Greg - Yes and No, they need to be threaded (tapped) OR you need to have nuts on the backside of the aluminum bar stock and longer bolts with flat washers - be sure to use an anti-corrosive such as Lanocote (Forespar) on the aluminum and SS fasteners. Butter 'em up. Quality fasteners are in order. You could use SS bar stock but that would be 'fun' to drill and tap - Bronze would also work here. GO In a message dated 5/4/2010 8:50:52 P.M.

I guess this is what you'de call them. Mine where loose so I tried tightening them and of course the 30 yr old bolt spapped like a brittle bone,,,no sweat I'll just slide the bolt out and replace....wrong...the backing bar? is aluminum, the bolts SS and the bars are threaded and the bolts are not going to come out...can I drill out the old bolts and just thru bolt back together or is the threading essential for strength...can I just toss the old backer and use a flat SS backing-plate...or are these a common item I can purchase at my daily sojourn to West Marine?
