Self-grounding standoffs are purpose-built for applications where printed circuit boards need to be securely grounded to steel or aluminum chassis. These standoffs are designed with projecting teeth that establish a reliable electrical connection with the circuitry on the board. This eliminates the necessity for additional hardware like serrated or star washers.

These industrial fasteners are available through OneMonroe Fasteners and can be obtained with quick delivery times. They are a practical solution for ensuring electrical conductivity and grounding in situations where circuit boards must be firmly and securely connected to metal chassis.
