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?
