The Simpson Titen HD Threaded Rod Hanger is a high-strength screw anchor built to suspend threaded rod from concrete slabs, beams, and concrete over metal for reliable support of pipes, cable trays, and HVAC equipment. Engineered for low installation torque with no secondary setting required, this 1/4 in. x 1-5/8 in. anchor accepts 3/8 in. rod and has been tested to deliver consistent performance in both cracked and uncracked concrete - including under seismic loading conditions. Made from zinc-plated carbon steel, it is approved for dry interior applications.

Key Features

• Undercutting thread design - efficiently transfers load directly to the base material, maximizing holding strength in concrete substrates.
• Serrated cutting teeth combined with an optimized thread profile - allow the anchor to seat quickly and cleanly, reducing labor time on the job.
• Specialized heat-treating process at the tip with a ductile body - the tip is hardened for efficient cutting into concrete while the body absorbs installation stress, extending anchor reliability.
• Compatible with a rotary hammer or hammer drill and standard ANSI drill bits - no special tooling is needed, keeping installation straightforward and cost-effective.
• Code listed for cracked and uncracked concrete; FM listed - provides the documentation and third-party approval required for compliant commercial and industrial installations, including seismic applications.
• Installs with standard-sized sockets and a 1/2 in. wrench - works with common hand tools already on the job site, eliminating the need for proprietary accessories.
• Zinc-plated carbon steel construction - delivers durability in dry interior environments where corrosion exposure is minimal.

Why This Product

• Tested for seismic and cracked-concrete conditions - the Titen HD rod hanger is code listed for both cracked and uncracked concrete applications and has been evaluated under seismic loading, giving contractors confidence in demanding structural environments where anchor performance is critical.
• No secondary setting and no special tools required - the anchor installs with a rotary hammer or hammer drill using standard ANSI drill bits and a common socket, making it a practical choice for high-volume mechanical, plumbing, and HVAC suspension work.
• Engineered tip hardness with a ductile body - the specialized heat-treating process balances cutting efficiency at the tip with flexibility through the body, reducing the risk of breakage during installation and supporting consistent results across multiple anchors.
• Versatile suspension anchor for concrete structures - suitable for securing threaded rod to concrete slabs, beams, and concrete over metal, this anchor covers the most common overhead attachment scenarios in commercial construction and mechanical system installation.
