The Simpson HU46 HU Galvanized Face-Mount Joist Hanger for 4x6 is a heavy-duty structural connector from Simpson engineered for framing applications that demand additional strength and safety. Designed to accept a nominal 4x6 joist member, this face-mount hanger is the go-to choice of engineers and contractors who require a tested, load rated, and code compliant solution for both residential and commercial construction. Built from 14-gauge steel with a G90 zinc galvanized finish, it delivers the reliable performance and corrosion resistance that demanding structural connections require.

Key Features

• Heavy-duty 14-gauge steel construction - provides the structural rigidity needed for load-bearing joist connections where standard-gauge hangers fall short
• G90 zinc galvanized coating - offers corrosion resistance that helps the hanger hold up in moisture-prone environments, extending the service life of the connection
• Extra optional triangle holes - give installers the ability to add fasteners for increased load capacity when project requirements call for it
• Tested, load rated, and code compliant - takes the guesswork out of compliance, so contractors and inspectors can move forward with confidence on permitted projects
• Face-mount design for nominal 4x6 lumber - installs directly against the header face, simplifying layout and alignment during framing without the need for specialized tools
• 3-9/16 in. seat width - sized precisely for a nominal 4x6 joist, ensuring a snug, properly supported fit that maintains structural integrity

Why This Product

• Engineer- and contractor-trusted performance - Simpson Strong-Tie connectors are a proven standard on job sites where structural reliability and code compliance are non-negotiable, making the HU46 a dependable choice for professional framing work
• Built-in flexibility for higher load demands - the extra optional triangle holes allow the connection to be upgraded with additional fasteners, giving builders a single hanger that can adapt to varying load requirements without switching hardware
• Corrosion-resistant finish for long-term durability - the G90 galvanized coating makes the HU46 suitable for use in applications where moisture exposure is a concern, helping protect the structural connection over time
• Straightforward installation with clear fastener guidance - defined nail specifications for both the header and the joist mean installers spend less time guessing and more time building, keeping projects on schedule
