Bow cleats
Because the movement of the cleats may have caused any sealant/bedding compound to lose its sealing capability, you may want to rebed the cleats and bolts with bedding compound (polysulfide /aka BoatLife Caulk/ for example). Thus, you would remove the cleat and bolts first before reattaching using caulk on the bolts. But then again, you may want to go a step further to insure that you never have a core problem (due to water intrusion) if the sealant fails in the future. You could put a piece of tape over the side of the hole in the anchor locker, then inject penetrating epoxy into the holes (to penetrate the core surrounding the hole), wait for that to cure, and then rebed the cleats. Or drill oversize holes for your bolts, fill the oversized holes with epoxy mixed with filler, wait for that to cure, and then redrill properly sized holes and bed the cleats. Either way, there is more involved than just tightening the nuts on the bolts. That is because there is a core material (wood is subject to rot if left wet for long periods), and water may have entered your core already; so you have to check the core by removing the bolts to see. Lastly, because you now have the bolts out, you might as well go an extra step to prevent a potential problem in the future.
