HF trailer bolt grade

[nikwax]

I apologize, I can't find the original thread, and in a "weld vs. bolt" debate someone asked about the grade of bolts that came with HF trailers. Mine came with ISO R898 Class 8.8, which is Alloy Steel, Quenched and Tempered, and has the same mechanical properties as SAE J429 Grade 5 or 5.2. Also comes with nylock nuts. They will definitely take quite a bit of torque.
