I just want to go to Home Depot or something and pick up a couple. Anyone know what size they are off the top of their head?

Header Bolts – 3/8”-16 x ¾”

Those will work from Home Depot

Get some Grade 8 or similar, even though you do not need something of that strength. I would get it for extra measure.
