The Simpson 20 in. Heavy Twist Strap, Galvanized ZMAX HTS20Z from Simpson delivers a reliable tension connection between two wood members, engineered to economically resist heavy uplift loads at the rafter or heel of a truss. Fabricated from 14-gauge steel and finished with a ZMAX galvanized coating, this heavy twist strap is purpose-built for demanding exterior and treated-wood applications where long-term corrosion resistance is a priority. Its versatile design suits a wide range of structural connections, whether spanning the wide or narrow face of lumber on light repairs or heavy-duty framing projects.

Key Features

• 3-3/4 in. bend section - eliminates interference at the transition points between wood members, ensuring a clean, secure fit without reworking the connection.
• 14-gauge steel construction - provides the structural strength needed to handle heavy uplift loads at truss heels and rafter connections with confidence.
• ZMAX galvanized coating - offers extra corrosion resistance beyond standard galvanization, making this strap well suited for exterior environments and contact with treated lumber.
• Reversible bend option - HTS straps are available with the bend reversed; to order, specify "-REV" after the model number, such as HTS20Z-REV, giving installers the flexibility to match specific framing orientations.

Why This Product

• Built for treated-wood and exterior use - the ZMAX galvanized finish provides enhanced protection against corrosion in the harsh conditions common to outdoor framing and pressure-treated lumber applications, reducing long-term maintenance concerns.
• Interference-free installation - the engineered 3-3/4 in. bend section keeps the strap clear of transition points between wood members, saving installation time and reducing the risk of fit problems on the job site.
• Flexible ordering for varied framing conditions - the ability to specify a reversed-bend version means one product family can address multiple truss and rafter connection scenarios without requiring a completely different connector.
• Simple, economical uplift resistance - twist straps provide a straightforward tension connection that resists uplift at the heel of a truss economically, making this a practical choice for both structural repairs and new construction framing.

Frequently Asked Questions

What is the primary purpose of the HTS20Z heavy twist strap?

The HTS20Z provides a tension connection between two wood members and is designed to economically resist heavy uplift loads at the rafter or heel of a truss.

What type of fasteners are required to install the HTS20Z?

Install with 10d common nails or 10d x 1-1/2 in. nails. Use all specified fasteners, with half into each member being connected, to achieve the listed loads.

Can the HTS20Z be ordered with the bend in the opposite direction?

Yes. HTS are available with the bend reversed. To order, specify "-REV" after the model number, such as HTS20Z-REV.

Why is ZMAX galvanization important for this strap?

ZMAX galvanization offers extra corrosion resistance, making the HTS20Z well suited for exterior and treated-wood applications where standard galvanization may not provide sufficient protection.
