ARP Hardware question

[brently]

Ive been working on a forged internal build this past winter, and have been using all ARP hardware including mains, rod bolts, and head studs. My question is, I am missing one head stud nut. Should I replace it with one from the hardware store? Maybe a grade 8 or 10? Not sure the strength of the ARP nut. Or should I purchase and ARP replacement nut? Thanks for the help guys.

I would highly suggest getting another one from ARP.
