Bi-Metal Concrete Screw Anchors
《Feature & Benefits》
Threaded screw anchor comes with many distinguishing benefits such as their non-expanding, removable characteristics, among many others. The large diameter screw anchors and their nature to handle high loading jobs makes it natural for them to be used outdoors. Bi-metal screw anchor uses stainless steel in the loading area; combined with carbon steel only for the purpose of threading in the concrete. Depending on the stainless steel used in the loading area, its product life could last up 50 years.

It's worth having a couple of screw sizes on hand if you do a lot of projects.
Holes for concrete screws should be at least 1/4 in. deeper than the screw will penetrate to allow a little extra space for dust accumulation from the drilling process. See the illustration above.
