The Simpson RSH37100N Horizontal Steel Rod Hanger is a one-piece, self-drilling threaded anchor engineered by Simpson for suspending 3/8 in. threaded rod in horizontal installations. Designed specifically for installation into the side of steel joists, columns, and overhead structural members, this carbon steel anchor delivers a fast, reliable attachment point without the need for predrilling. It is well suited for pipe hanging, fire protection systems, electrical conduit support, and cable-tray applications in dry, interior, non-corrosive environments.

Key Features

• Self-drilling design, no predrilling required - drives directly into steel members, reducing installation steps and saving time on the job.
• Horizontal installation orientation - engineered specifically for side-of-member installations into joists, columns, and overhead members, giving installers a secure mounting option where vertical hangers are not practical.
• Compatible with 3/8 in. - 16 threaded rod - accepts standard 3/8 in. rod at 16 threads per inch, ensuring a consistent, secure thread engagement for supported systems.
• Anchor size: 1/4 in. x 1 in. - compact form factor fits tight framing conditions while still providing a solid anchor in compatible steel member gauges.
• Custom-matched nut driver (model RND62, sold separately) sets anchor to optimal depth - promotes consistent, repeatable installation results and reduces the risk of under- or over-driving the anchor.
• Nut included - arrives ready for immediate use without requiring additional hardware for rod attachment.
• Zinc-plated carbon steel construction - provides a corrosion-resistant finish suited for dry, interior environments while maintaining the structural integrity expected from a steel fastening component.

Why This Product

• No predrilling means faster installs - the self-drilling point drives directly into steel members ranging from 20 ga. to 12 ga., cutting setup time and reducing the number of tools needed on site.
• Purpose-built for horizontal rod suspension - unlike vertical rod hangers, this anchor is specifically designed for side-of-member attachment, making it the correct solution for applications where threaded rod must extend laterally from joists, columns, or overhead framing.
• Broad application compatibility in one anchor - a single product supports pipe hanging, fire protection, electrical conduit, and cable-tray installations, simplifying procurement and inventory for contractors working across multiple trades.
• Backed by Simpson engineering - produced by a recognized name in structural fastening, this one-piece anchor system is designed to deliver consistent, dependable performance in the approved interior applications for which it is rated.
