I need to refurbish/replace the engine stringer mounts in my boat. There are 5 bolts on each side: Are these lags bolts, threaded bolts with nuts, or bolts screwed into inserts? I am afraid to use force to back them out. I'm guessing they are lags: The 9/16" head is stainless steel. Any ideas? Thanks!
