I'm not sure if it is exacltly 6 inches., but it's close. I use a Danforth style anchor that is made by Super Hooker and weighs 9 pounds. I checked the fit very closely before I drilled the holes! I wanted to cut it as closely as possible so my cover will still fit! By the way, I have to take the anchor off before I cover the boat, but the bracket fits.
