The Simpson MSTA49 Medium Strap Tie is engineered by Simpson to resist tension loads in wood-to-wood uplift applications, delivering dependable structural performance where floor-to-floor clear span connections demand consistent, code-compliant results. Built from 16-gauge steel with a G90 zinc galvanized finish, this medium strap tie features a staggered nail pattern to help minimize wood splitting during installation, and is designed specifically for use on the edge of 2x members - making it a reliable choice for uplift resistance in both wind and seismic force applications.

Key Features

• Load-rated construction with correct thickness and fastener count - eliminates the guesswork and inconsistency of field-fabricated straps, giving you confidence that every connection meets rated performance requirements
• Increased load values for wind and seismic forces - provides enhanced structural reliability in demanding conditions where uplift resistance is critical
• Floor-to-floor clear span application - designed to bridge the gap between floor levels without interruption, simplifying multi-story framing connections
• Designed for use on the edge of 2x members - ensures proper fit and alignment for standard framing lumber, reducing installation error
• Staggered nail pattern - strategically spaced fastener holes help minimize wood splitting, preserving the structural integrity of connected members
• 16-gauge steel construction - delivers the strength and rigidity needed for load-rated uplift strap applications in residential and light commercial framing
• G90 zinc galvanized finish - provides extra corrosion resistance, extending service life in moisture-prone environments and helping protect the connection over time

Why This Product

• Engineered performance you can count on - unlike field-fabricated alternatives, this strap tie is load rated with the correct thickness and number of fasteners, so every installation delivers consistent, verifiable uplift resistance without the variability of job-site fabrication
• Built for high-stress structural demands - with load values increased for wind and seismic forces, this strap tie is purpose-built for applications where connections must perform under the most challenging lateral and uplift conditions
• Corrosion-resistant for long-term durability - the G90 zinc galvanized finish adds a meaningful layer of protection against moisture and corrosion, making this strap tie a sound investment for connections that need to last
• Installation-friendly design that protects your materials - the staggered nail pattern reduces the risk of splitting 2x lumber during fastening, helping you complete floor-to-floor strap connections cleanly and efficiently without compromising the wood members

Frequently Asked Questions

What type of fasteners should be used to install the MSTA49?

The MSTA49 should be installed with 10d common nails or #9 x 1-1/2 in. Strong-Drive SD screws for proper load-rated performance.

Why is the MSTA49 preferred over a field-fabricated strap?

Unlike field-fabricated straps, the MSTA49 is load rated with the correct thickness and number of fasteners, ensuring consistent, code-compliant performance in uplift applications.

What is the purpose of the staggered nail pattern on the MSTA49?

The staggered nail pattern is specifically designed to help minimize wood splitting during installation, which helps maintain the structural integrity of the connected members.

What corrosion protection does the MSTA49 offer?

The MSTA49 is coated with a G90 zinc galvanized finish, which provides extra corrosion resistance, making it suitable for use in environments where moisture exposure is a concern.
