Elevator Bolts

Good Morning
I have a question on installing elevator bolts ? I am in the process of gathering my material for the spring when I plan on removing the shell on my AS 1974 Overlander. The bolts that were installed at airstream seam to be made of carbon steel and are 1/4" X 2 1/2" long. Has any one out there replaced them with 5/16" or 3/8" stainless steel elevator bolts? Or did you use the carbon steel bolts. I would appreciate some feed back on this as i have located a source for the stainless steel bolts.

I just finished redoing the rear floor in my safari and just used steel bolts. I didn't bother with stainless as I thought if there was enough moisture to rust them out, my wood floor would be long gone even though I soaked my wood floor with polyurethane finish prior to installing.

Not on an Airstream, but on our 42' pontoon houseboat. I used steel elevator bolts. If a part of the deck had to be replaced, I would remove the bad wood, giving me access to both ends of the bolt which would get replaced with new anyway.
I wouldn't bother getting the high priced spread.

new technology

Make the switch to new technology. If these flooring screws had been available to early Airstream builders they would have been used. Way better, made for flooring, self tapping, in expensive and fast/easy to install.https://www.fastenal.com/web/product...%20Screws%22|~

I used steel for my last project.

The frame will corrode before the bolts will, because it's thinner. Stainless steel bolts are weaker.

Thank you for your inputs for the elevator bolts. I went out end tried a 5/16 bolt to see if it would fit I to the bolt holes and found out that the 5/16th bolt was to large for the hole. Still has any one replaced the elevator bolts with stainless steel instead of the carbon steel bolts?

I replaced the floor in my motorhome with 1/4"-20 stainless steel machine screws from Albany Fastener on E-bay. They were very reasonably priced and they shipped really quick. The screws were flat head with an Allen drive You can get a lot of torque on a Allen head. I used a tap to cut the threads which is an extra step compared to using cutter screws but, it worked really well.

Jammer makes an important point. Look up torque and tensil strength tables for stainless vs steel. I replaced my entry door hinge bolts with 1/4"-20 stainless, and was able to snap off two of them without much effort using a short handled rachet.

If they are to be covered, I'd just go with cad plated e bolts.

I just discovered after dropping the rear belly skin that the guys that replaced the last 4' of the floor used screws to secure the C channel to the the floor. But they didn't go through to the rear frame channel

Now that the inner panels are in and a bunch of systems are installed on them, what to do to install elevator bolts ?

Light bulb ! 1/4" x 3" toggle bolts installed from the bottom ! Ya, I know, I know it seems odd but what am I to do tear out all the work to install elevator bolts, Not !

They have a rating of 90# in dry wall and they pulled the floor tight so I'm happy.

The big pain was using a 11/16" hole saw to make the holes and digging out the cores. On the plus side I now have a bunch of 1/4" washers made from the Airstream
