Seems to be a good product, why the 2 stars is I was under the impression this was a set of countersinks, I only got 1 countersink, it says 1/2". This is what the heading on the product says. Seems I am missing a few. Any answeres would be appreaciated.

Worked well. Wish that they dug down deeper to incorporate the bolt and a 1 inch washer.
