The Simpson LUS48 LUS Series Face-Mount Joist Hanger is an economical, easy-to-install structural connector built for solid sawn lumber framing projects that call for 4x8 or 4x10 members. Constructed from 18-gauge steel with a G90 galvanized finish for lasting corrosion resistance, this hanger is engineered to deliver a strong, reliable connection beneath joists, rafters, or beams in common lumber framing applications. Its patented double-shear nailing design distributes the load through two points on each joist nail, allowing contractors and builders to achieve greater connection strength while using fewer nails and completing installations faster.

Key Features

• Patented double-shear nailing design - distributes load through two points on each joist nail, giving you a stronger connection with fewer nails and faster installation using all common nails
• Speed prongs - hold the hanger in position during installation so you can work quickly without a helper to hold hardware in place
• Angled joist nailing - lets you drive nails at an angle through the joist into the header, making fastening easier even in tight or confined framing spaces
• 18-gauge steel construction - provides the structural rigidity needed for dependable load support in face-mount joist and rafter applications
• G90 galvanized coating - offers corrosion resistance suitable for treated lumber and outdoor framing environments where bare steel would degrade over time
• Compatible with 4x8 and 4x10 nominal lumber - covers two common framing member sizes in a single hanger, reducing the number of different part numbers you need to stock on the job
• Tabs must not be bent or removed - preserving the factory geometry maintains the structural integrity of the connection and keeps the installation code-compliant

Why This Product

• Fewer nails, faster installs, no loss of strength - the patented double-shear nailing design is the core advantage here: each joist nail works at two load points simultaneously, so you drive fewer fasteners while meeting the same connection requirements, cutting labor time on repetitive framing tasks
• Built-in features that speed up field work - speed prongs and angled joist nailing work together to make single-person installation practical even in cramped bays or multi-joist runs where access is limited
• Versatility across two member sizes - dual compatibility with 4x8 and 4x10 nominal lumber means one hanger model handles a range of common framing scenarios, simplifying procurement and reducing on-site inventory
• G90 galvanized protection from a trusted structural hardware brand - Simpson engineering and a G90 galvanized finish combine to deliver a hanger that holds up in moisture-exposed and treated-lumber applications without sacrificing the load performance the connection demands

Frequently Asked Questions

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 rather than one. This results in greater connection strength while requiring fewer nails, speeding up installation and allowing the use of all common nails for the same connection.

What lumber sizes is the LUS48 compatible with?

The LUS48 is designed for a nominal joist size of 4x8 and 4x10 lumber, with a hanger seat width of 3-9/16 in. to accommodate these common dimensional lumber sizes.

What fasteners should be used to install the LUS48?

Install with Simpson Strong-Tie Strong-Drive SD Connector screws: (6) #9 x 1-1/2 in. screws in the header AND (4) #9 x 2-1/2 in. screws in the joist, OR (10) 0.162 in. x 3-1/2 in. Strong-Drive SCN Smooth-Shank Connector nails (Models: SD9112, SD9212, 16DHDG).

Is the LUS48 suitable for outdoor or treated-lumber applications?

Yes. The LUS48 is coated with a G90 galvanized zinc finish, which provides corrosion resistance making it appropriate for applications where exposure to moisture or treated lumber is a concern.
