It seems like you are supposed to mount your safety chains (criss-cross - just learned that) on the hitch receiver mounted to the vehicle. Does it not make more sense to mount to the FRAME of the vehicle instead? I used to mount to the frame. Kinda made sense - that if the hitch receiver failed...the backup would be the solid vehicle frame? Thoughts? I may be missing something.:B
The force required to shear either the pin that holds your receiver in place or the bolts that hold your hitch to the frame is so great that if it was ever exerted would also snap your chains instantly.
Putting them on the frame is useless.
Large Jet engines are often bolted to their mounts using bolts not much bigger (albeit grade 8) than that of your hitch bolts. I dont think you have to worry too much.
