Driver seat-belt bracket removal

Hows it going everybody. I am removing all the ceiling panels in my bus except the first one directly over the driver seat. The removal was going great, but im stuck trying to get my last panel out. I worked from the back to the front and now I am struggling to get the second panel out because the bracket that holds the driver seat-belt is fastened into the metal frame and the fastener they used looks like a metal cylinder around a threaded bolt. It is smooth and has no place to grab on to. I have tried vice grips and they spin, but don't un-thread. I will try to post pictures. thank you

You could use angle grinder and grind them off if they are not to be reused.

If you want to preserve the bolt, grind a flat in the side of the cylinder to grip perhaps.

Looks like the back side of a huck bolt. There must be a way to get at the head.

Thanks for the responses guys, I would like to reuse them I just have to take it off to remove this last ceiling panel as the bolts go through the panel itself Iíve tried to find the top of the bolt but itís impossible to get close enough to top to see it. Iím very defeated on this one I may just carefully cut around the profile of the bracket and remove it that way. Iím going to fiddle with it now. Iíll update you guys if I figure it out thank you

maybe use a new cutting wheel on an angle grinder and cut away at silver part without touching the threads. they might break off with a heavy persuader and screwdriver or chisel then. Always something new every day eh? Good luck!

You can try a pipe wrench, grind flats on corresponding sides so an adjustable wrench would help, a lot of auto parts stores also sell nut splitters that might help.
In my opinion?
They look like a soft metal so even if a wrench gets them off then they will probably to egg shaped to reuse which might be why you are having a hard time getting them (factory technique was to torque down until they distort which keeps them from backing out) which leaves you hunting for the proper threaded lock nuts to re use the same oddball bolts.
I would cut them off and use brand new graded bolts,nuts,and everything for a seatbelt harness.
I save and reuse every screw,nut,bolt, etc.. But when it comes to the seat belts I replaced everything and added some extras. Being cheap on a lot things are fine but with safety in mind a seat belt mounting point is not it.
Good luck

They are swedged-on. They don't thread.

Were they possibly installed before the outer skins or something?
Am I wrong or would it be easiest to simply grind em all off and rivet the thing back on when you're ready. Rivets are PLENTY strong.
I've got hundreds of steel 1/4" pop rivets, I'll send you five or ten for postage if you want.

Just responding to the post?
There are several threaded connections that look like they are swaged on but the bolt actually has a cut in it from the tip to the proper depth of the retaining nut and then the nut metal is chiseled down into the bolt to form a lock.
And in my world sweadged/swaged does not form anything that locks it is just a form of opening one piece of metal up big enough to receive another piece of metal into it but it still requires some form of mechanical attachment.
Welding,brazing,key way and set screw, pilot hole for the spot welder to get to the main bolt?
I would cut the stuff off and go back with brand new graded bolts,nuts,lock washers so I knew exactly what I had holding mine or my family's seat belts.
To me swaging/sweating is a friction fit?
Why in the hell would anyone accept a friction fitted piece of soft metal on a seat belt attachment point?
I am sure the engineering is there and thats why there are many of them but for me and my family that just ain't gonna cut it?
My seven seat belts are in the bus chassis (not the frame) and are more solid than any old or new bus on the road.
But I do do steel work for a living and tend to overbuild on anything personal?

We have a business in town called "Industrial Fasteners" and I'm sure there's one somewhere around you too. They should be able to identify the fastener system used and how to deal with it.
