The Simpson MSTA24Z MSTA 24-in. 18-Gauge ZMAX Galvanized Medium Strap Tie from Simpson is engineered to resist tension loads in wood-to-wood uplift applications, delivering dependable structural performance where it matters most. Designed specifically for use on the edge of 2x members, this medium strap tie incorporates a staggered nail pattern to help minimize wood splitting during installation. ZMAX galvanization provides extra corrosion resistance, making this strap tie a strong choice for exterior environments and treated-wood applications where long-term durability is essential.

Key Features

• Load-rated with correct thickness and number of fasteners - eliminates the guesswork of field-fabricated straps, giving you predictable, tested performance on every installation
• Increased load capacity for wind and seismic forces - engineered to meet demanding structural requirements, making this strap tie suitable for high-stress uplift and tension connections
• Floor-to-floor clear span application - purpose-built geometry supports reliable connections across full-span installations without compromising structural integrity
• Designed for use on the edge of 2x members - ensures proper fit and alignment in standard framing assemblies, reducing the risk of improper placement
• Staggered nail pattern - helps minimize wood splitting during fastener installation, preserving the strength and integrity of the connected members
• ZMAX galvanization - provides extra corrosion resistance for exterior and treated-wood applications where standard coatings may fall short over time
• 18-gauge steel construction, 24 in. long and 1-1/4 in. wide - offers a sturdy, consistent profile that holds its shape under load and simplifies positioning during installation

Why This Product

• Tested performance you can rely on - unlike field-fabricated alternatives, this strap tie is load rated with the correct thickness and fastener count, so structural connections meet verified load requirements for wind and seismic forces rather than relying on estimation
• Built for harsh and treated-wood environments - the ZMAX coating delivers extra corrosion resistance beyond standard galvanization, making this tie a durable choice for exterior framing and pressure-treated lumber applications where moisture and chemical exposure are ongoing concerns
• Installer-friendly design that protects the wood - the staggered nail pattern actively reduces the risk of wood splitting, helping preserve the integrity of 2x members and keeping the installation clean and structurally sound from the start
• Versatile for common structural connection needs - suited for wood-to-wood uplift resistance and floor-to-floor clear span connections, this medium strap tie covers a broad range of residential and light-commercial framing applications in one straightforward component

Frequently Asked Questions

What type of fasteners should be used to install the MSTA24Z?

The MSTA24Z 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 ZMAX coating important for this strap tie?

ZMAX galvanization offers extra corrosion resistance, making the MSTA24Z suitable for exterior and treated-wood applications where standard galvanization may not provide adequate protection.

How does the staggered nail pattern benefit the installation?

The staggered nail pattern is designed to help minimize wood splitting during installation, preserving the integrity of the wood members and ensuring a secure connection.

What makes load-rated straps better than field-fabricated straps?

Unlike field-fabricated straps, the MSTA24Z is load rated with the correct thickness and number of fasteners, providing predictable, tested performance for wind and seismic force resistance.
