What grade bolt do you recommend for Power Racks>

[JBlack]

Hi Rip,
From reading your book and watching the newest video, I was wondering what grade of hex nut you use for racking the bar on your i-channel racks.
(I also see bolts used on the EFTS racks.)
Did you use a Grade5 or Grade8? Or L7?
Many thanks.

I have 8s in one rack and ungraded bolts in the other. I don't think it matters much because you will never exceed their shear strength with a loaded bar, and they will both flatten your bar's knurl just as happily.

Thanks for the reply and running this great forum, I appreciate it.
