I personally would like to know what the grade of the 4 bolts are that hold the head to the base and the two bolts that hold the base together are if I owned one and towed heavy like I do.
Our previous conversation about this led my research to find that these are grade 5 metric equivalents. Nearly PSI for PSI.
I don't have the confidence to say they are grade 8 equivelant.
Here is a chart that should help some.
Chart
Seems that the eyeball size of the bolts are around 16 mm...
The proof load of a 16 mm 8.8 bolt is 600 MPa or 87,022.62 psi
So it has more in common with a grade 5 bolt than a grade 8 it's a little stronger than a grade 5 at 85,000 psi but no where near a grade 8 bolt at 120,000 psi...
But a grade 5 is more than strong enough for this application...
Those four bolts combine for 348,088 psi strength just in the bolts.
Thanks!

"Overseas", they carefully avoided saying China did they.
