Simpson 12 in. x 12 in. 7-Gauge Hot-Dip Galvanized Heavy T Strap by Simpson is a heavy-duty structural connector engineered to join and reinforce right-angle intersections where one member meets another at 90 deg. Built from thick 7-gauge steel with a hot-dip galvanized finish, this T strap is designed for demanding exterior and treated-wood applications where connection integrity and long-term corrosion resistance are non-negotiable. Whether used in timber framing, structural repairs, or heavy-duty joinery projects, this strap delivers the reliable load transfer that critical connections require.

Key Features

• 90 deg. T-intersection reinforcement - creates a strong, stable connection exactly where one structural member crosses or meets another, keeping joints secure under load
• Strongest when used in pairs - installing two straps back-to-back maximizes load transfer and overall connection strength, giving builders confidence on high-demand joints
• 2-1/2 in. strap width - provides a broad bearing surface across the lumber face for better force distribution and a more secure mechanical connection
• 12 in. x 12 in. dimensions - generous height and length deliver ample fastening area on both intersecting members, reducing stress concentration at the joint
• 7-gauge steel construction - the heavy material thickness resists bending and deformation, making this strap well suited for structural and load-bearing applications
• Hot-dip galvanized finish - the HDG coating offers extra corrosion resistance compared to standard finishes, protecting the connector against moisture and the chemicals present in treated lumber over the long term
• Installs with 5/8 in. diameter bolts - compatibility with standard bolt sizing simplifies procurement and ensures a properly loaded, code-conscious connection

Why This Product

• Built for harsh conditions - hot-dip galvanization provides a level of corrosion protection that makes this strap a dependable choice for exterior structures, ground-contact assemblies, and projects involving pressure-treated lumber where moisture and chemical exposure can degrade lesser connectors over time
• Heavy-gauge strength where it counts - 7-gauge steel construction means this T strap handles the rigors of structural joinery without sacrificing material integrity, giving contractors and builders a connector they can rely on for load-bearing connections
• Versatile pairing capability - designed to perform strongest when installed in pairs, this strap gives builders a straightforward way to scale connection strength to match project demands without requiring specialty hardware
• Trusted Simpson engineering - backed by Simpson's long-standing focus on structural connector solutions, this strap reflects the same design philosophy of simple, versatile, field-proven performance that spans a wide range of framing and reinforcement applications

Frequently Asked Questions

What is the primary purpose of the Simpson 1212HTHDG Heavy T Strap?

The 1212HTHDG is a reinforcement T strap designed to create a strong connection where one structural member intersects another at a 90 deg. angle, making it ideal for joining and reinforcing right-angle joints in a wide range of construction and structural applications.

What size bolts should be used to install the 1212HTHDG?

This heavy T strap is designed to be installed with 5/8 in. diameter bolts for a secure and properly loaded connection.

Why is the hot-dip galvanized finish important for this strap?

Hot-dip galvanization (HDG) provides extra corrosion resistance compared to standard finishes, making the 1212HTHDG suitable for exterior applications and use with treated lumber where exposure to moisture and chemicals could otherwise degrade an uncoated or lightly coated strap.

Should the 1212HTHDG be used alone or in pairs?

While the strap can be used individually, it is strongest when used in pairs. Installing two straps back-to-back on a structural member maximizes load transfer and connection strength at the 90 deg. intersection point.
