site and service environments
• Extra optional triangle holes - allow additional nailing for increased load capacity when project conditions call for it
• Tested, load rated, and code compliant - gives builders and inspectors confidence that the connection meets recognized structural standards
• Compatible with wood, masonry, and concrete headers - provides flexibility to use a single hanger solution across a variety of structural assemblies
• 5-1/2 in. seat width for nominal 6x16 lumber - ensures a precise, secure cradle fit that keeps the joist properly positioned and supported

Why This Product

• Structural performance where it counts most - the HUC series is specifically designed for structures requiring additional strength and safety factors, making this hanger a dependable choice for heavy framing loads that standard hangers are not rated to handle
• A cleaner finish in exposed applications - the concealed flange design sets this face-mount hanger apart in finished or visible framing conditions, eliminating the rough appearance of exposed flanges without compromising connection integrity
• Broad substrate compatibility - the ability to connect wood joists to wood, masonry, or concrete headers means this single hanger works across multiple construction scenarios, reducing the need to source different connectors for different assemblies
• Built-in flexibility for higher load demands - the optional triangle holes give installers a straightforward path to additional load capacity using the same hanger, avoiding the need to upsize or switch products when load requirements increase
