The Bulldog Heavy-Duty A-Frame Coupler, # BD44150WH301, does not come with the attachment bolts. I have attached two images showing the bolt pattern measurements and the bolt hole sizes. I would recommend using grade 8 bolts, but grade 5 is acceptable and the amount of bolts you will need will depend on how you plan on mounting the coupler.

I would recommend using the bolt holes on the side of the coupler to mount to your trailer. I spoke with my contact for Bulldog and he said you will need 10 bolts 3/8 inch bolts for the smaller diameter holes and two 1/2 inch bolts for the larger diameter holes. If you also wanted to use the three bolt holes on top, then you will want two more 3/8 inch bolts and one 5/8 inch bolt. We do not sell the bolts separately, but they can be purchased at your local hardware store.
