Product Description
The Simpson MSTAM36 36-Inch 16-Gauge Galvanized Medium Masonry Strap Tie is an engineered structural connector built by Simpson to resist tension loads in wood-to-masonry uplift applications. Fabricated from 16-gauge steel with a G90 zinc galvanized finish, this medium strap tie works with both concrete and grout-filled concrete masonry units (GFCMU), making it a reliable choice for floor-to-floor clear span connections and assemblies subject to wind and seismic forces. A staggered nail pattern is incorporated into the design to help minimize wood splitting during installation.
Key Features
- Load-rated with correct thickness and fastener count - delivers engineered, verifiable performance that field-fabricated straps cannot match, giving installers confidence in every connection
- Increased load ratings for wind and seismic forces - means the strap meets the demands of structural assemblies in high-stress environments without requiring supplemental hardware
- Floor-to-floor clear span application - allows the strap to bridge between framing levels cleanly, reducing the need for additional blocking or intermediate connectors
- Staggered nail pattern - minimizes wood splitting during fastener installation, preserving the structural integrity of the wood framing member
- 16-gauge steel construction - provides the rigidity and load capacity required for tension and uplift resistance in masonry-to-wood connections
- G90 zinc galvanized finish - protects against corrosion in demanding construction environments, helping the connector maintain its structural integrity over the life of the assembly
Why This Product
- Engineered reliability over field fabrication - unlike a strap cut and bent on the job site, this connector is load rated with the precise thickness and fastener count needed for the application, removing guesswork and reducing liability for contractors and builders
- Dual-substrate compatibility - rated for use with both concrete and grout-filled concrete masonry units, this masonry strap tie adapts to the substrate on site without requiring a different product for each condition
- Built for wind and seismic demand - load ratings have been increased for wind and seismic forces, making this strap tie well suited for structural framing projects in areas with elevated lateral and uplift load requirements
- Corrosion-resistant from day one - the G90 zinc galvanized coating is applied at the manufacturing stage, so the strap arrives on the job site ready to perform in exterior and exposed construction conditions without additional treatment

Frequently Asked Questions
- What fasteners are required to install the MSTAM36?
- Install with (13) 0.148 in. x 3 in. common nails AND (8) 1-1/4 in. x 2-1/4 in. Titen Turbo screws for GFCMU, OR (8) 1-1/4 in. x 1-3/4 in. Titen Turbo screws for concrete.
- What masonry substrates is the MSTAM36 compatible with?
- The MSTAM36 is designed for use with either concrete or grout-filled concrete masonry units (GFCMU).
- Why is the MSTAM36 preferred over a field-fabricated strap?
- Unlike field-fabricated straps, the MSTAM36 is load rated with the correct thickness and number of fasteners, ensuring reliable, engineered performance for tension and uplift loads in structural applications.
- What does the G90 galvanized coating provide?
- The G90 zinc galvanized coating provides corrosion resistance, helping the strap maintain its structural integrity in demanding construction environments.
