Stewart Fastener J7173 Concrete Hangermate 3/8 in Vertical 20pk

Product Description

The STEWART FASTENER J7173 is a Sammy Concrete Hangermate designed for vertical rod suspension into concrete ceilings and overhead concrete structures. This anchor accepts a 3/8-inch threaded rod and is engineered for fast, reliable installation without the need for a separate sleeve or insert. Each jar contains 20 anchors, making it a practical unit for job-site use. Mechanical, plumbing, and electrical contractors rely on this type of anchor when hanging pipe, conduit, duct, or threaded rod from poured concrete overhead surfaces.

This anchor is suited for commercial and light industrial applications where threaded rod hangers must attach directly to concrete ceilings. Typical installations include HVAC duct support, conduit runs, sprinkler pipe hangers, and plumbing drop rods in concrete-framed structures. The vertical orientation means the threaded rod hangs straight down from the installed anchor, which is the standard configuration for overhead mechanical system support. The 20-count jar format supports efficient inventory management on multi-trade job sites.

Key Features

• Accepts 3/8-inch threaded rod for vertical suspension from concrete
• Vertical orientation for straight-down rod hanger applications
• 20 anchors per jar for job-site convenience and inventory efficiency
• Designed for direct concrete overhead installation without separate sleeve inserts

Compatibility

Designed as an OEM-style concrete hanger anchor compatible with standard 3/8-inch threaded rod used in mechanical, plumbing, and electrical overhead hanger assemblies in poured concrete structures.

Installation Notes

Installation is performed by licensed mechanical, plumbing, or electrical contractors using a rotary hammer drill sized to the anchor specification. Always verify the concrete substrate meets the minimum thickness and strength requirements for the anchor load rating before installation. Shut down and de-energize any nearby systems before drilling overhead into concrete. Follow applicable codes including NFPA 13, IPC, and NEC for hanger spacing and load requirements in your trade application.
