Details of the events surrounding these pictures are intentionally vague (for now) but it appears there may be good news on the horizon and soon I may be less vague about what's going on. Oh, and why I'm calling it the WTF challenge should be fairly self explanatory when you see the photos below....
SO! How would YOU go about removing these gnadgered-up studs? What they appear to be (or were) is 316 stainless machine screws with a phillips head. I can access the back side of some, perhaps all of them, and they appear to be threaded into stainless sleeves which are epoxied into the solid fiberglass deck. Oh, how I wish this was addressed correctly in the beginning before the bolts were all gnadgered up, but it wasn't, so this is what I have.
I haven't really tried to remove them yet. All I've tried so far is applying Kroll penetrating oil once, and I put a vice grip on them and was unable to get them to budge. The yard says they tried to budge them (not so sure about how hard they tried) and say they can not be easily removed.
A prize will go to the person who has the idea/technique that will successfully remove these bolts!
