The Simpson MSTA15Z Medium Strap Tie from Simpson is a reliable, medium-duty connector built to join and reinforce a wide range of wood-to-wood connections and splices. Constructed from 18-gauge steel with a ZMAX galvanized finish, this strap tie is engineered for use on the edge of 2x members and is well-suited for exterior framing and treated-wood assemblies where corrosion resistance is a priority. Whether you are tying ridges, reinforcing wall intersections, or bridging cut plates and soles, this strap delivers straightforward, versatile performance on the job.

Key Features

• Medium-duty, versatile strap design - handles a broad range of connections and splices so one connector works across multiple framing situations
• Engineered for installation on the edge of 2x members - puts the strap exactly where it is needed for secure wood-to-wood connections without repositioning
• Nailing pattern designed to reduce splitting potential - protects the integrity of your lumber during fastening, helping maintain structural reliability at the connection point
• Installs where plates or soles are cut, at wall intersections, and as ridge ties - covers the most common framing repair and reinforcement scenarios with a single product
• ZMAX galvanization provides extra corrosion resistance - makes this strap tie a confident choice for exterior applications and assemblies involving treated lumber where standard coatings may fall short
• Compatible with 10d common nails - works with a widely available, standard fastener so installation stays simple and cost-effective

Why This Product

• One strap, many applications - the MSTA15Z is designed to work at wall intersections, ridge ties, and cut-plate locations, reducing the need to stock multiple connector types for common framing tasks
• Built for treated-wood and exterior conditions - ZMAX galvanization goes beyond standard coatings to deliver the added corrosion resistance demanded by pressure-treated lumber and outdoor framing environments
• Lumber-friendly nailing pattern - the thoughtfully spaced fastener layout minimizes splitting risk along the edge of 2x members, protecting both the connector's holding power and the surrounding wood
• American-made quality from a trusted structural connector brand - backed by Simpson's engineering standards, giving contractors and builders confidence in the connector's consistency and performance on every project
