Rivnuts or Bolt, washers, lock-tight with nuts

Rivnuts or Bolt, washers, lock-tight with nuts

Postby bradaskins [OP] » June 4th 2020, 12:19am

Saturday is the day. Installing a roof rack.

I have two options
Rivnuts
Bolts and nuts.

The headliner is out so I have plenty of access to attach the roof rack.

What would you do? Rivnuts or bolts, washers, lock-tight and nut?

Silicone Caulk in the Hole/Bolt/Washer/Lock Washer/Lock Nut.

Loctite will end up all over you and the floor.

I like to mount trough the Roof Crossmember. Even when doing so, I've dented the roof on a few vans, so I can imagine what would happen If bolting through just the roof skin.

Drive it around for a week, and retorque the bolts, before reinstalling headliner.

My plan is to use 22 gauge steel plates on the inside of the ceiling for extra support. The feet on the rack don't all line up with the ribs of the ceiling and they aren't adjustable.

Why will loctite end up all over the place?

Lol you can locktite if you want, I have no idea what that comment was about, the sealant can get messy.

I used bolts/washers through the cross members, I used several washer wrapped in electrical tape as a spacer between the small gap from the cross member and ceiling, I saw someone else do this I am sure. I sealed with a heavy black tar like sealant, it is not normal silicone maybe roofing stuff it has been forever now I forget, it was messy but has been fantastic for this and my solar wire holes. If you want I can look and see what I used.
It has been leak and problem free for about a decade but I am in Socal so it gets less rain. Had plenty of rain during 2 years in Mexico, C. America, and Colombia though, and if it does ever leak I will just add some more sealant.

In hindsight, I would have rather attached the solar panel directly to mounts on the roof, and skipped the rack altogether as I rarely use it, but it is strong as I have climbed around on it before.

I used bolts, fender washers and nylon locknuts. I put a blob of silicon on both sides of the hole. It worked for me, doesn't leak.

I spent many years as a sheet metal fabricator and used both types of fasteners. I've seen a lot of rivnuts fail, loosen up, spin or pull out. I would always prefer through bolting whenever possible. If you do decide on rivnuts, go with stainless steel, much stronger.

Or you could use a plus nut - it's like a beefier version of a rivnut.

Loctite is very watery, and you are working with it up in the air.

It isn't going to Drip Up!

I'm only planning on using enough Loctite to put on the bolt threads. You think that is going to dip a lot?
Guess I plan on putting down a painter's cloth.

Roof Rack Installed

Postby bradaskins [OP] » June 8th 2020, 2:05pm

Yesterday was a little nerve-wracking. After a week of measuring and prepping I finally put the drill to the roof of my van.
It was a rack off of an '05 Suburban my van is an '04 it was almost a perfect fit.
It even passed the hose test, no leaks.

Congrats, looks solid.

I suggest posting this in your original roof rack thread sine it had so much relevant information for others, that way when people search they will find the question as well as the final product in the same thread, rather than having two search for 2 threads.

Good call. Is there an easy way to do that? I don't see how to delete a post.

Probably doesn't matter much, I would just copy the pics/info into the other one while leaving this thread as is, if a mod cares they can merge them, but I was only thinking about it from someone finding the other thread, it is nice to see the finished product.

What did you use for the white sealer on the top?
It looks like clear on the underside.
The fender washers are perfect in that application.

Also, have you put the headliner back in yet?
If so, how difficult was it to get back in place, and fitting properly?

I used a heavy-duty Chaulk and clear silicon on the inside. Why, I don't know, I just did.

I have not put the headliner back in yet. I wanted to observe the bolts, nuts, washers for at least a week.
Also, the next project is installing a solar panel and still need access to the ceiling for wires.

To get started - press "REPORT" - go from there. They'll know.
Might be good to have the URL to the other thread.

Well, after all... what would Banacek say ?... Anyone that condones the actions of the American People during the Storming of the Capitol are as complicit as the Assholes themselves.
But no way does this let the Democrats or the MSM off the Hook.
