Choosing the Best Anchor to Fasten to Concrete - Concrete

Nov 24, 2020 · Mechanical type concrete anchors deliver their holding values from friction. Once the friction is broken, the anchor will gradually lose its holding values. Concrete anchors in a vibratory load application may loosen or break up the concrete in the hole where it is placed. The working end of the anchor can push against the walls of the hole in
