Product Description
The Simpson U310 Face-Mount Joist Hanger is a precision-formed, 16-gauge steel connector engineered for joist-to-header installation in wood-framed construction. Manufactured by Simpson, this face-mount hanger delivers dependable structural performance for floor and roof framing applications where tested strength, straightforward installation, and code compliance are non-negotiable.
Key Features
- Tested, load rated, and code compliant - gives builders and inspectors confidence that the hanger meets recognized structural standards right out of the box.
- Compatible with several fastener selections, each with tested allowable loads - provides installation flexibility so crews can work with the nail sizes they have on hand without sacrificing verified performance.
- Fits nominal 3x10 and 3x12 joist members - covers two common framing dimensions in a single hanger model, reducing the number of SKUs needed on the job site.
- Formed from 16-gauge steel - delivers the structural rigidity required for demanding load-bearing framing connections in residential and light commercial construction.
- G90 zinc galvanized finish - provides extra corrosion resistance, making the hanger suitable for applications where moisture exposure is a concern.
Why This Product
- Engineered for real-world framing conditions - the U-series design is purpose-built for joist-to-header connections, so it fits naturally into standard wood-frame construction workflows without modification or guesswork.
- Dual-size compatibility reduces job site complexity - a single U310 hanger supports both 3x10 and 3x12 nominal lumber, giving framing crews a versatile connector that adapts to changing layout requirements.
- G90 galvanized coating goes beyond basic protection - the extra corrosion resistance extends the service life of the connection in crawl spaces, covered decks, and other environments where bare steel would degrade over time.
- Precision-formed construction from a trusted brand - Simpson manufactures the U310 to high quality standards, and its tested, load-rated performance means structural calculations and code submissions are backed by documented data.
