The Simpson 66T 6 in. x 5 in. 14-Gauge Galvanized T Strap is a heavy-duty reinforcement connector built to create strong, reliable joints where one structural member intersects another at a 90 deg. angle. Manufactured by Simpson from 14-gauge steel with a G90 zinc galvanized coating, this T strap delivers the corrosion resistance and structural integrity needed for everything from light lumber repairs to demanding load-bearing applications. Its straightforward, versatile design makes it a practical choice for beam-to-post connections, framing reinforcement, and a wide range of perpendicular joint applications on the wide or narrow face of lumber.

Key Features

• T-strap design for 90 deg. intersecting members - provides targeted reinforcement exactly where one structural member meets another perpendicularly, keeping joints secure under load
• Strongest when used in pairs - installing two straps opposite each other maximizes holding strength, giving builders a simple way to upgrade connection performance on critical joints
• 14-gauge steel construction - delivers the thickness and rigidity required for both light repair work and heavy-duty structural projects without adding unnecessary bulk
• G90 zinc galvanized coating - provides extra corrosion resistance, making this strap a dependable choice in moisture-prone environments where untreated metal would degrade over time
• Compatible with nails or bolts - installs with either (8) 0.162 in. x 2-1/2 in. nails or (3) 3/8-in. diameter bolts, giving contractors flexibility to match the fastener type to the demands of the job

Why This Product

• Versatile across a wide range of connections - this T strap works on the wide or narrow face of lumber and suits applications from minor framing repairs to heavy structural reinforcement, reducing the need for multiple specialty connectors on a single job site
• Built-in corrosion protection you can count on - the G90 galvanized finish means the strap holds up in damp or humid conditions without the early rust and degradation that can compromise an untreated connector over time
• Two fastener options for real-world flexibility - nail or bolt installation means this strap adapts to your workflow and structural requirements rather than locking you into a single method
• American-made quality from a trusted connector brand - Simpson Strong-Tie straps and plates are engineered to join and reinforce joints with simple, proven solutions, and the 66T carries that same standard of reliability into a compact, easy-to-install utility strap
