Review on Ultimate Fastening Solution: SNUG Fasteners SNG999 Twenty Premium by Michael Radhakrishnan

I have used many different concrete anchoring systems over the years and love the style. It's important to drill an exact size hole in the concrete because if you drill a hole that's too big, it won't harden. You must provide your own washers and bolts to use these anchors as they only perform part of the nut's function. However, they are easy to assemble and hold up very well.
