A fastening assembly includes: a panel defining an aperture; a fastener having a cap and a shaft extending from the cap, the shaft being disposed through the aperture, the fastener having a first corrosion rate, and the fastener including: a recess formed in the cap and extending at least partially around the shaft; face surfaces that are planar and that are to directly contact the panel; and recessed channels that are disposed between the face surfaces, respectively, that are recessed relative to the face surfaces, and that extend from a radially outer edge of the cap to the recess; and an anode insert disposed in the recess and having a second corrosion rate that is faster than the first corrosion rate.
