Series CFH & CFHN self-clinching heavy duty steel nuts are designed to provide durable load-bearing threads and high installation performance in sheet metal assemblies. Available in both heat-treated and non-heat-treated carbon steel versions, these fasteners offer an efficient upgrade over conventional weld nuts with reduced manufacturing and installation costs. Engineered for high pushout and torque-out resistance, the self-clinching design eliminates welding operations while ensuring secure permanent installation. Supplied in plain and zinc clear finishes, CFH & CFHN nuts are suitable for industrial equipment, structural panels, enclosures, and heavy-duty fabrication applications.
