The Simpson MST48HDG 48" 12-Gauge Hot-Dip 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 framing splices. Built from 12-gauge steel with a hot-dip galvanized finish, this medium-duty strap supports double 2x member connections or greater and accommodates nails, bolts, or screws for straightforward installation across both interior framing and demanding exterior or treated-wood applications.

Key Features

• Versatile medium-duty design for connections and splices - handles a broad range of structural framing tasks without requiring multiple specialty straps
• Suitable for nominal double-2x member connections or greater - gives builders confidence the strap is appropriately sized for common multi-member framing assemblies
• 12-gauge steel construction - delivers the thickness and rigidity needed for reliable tension load resistance in structural applications
• Hot-dip galvanized coating - provides extra corrosion resistance beyond standard finishes, making this strap a dependable choice for exterior jobsites and pressure-treated lumber installations
• Load-rated and precut with the correct number of fastener holes - eliminates guesswork on the installation site and supports optimal, code-consistent performance out of the box
• Compatible with nails, bolts, or Strong-Drive SD Connector screws - lets installers use the fastener type that best suits the application, reducing the need for specialty hardware

Why This Product

• Ready to install without modification - because the MST48HDG is precut and pre-punched with the correct thickness and fastener hole count, contractors can move quickly through floor-to-floor and splice connections without cutting or drilling on site
• Built for tough exposure conditions - the hot-dip galvanized finish goes beyond standard coatings to protect against corrosion in exterior framing environments and wherever treated wood is used, helping the connection maintain its integrity over time
• Multi-fastener flexibility on a single strap - the ability to install with nails, 1/2 in. bolts, or Strong-Drive SD Connector screws means this strap adapts to the tools and methods already on the job rather than dictating a specific approach
• A single medium-duty strap that spans a wide range of applications - from floor-to-floor tension loads to general structural splices on double 2x or larger members, this strap reduces the number of different connectors a crew needs to stock and source

Frequently Asked Questions

What size members is the Simpson MST48HDG designed to connect?

The MST48HDG is suitable for nominal double-2x member connections or greater, making it appropriate for a range of medium-duty structural framing applications.

What fasteners can be used to install the MST48HDG?

The MST48HDG can be installed with (50) 0.162 in. x 2-1/2 in. nails, (8) 1/2 in. bolts, or (50) #10 x 1-1/2 in. Strong-Drive SD Connector screws, offering flexibility to suit different installation requirements.

Why is the MST48HDG hot-dip galvanized instead of standard galvanized?

Hot-dip galvanization (HDG) provides an extra layer of corrosion resistance compared to standard coatings, making the MST48HDG well-suited for exterior applications and installations involving treated wood where greater durability is needed.

Is the MST48HDG a precut, load-rated strap?

Yes. The MST48HDG is a load-rated, precut strap with the correct thickness and number of fastener holes already in place, allowing for quick installation and ensuring optimal structural performance without requiring field modification.
