Thomas Betts SSF-BH1/4S Hammer-on Flange Clip 1/4-20

Product Description

The THOMAS BETTS SSF-BH1/4S is a hammer-on flange clip with an integrated stud, designed to attach threaded rod to structural flanges without the need for bolted fasteners. Made from anodized spring steel, this clip accepts 1/4-20 threaded rod and supports a load capacity of 100 lb. Flange thickness compatibility ranges from 1/8 inch to 1/4 inch. Installation requires only a hammer strike to seat the clip securely onto the flange, making it a common choice for fast, one-hand placement in tight spaces. Electricians, plumbers, and HVAC mechanics use this type of clip when hanging conduit, pipe, or ductwork from structural steel flanges.

This clip is used in commercial and industrial construction where beam flanges serve as anchor points for suspended systems. Typical applications include hanging threaded rod from I-beams, channel iron, and similar structural members. The 1/4-20 stud threads directly into standard rod coupling nuts or strut hardware. It is well suited for electrical raceways, mechanical piping systems, and HVAC duct hangers in both new construction and retrofit work.

Installation Notes

Installation is performed by a licensed electrician, pipefitter, or mechanical contractor as part of a suspended support system. Before installation, verify the structural flange thickness falls within the 1/8 inch to 1/4 inch range. Position the clip on the flange and strike firmly with a hammer to seat the spring steel jaws. Follow applicable NEC or IPC guidelines for support spacing and load ratings when integrating into a hanger system.
