Simpson Strong Tie MSTA9 Strap Tie 9 Inches 18-gauge Steel

Product Description

The SIMPSON STRONG TIE MSTA9 is a medium strap tie used to connect and splice structural lumber members in residential and light commercial framing. Formed from 18-gauge galvanized steel, it delivers corrosion resistance suited to treated lumber and exposed framing environments. At 9 inches in length, the MSTA9 bridges two members cleanly and lies flat against the face of the lumber. The engineered nail pattern is spaced to minimize splitting risk while maximizing load transfer across the connection. Installation requires 10d common nails. This connector is a standard fastener for framing crews and structural carpenters working on wall, roof, and floor assemblies.

The MSTA9 is designed for edge installation on 2x lumber and fits a wide range of structural connection scenarios. Common applications include wall intersections, ridge ties, rafter-to-plate connections, and end-to-end lumber splices. It performs in both interior framing and exterior sheathed assemblies where a low-profile metal connector is needed. The galvanized finish makes it appropriate for use in treated-lumber applications where untreated steel connectors would corrode prematurely. Each package contains 50 pieces, making it practical to stock for production framing jobs or recurring repair work.

Key Features

• 18-gauge galvanized steel construction for corrosion resistance in treated-lumber environments
• 9-inch length sized for edge installation on standard 2x lumber
• Engineered nail pattern reduces splitting risk at connection points
• Compatible with 10d common nails for straightforward fastening

Compatibility

Designed for edge installation on 2x dimensional lumber in residential and light commercial framing applications. Use with 10d common nails as specified by the manufacturer.

Installation Notes

Installation is performed by framing carpenters or general contractors following applicable building code requirements. Position the strap flush against the lumber face and fasten using 10d common nails through the full nail pattern on both members before applying load. Do not substitute fastener type or size, as nail specification is part of the connector's load rating. Consult local building codes and the manufacturer's load tables before specifying for structural connections subject to engineer review.
