The Simpson MSTA12SS 12" Medium Strap Tie Stainless Steel 18-Gauge from Simpson is engineered to resist tension loads in wood-to-wood uplift applications, making it a dependable choice for structural connections where holding power matters. Built from 18-gauge stainless steel and designed for use on the edge of 2x members, this medium strap tie features a staggered nail pattern that helps minimize wood splitting during installation - preserving the integrity of the members being connected. Its stainless-steel construction delivers high/severe corrosion resistance, making it well suited for demanding environments where standard steel hardware would deteriorate over time.

Key Features

• Load-rated thickness and fastener count - ensures consistent, verified structural performance unlike field-fabricated straps that lack standardized ratings
• Increased load values for wind and seismic forces - gives builders and contractors confidence in applications where uplift resistance to dynamic forces is required
• Floor-to-floor clear span application - supports continuous load transfer across floor levels without interruption, simplifying multi-story framing connections
• Designed for use on the edge of 2x members - fits precisely where it is needed in common framing assemblies, reducing guesswork during installation
• Staggered nail pattern - helps minimize wood splitting so the structural integrity of the connected members is maintained through the fastening process
• 18-gauge stainless-steel construction - provides high/severe corrosion resistance for long-term durability in harsh or moisture-exposed environments
• Install with stainless-steel 10d common nails - maintaining consistent material compatibility throughout the connection protects corrosion resistance integrity across the entire assembly

Why This Product

• Engineered reliability over field-built alternatives - unlike field-fabricated straps, this strap tie is load rated with the correct thickness and number of fasteners, removing the guesswork and inconsistency that come with on-site improvisation
• Built for high-stakes structural environments - with load values increased for wind and seismic forces, this medium strap tie is designed to perform in applications where uplift resistance is critical to the safety of the structure
• Stainless-steel construction for long-term durability - the stainless-steel finish delivers high/severe corrosion resistance, making this strap tie a sound investment for coastal, high-humidity, or other corrosive environments where standard hardware fails prematurely
• Installation-friendly design that protects the wood - the staggered nail pattern helps minimize wood splitting during fastening, preserving the strength of the 2x members and reducing the risk of installation damage on the job site

Frequently Asked Questions

What fasteners should be used to install the MSTA12SS?

Install with stainless-steel 10d common nails to ensure compatibility with the stainless-steel strap and maintain corrosion resistance integrity.

Why choose the MSTA12SS over a field-fabricated strap?

Unlike field-fabricated straps, the MSTA12SS is load rated with the correct thickness and number of fasteners, ensuring consistent, reliable performance in structural applications.

Is the MSTA12SS suitable for use in corrosive environments?

Yes. The MSTA12SS is made from stainless steel, providing high/severe corrosion resistance, making it well suited for environments where standard steel hardware would be prone to corrosion.

What is the staggered nail pattern on the MSTA12SS designed to do?

The staggered nail pattern is designed to help minimize wood splitting during installation, which helps preserve the structural integrity of the 2x members being connected.
