But don't use hardware store grade 8 nuts (if that's your plan).. The flange design of con rod nuts is as important as the material/strength.
ARP makes nuts in various threads and are cheap enough to not mess with hardware store junk.
It was never my intention to use "hardware store nuts." I was trying to find some specifications on OEM nuts without much luck. In my application, I believe it is not necessary change my rod bolts, (however, I may just cave and spend the money for the new bolts and resizing the rods, est. $150.00) but would like to just change the nuts. The OEM nuts are not "flange nuts, which seems to be all that ARP has. Fastenal has a grade 8 3/8 24, yellow zinc plated nut, (made in China) which seems to be where all this stuff is coming from.
