Use a magnet to find if it is regular steel or stainless steel. Compare with a bolt same diameter of steel and another one from stainless steel. Compare those two with the one in your keel using the magnet.
No need to try to find out what or how Pierson did it: just determine using handbook and materials at hand.
p.s. I think Pierson is part of TPI now.
I'm slowly inching my way towards a decision. I may not be in the ballpark but at least now I know where the ballpark is. I am inclined to torque it "clean and dry" in order to remove as many variables as possible. I have no expertise or experience, a deadly combination. If I do lubricate, it will be with a light oil
like wd40, which has a lube factor of 0.8, to prevent galling.
I'm using Life Kaulk as bedding material, letting it set overnight before torquing. I think I'll treat with a little penetrating oil after, to displace any moisture, and coat with marine
