Head stud/nut question...stupid but urgent
Alright so I'm assembling my engine and after BS on top of BS there is some more BS. Some bolts got broken off into my head from the cam caps so I had to take my head to get the bolts out. But the head stud nuts and washers were not taken off before the head was moved to my car(I didnt remove my head, kind of wish I did). Now I'm missing a ARP head stud nut. I looked all over for it to no avail. A friend recomended going to lowes and picking up a heavy duty nut or something but I dont know if I want to trust some random lawn and garden store hardwear in my engine. I want to know what some of the people who have experience with this feel about it and if a lowes nut would be able to deal with the pressures acting upon the head during compression and combustion.
At this rate I'm never gonna get **** done!!

if it's just one nut i don't see a problem. just find the nut with a rating that is equivalent to the arp nut and you should be fine. although, i know summit has arp nuts so you might want to look there.

the reason you probably never have problems is because a grade 8 nut with the proper thread has a rate of about 150k psi. idk the metric equivalent of a grade 8 right off the top of my head but any quality hardware nut should be fine especially if it's just one that will be used.

I've had friends that have broken lowes bolts on their axles while drifting. It may or may not work but at this point I really dont want to take the chance. Especially with something inside my engine....
EDIT: I just went to home depot on saturday and didnt see any grade 8 hardware at all (they barely had any hardware to tell the truth).

you wont be able to find any grade 8 nut for the studs though because if the thread being metric. that's why i said equivalent, if you can find a grade 12 metric nut you should be fine. they have a rate of about 170k and change psi.
EDIT.
now that i had a chance to get way from my pc and actually think i just remembered that head bolts for the ka are grade 12 so a grade 12 nut is exactly what you need.
