The Simpson HUC28-2Z HUC ZMAX Galvanized Face-Mount Concealed-Flange Joist Hanger for Double 2x8 is a heavy-duty structural connector engineered by Simpson for framing applications that demand additional strength and safety factors. Designed to face-mount double 2x8 wood joists to wood, masonry, and concrete headers, this hanger features concealed header flanges that keep visible lines clean in exposed framing conditions. Built from 14-gauge steel with a ZMAX galvanized finish, it is well-suited for exterior construction and treated-wood environments where corrosion resistance is a priority.

Key Features

• Concealed header flanges - keep structural hardware out of sight in exposed conditions, delivering a cleaner finished appearance without sacrificing performance
• ZMAX galvanized coating - provides extra corrosion resistance compared to standard galvanization, making this hanger reliable in exterior and treated-wood applications where moisture exposure is a concern
• 14-gauge steel construction - delivers the heavy-duty strength needed for structures requiring additional load capacity and safety factors
• Extra optional triangle holes - allow additional fasteners to be added where higher load demands call for it, giving installers flexibility to meet project requirements
• Compatible with wood, masonry, and concrete headers - reduces the need for multiple connector types across mixed-material framing applications
• Tested, load rated, and code compliant - gives builders and inspectors confidence that the hanger meets recognized performance and safety standards
• Seat width of 3-1/8 in. sized for double 2x8 joists - ensures a precise, stable fit that simplifies installation and supports consistent load transfer

Why This Product

• Cleaner aesthetics where structure is visible - the concealed flange design hides the header connection behind the framing member, making this hanger a practical choice for exposed beam and joist applications where appearance matters alongside structural performance
• Built for demanding environments - ZMAX galvanization goes beyond standard coatings to protect against corrosion in exterior framing, high-moisture settings, and projects using pressure-treated lumber
• Engineered for heavier structural loads - the HUC series is specifically designed for conditions requiring additional strength and safety factors, with optional triangle holes to accommodate higher fastener counts when load demands require it
• Versatile installation across multiple header materials - a single hanger handles connections to wood, masonry, and concrete, streamlining procurement and reducing the number of connector SKUs needed on complex framing projects
