The Simpson MSTCM60 59-1/2 in. 16-Gauge Galvanized Medium Strap Tie is a purpose-built wood-to-masonry connector from Simpson Strong-Tie, engineered to join and reinforce structural connections between wood framing and grouted concrete block. Spanning nearly five feet, this versatile strap tie is designed for demanding uplift applications - including floor-to-floor clear span framing - where a secure, load-bearing bond between lumber and masonry is critical. Its simple, precut form makes it a practical solution for both light structural repairs and heavy-duty framing projects where reliable performance is non-negotiable.

Key Features

• Countersunk nail slots for a lower nailing profile - keeps fastener heads flush and below the strap surface, reducing interference with adjacent materials and delivering a cleaner finished installation.
• Attaches to grouted concrete block and wood framing - purpose-built for wood-to-masonry connections, making it a direct fit for concrete masonry unit applications without additional modification.
• 3 in. width with 59-1/2 in. length - the generous length spans across floor-to-floor and structural framing connections, while the 3 in. width distributes load effectively across the strap.
• Made from 16-gauge steel - provides the structural rigidity needed to resist tension loads in uplift and lateral force applications without adding unnecessary bulk.
• G90 zinc galvanized coating - delivers extra corrosion resistance, helping the strap hold up in moisture-exposed framing environments over the long term.
• Minimum 1 1/2 in. end and edge distance for Titen screws - clearly defined fastener placement requirements take the guesswork out of installation and help ensure code-compliant results.
• Compatible with 16d sinkers and Titen 2 screws - works with widely available, standard fasteners, so installers are not locked into hard-to-source specialty hardware.

Why This Product

• Engineered specifically for wood-to-masonry uplift connections - unlike general-purpose straps, the MSTCM series is designed around the unique demands of attaching wood framing directly to concrete or grout-filled concrete masonry units, making it the right tool for seismic and wind-resistance applications.
• Long strap length handles complex structural spans - at 59-1/2 in., this strap accommodates floor-to-floor clear span connections that shorter ties simply cannot reach, reducing the need for stacked or spliced solutions.
• Countersunk slots simplify installation and reduce profile - the lower nailing profile means faster, cleaner fastening against framing surfaces, helping crews work more efficiently without sacrificing connection integrity.
• G90 galvanized finish supports use in demanding environments - the extra corrosion protection built into the coating extends the service life of the connector in installations where moisture exposure is a real-world concern.

Frequently Asked Questions

What type of fasteners are required to install the MSTCM60?

Install with 16d sinkers and (a) 1-1/4 in. x 2 in. Titen 2 screws for GFCMU or (b) 1-1/4 in. x 1-3/4 in. Titen 2 screws for Concrete.

What is the minimum end and edge distance required for Titen screws?

The minimum end and edge distance for Titen screws is 1-1/2 in.

What corrosion protection does the MSTCM60 offer?

The MSTCM60 features a G90 zinc galvanized coating, which provides extra corrosion resistance suitable for demanding installation environments.

What is the purpose of the countersunk nail slots on the MSTCM60?

The countersunk nail slots on the MSTC series are designed to create a lower nailing profile, allowing for a cleaner and more flush installation against framing and masonry surfaces.
