Product Description
The Simpson MST72 Medium Strap Tie is a load-rated, precut structural strap from Simpson Strong-Tie, engineered to resist tension loads in floor-to-floor connections and a wide range of other structural applications. Fabricated from 10-gauge steel with a dense nailing pattern, this high-capacity strap is sized and pre-punched for quick installation and optimal performance when connecting double or greater 2x members. Whether you are tying floor systems together, splicing structural lumber, or reinforcing against wind and seismic forces, this galvanized medium strap delivers reliable, code-friendly performance across job types.
Key Features
- Versatile medium-duty design - suits a broad range of structural connections and splices, reducing the need to stock multiple strap types on the job site
- Sized for 3-1/2 in. or larger wood members - ensures proper load transfer and minimizes splitting risk when used with the correct member size
- Multiple fastener options (nails, bolts, or Strong-Drive SD Connector screws) - gives installers flexibility to work with the tools and fasteners already on hand
- Load-rated and precut - ships with the correct thickness and number of fastener holes already in place, so there is no field cutting or guesswork, saving installation time
- 10-gauge steel construction - provides the high-capacity strength needed for demanding floor-to-floor and other structural tension applications
- Zinc Galvanized G90 coating - delivers corrosion resistance suitable for structural framing environments, helping protect the connection over the life of the building
Why This Product
- Engineered for efficiency - the precut, pre-punched format means the strap arrives ready to install with the optimal number of fastener holes already positioned, cutting layout time and reducing installation errors on the job site
- High-capacity tension resistance in a single strap - designed specifically to resist tension loads in floor-to-floor and other demanding applications, this medium-duty strap handles structural splices and connections that standard light-gauge straps cannot
- Fastener flexibility without compromising performance - acceptance of nails, bolts, or Strong-Drive SD Connector screws means crews can adapt to site conditions and available fasteners while still achieving full load-rated performance
- Made in the United States by a trusted structural connector brand - Simpson Strong-Tie produces this strap domestically to consistent quality standards, giving contractors and engineers confidence in the product they are specifying and installing
