Stupid question for a stupid mistake

[Challenger85]

Installing my 2” lift I wasn’t paying attention and I grabbed SAE hex bit for the shock relocation brackets and they’re metric. I went and got a set in MM but unfortunately the damage to the hex was done from trying to tighten and they are required to be torqued. Can I replace these bolts with the same size from a hardware store or is this something I have to get from AEV? I don’t know if they’re a special compound for extra strength? Anyone know?

I would think a grade 8 bolt would do, 150,000 pounds per sq in tensile strength.
look at the top of the bolt the lines on it will tell you the grade.

The bolts should have a designation on the end like 8.8, 5.8, etc. This is the "hardness" (sort of) of the bolt. If you know that and the size/pitch, like M12x1.75 then you can replace them from almost anywhere.

The grade marking on the head will tell you what strength of replacement bolt you need. In metric, that could be 8.8, 10.9, or 12.9 with higher strength as the number increases. Compare to the stock bolts and be sure to use at least that strength, even if the aftermarket bolts were weaker.

#5 in the diagram is the oem bolt (M12x1.5)

I would go with factory equivalent. Remember this.... Thomas Edison did not fail a thousand times while inventing the electric light, he found a thousand ways NOT to invent the electric light.
