Series CFSOSG & CFSOAG self-grounding standoffs are designed to provide secure mechanical mounting and reliable electrical grounding of PC boards in steel and aluminum chassis assemblies. Integrated projecting teeth penetrate conductive surfaces to establish consistent electrical contact with PCB circuitry, eliminating the need for serrated or star washers. The self-clinching design enables permanent installation with high retention performance in sheet metal applications. Manufactured in passivated 300 series stainless steel and 7075-T6 aluminum, these standoffs are suitable for electronic, telecommunications, and industrial equipment requiring dependable grounding continuity and vibration-resistant assembly.
