KFB3™ Broach/Flare-Mount Standoffs

PEM KFB3™ Broach/Flare-Mount Standoffs are designed to hold a fixed gap between two panels through a static attachment. These standoffs offer greater pullout performance in PC board materials. The KFB3 standoffs are designed for unplated mounting hole applications. These standoffs feature brass or CDA-353 brass fastener material. The KFB3 standoffs are used in aerospace, defense, telecom, datacom, and automotive electronics applications.
