ARP, DSE body bolts, etc... are VERY strong. See the link below for McMaster-Carr 12-point stainless cap screws with 170ksi tensile strength.

This.

But, it also applies to the stainless fastener kits sold by the repro parts houses. From a structural standpoint, most all of it is of unknown quality, specifications, etc. I trust none of it.

Let's not delve into proper length specifications for double shear just yet either. ..... ;-)
