The Simpson LUS46 LUS Series Face-Mount Joist Hanger is an economical, easy-to-install connector built for 4x6 and 4x8 nominal lumber framing applications. Designed to provide support underneath the joist, rafter, or beam, this hanger uses a patented double-shear nailing design that distributes load through two points on each joist nail - delivering greater connection strength while requiring fewer nails and allowing the use of all common nails for the same connection. Formed from 18-gauge steel with a G90 zinc galvanized finish, it is a widely trusted choice for residential and light commercial face-mount framing work.

Key Features

• Patented double-shear nailing design - distributes load through two points on each joist nail, so you get greater strength with fewer nails and faster installation compared to single-shear alternatives
• Speed prongs - hold the hanger in position hands-free during installation, reducing layout time and the chance of misalignment
• Angled joist nailing - makes driving fasteners easier when working in tight spaces where a straight approach is not practical
• Compatible with 4x6 and 4x8 nominal lumber - fits a wide range of common joist, rafter, and beam sizes so one hanger model covers multiple framing scenarios
• 18-gauge steel construction - provides a solid, rigid connector that maintains its shape and holding capacity under load
• G90 zinc galvanized finish - delivers extra corrosion resistance for longer service life in exposed or moisture-prone framing environments
• Do not bend or remove tabs - tabs are integral to the structural performance of the hanger and must remain intact to achieve rated loads

Why This Product

• Fewer nails, same strong connection - the patented double-shear design means each nail works harder, so you drive fewer fasteners without sacrificing rated load capacity, cutting both material use and installation time on the job
• Built for practical field conditions - speed prongs and angled joist nailing work together to make installation faster and more manageable even in confined framing bays or overhead applications
• Corrosion resistance you can count on - the G90 zinc galvanized coating provides a meaningful layer of protection against moisture and oxidation, making this hanger suitable for applications where bare steel would degrade prematurely
• Trusted Simpson engineering for standard framing - the LUS series is a widely used, proven face-mount hanger designed for common lumber sizes, giving builders and contractors a reliable, code-friendly connector for everyday joist, rafter, and beam connections

Frequently Asked Questions

What fasteners should be used to install the Simpson LUS46?

Install with Simpson Strong-Tie Strong-Drive SD Connector screws: (4) #9 x 1-1/2 in. screws in the header AND (4) #9 x 2-1/2 in. screws in the joist, OR (8) 0.162 in. x 3-1/2 in. Strong-Drive SCN Smooth-Shank Connector nails (Models: SD9112, SD9212, 16DHDG). Always use all specified fasteners to achieve rated table loads.

What is the double-shear nailing design and why does it matter?

The patented double-shear nailing design distributes the load through two points on each joist nail, resulting in greater connection strength. This means fewer nails are needed compared to single-shear designs, which also speeds up installation while maintaining a strong, reliable connection.

What lumber sizes is the LUS46 compatible with?

The LUS46 is designed for nominal 4x6 and 4x8 lumber member sizes, making it suitable for a wide range of common framing applications involving joists, rafters, or beams of those dimensions.

Can the tabs on the LUS46 be bent or removed to fit a specific application?

No. The tabs on the LUS46 must not be bent or removed. Modifying the connector in this way can compromise its structural integrity and load-rated performance. The hanger should be installed as designed to maintain compliance with tested load values and applicable codes.
