This is a super soft M3 damper standoff from Matek. Originaly designed to be used with the Matek F405 flight controllers for the ICM20608 32Khz gyro, you know this vibration damper will work well. This rubber damper is M3, so it will be compatible with most flight controllers and frames on the market.
The threaded part of this screw is 4.5mm, but the overall height of the vibration damper is 7mm.

Very important part of a quad pilots kit, especially if you want your flight controller to preform to the best of it’s ability, I always use these for extra smooth flying and jello free HD video. Highly recommended.
