The Simpson HU48Z HU ZMAX Galvanized Face-Mount Joist Hanger for 4x8 is a heavy-duty structural connector from Simpson engineered for framing applications where additional strength and safety factors are required. Built from 14-gauge steel with a ZMAX galvanized finish for superior corrosion resistance, this face-mount hanger delivers the tested, load-rated performance that engineers and contractors rely on for both residential and commercial construction. Designed to accept a nominal 4x8 joist, the HU48Z brings professional-grade reliability to any project that demands code-compliant structural connections.

Key Features

• Extra optional triangle holes for additional load - gives installers flexibility to increase load capacity when project conditions demand it, without requiring a different hanger size.
• Tested, load rated, and code compliant - the HU-series meets building code requirements, so contractors and inspectors can approve installations with confidence.
• Nominal 4x8 joist compatibility - sized specifically for 4x8 framing members, ensuring a precise, secure fit that supports proper load transfer.
• 3-9/16 in. seat width - matches the actual bearing surface of the joist for stable, consistent support at the connection point.
• 14-gauge steel construction - heavy-gauge material provides the structural integrity needed for demanding load-bearing applications.
• ZMAX galvanized coating - delivers extra corrosion resistance beyond standard galvanized finishes, making this hanger well suited for environments where moisture or treated lumber are factors.

Why This Product

• Engineered for demanding structural work - the HU-series is specifically designed for structures requiring additional strength and safety factors, meaning this hanger is built to perform where standard connectors may fall short.
• Enhanced corrosion protection as a standard feature - the ZMAX galvanized finish is not an upgrade option but a built-in characteristic of this model, providing long-term durability in corrosive conditions without extra cost or sourcing effort.
• Trusted by engineers and contractors - Simpson connectors are a go-to choice for building professionals, and the HU48Z carries the same tested, code-compliant pedigree that makes the brand a job-site standard for structural hangers and connectors.
• Versatile load options through optional triangle holes - the ability to add fasteners through the extra triangle holes lets builders tailor the connection to actual load requirements, adding value across a range of framing and structural applications.
