Assuming I did that right but I don't guarantee it.

I think you are correct.
However the bolts have already been returned so I supose it's academic now.
You may have a Nut & Bolt / Fastener store in your area. I have one in Biking distance they have 20 times more selection than Lowes and are about 1/2 the price. May be worth looking in to if you need lots more bolts.
