The Simpson MST48 48" 12-Gauge Galvanized Medium Strap Tie from Simpson Strong-Tie is a load-rated, precut structural strap engineered to resist tension loads in floor-to-floor connections and a wide range of structural splices. Built from 12-gauge steel with a G90 zinc galvanized finish, this medium-duty strap features a dense nailing pattern and accepts nails, bolts, or screws, making it a reliable and flexible choice for framing assemblies involving double 2x members or greater.

Key Features

• Medium-duty design for varied connections and splices - handles a broad range of structural framing applications, giving builders and contractors a single strap solution for multiple job-site scenarios
• Suitable for nominal double-2x member connections or greater - ensures proper load transfer across common framing assemblies without the need to upsize or substitute hardware
• Dense nailing pattern - distributes tension forces efficiently across the connection, supporting high-capacity load resistance where it matters most
• Multiple fastener options - installs with nails, 1/2 in. bolts, or Strong-Drive SD Connector screws, giving installers the flexibility to match fastening method to application requirements
• Precut to correct dimensions with the right number of fastener holes - eliminates field fabrication and speeds up installation while maintaining optimal structural performance
• G90 zinc galvanized coating - provides reliable corrosion resistance, making this strap suitable for structural applications where moisture exposure is a concern
• 12-gauge steel construction - delivers the strength and rigidity required for tension-load applications without adding unnecessary bulk to the connection

Why This Product

• Ready to install right out of the box - because the MST48 is precut and load-rated with the correct thickness and number of fastener holes pre-punched, there is no guesswork or field modification required, saving time and reducing installation errors
• Versatile fastening compatibility - the ability to install with nails, bolts, or Strong-Drive SD Connector screws means this strap adapts to the tools and materials already on the job site, reducing the need for specialty hardware
• Built for real structural demands - designed specifically to resist tension loads in floor-to-floor and other structural connections, the MST48 is a purpose-built solution rather than a general-purpose strap pressed into a demanding role
• Corrosion-resistant finish extends service life - the G90 zinc galvanized coating means this strap holds up over time in conditions where uncoated steel would degrade, helping protect the integrity of the structural connection long after installation
