I apologize for my first post being a cry for help, but I need help.

I seem to have lost one of the four hand bolts that attach the upper portion of my SS tower to the lower portion (which is attached to the gunnels). I need to source a replacement. I have the local Cobalt dealer at Lake Lanier looking for the part, but I fear that it may not be available. Does anyone know who was the manufacturer of the SS towers on 2006 era models? Any suggestions as to finding this part if the dealer is unsuccessful? I am thinking that I may have to have a machine shop make one (or two). You can see in the pic that the port side front fastener is missing. I'm trying to attach a photo of the bolt, but the forum software is not accepting (says cannot verify size of photo).

Thank you for any help you may provide!

I can’t tell from your picture whether the knob is made from metal or plastic. If it the knob is plastic, maybe one of these would work? McMaster-Carr calls them “Large-Grip Plastic-Head Thumb Screws”.

Hey kda. So glad you found us.

It’s difficult to visualize without that close up pic. A trick is to screenshot the picture and upload the screenshot when you get that sizing error.

Give it another shot.

And welcome aboard mate!

Thanks for the responses! Gonna try uploading a screenshot of the fastener. What makes it a little more complex than a thumb screw is that it has a sleeve that reduces friction when laying down the tower (rotating about the fastener). And the sleeve has a tapered end (at the threaded end).

A picture with the fastener in place.

Thanks Titaniumboy, that would serve as a foundation for sure. 3/8"-16 thread, 1.5" long would work. Just need a sleeve of some kind if possible!

I think I bought the last one Cobalt had a few years ago. Roswell made that tower. I think you can get that knob from Sampson towers. It's all aluminum though. Other tower brands may work also. I wish I still had the part number but I don't. Sorry.
Maybe a dealer in the country has one. I had to buy it though through the local cobalt dealer.
