The Simpson Titen HD 3/8 in. x 6-3/4 in. Rod Coupler is a screw anchor engineered for single and multi-story rod tiedown systems, offering a fast, reliable method to connect threaded rod to a concrete stem wall or thickened slab footing. Built from carbon steel with a zinc-plated finish for dry interior use, this anchor eliminates the delays associated with adhesive anchors - no cure time, no secondary setting process, and no specialized equipment required. Simply drill a hole and drive the anchor to complete a secure, structurally sound connection.

Key Features

• Code listed in ESR-2713 for wind and seismic loading - gives contractors and engineers documented assurance that this anchor meets recognized code requirements for structural tiedown applications in demanding loading conditions.
• Serrated cutting teeth and patented thread design - enable fast, straightforward installation so crews spend less time per anchor and more time moving the job forward.
• Specialized heat-treating process creates tip hardness while the body remains ductile - balances cutting performance at the tip with the toughness needed throughout the body for a reliable, long-lasting connection.
• No special setting tools required - installs with a regular or hammer drill, ANSI size bits, and standard sockets, so crews can use common jobsite equipment without sourcing additional gear.
• Less installation time translates to lower installed cost - the streamlined drive-in process reduces labor hours compared to adhesive anchor systems, supporting tighter project budgets.
• Zinc-plated carbon steel construction - provides a finished, corrosion-resistant surface appropriate for dry interior environments where the anchor will perform as designed.

Why This Product

• Eliminates adhesive anchor delays - because no cure time or secondary setting process is needed, tiedown rod installation can proceed immediately after driving, keeping multi-story framing schedules on track.
• Verified for wind and seismic applications - the ESR-2713 code listing provides the documentation engineers and inspectors need to approve this screw anchor on projects with wind and seismic load requirements.
• Compatible with standard jobsite tools - working with a regular or hammer drill, ANSI size bits, and standard sockets means no investment in proprietary equipment and no learning curve for experienced crews.
• Purpose-built tip-to-body engineering - the heat-treating process that hardens the cutting tip while keeping the body ductile is a deliberate design choice that supports both ease of installation and structural integrity in concrete stem wall and slab footing connections.

Frequently Asked Questions

What type of drill and bits are needed to install the Titen HD Rod Coupler?

No special setting tools are required. The Titen HD rod coupler installs with a regular or hammer drill, ANSI size bits, and standard sockets, making it compatible with common jobsite equipment.

Is this anchor approved for wind and seismic loading applications?

Yes. The Titen HD Rod Coupler is code listed in ESR-2713 for both wind and seismic loading, making it suitable for structural tiedown applications in these demanding conditions.

Can this anchor be used in wet or exterior environments?

No. The zinc-plated carbon steel construction is intended for use in dry interior environments only and is not rated for wet, exterior, or corrosive exposure conditions.

How does the Titen HD Rod Coupler differ from adhesive anchors?

Unlike adhesive anchors, the Titen HD Rod Coupler requires no cure time, no secondary setting process, and no special tools. The serrated cutting teeth and patented thread design allow for immediate installation - simply drill a hole and drive the anchor.
