# What size fasteners should I use to mount fence bases to concrete?

We're anchoring several 4" x6" x 1/4" steel plates to concrete. They will be used for a fence. These bases need to be solid, but it's simply to separate one area from another (people won't be near it).

Initially, we were going to use these 3/8" x 3" anchor screws, but someone here mentioned expansion type anchors. I started searching to see what this is, and found several images: Image1, image2, image3.

Are these anchors stronger than the 3/8" x 3" anchor screws? Can these anchors be removed in the future?

• The stress on a fence isn't normally from human activity. It's from the massive amount of cumulative force the wind can create. That, coupled with the torque multiplication those small bases create, means that you could have hundreds of pounds of pullout force being applied. – isherwood Mar 25 '18 at 13:08
