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