How deep should anchor bolts be in concrete?
Steps to Installing Concrete Fasteners The hole should be drilled 1/4″ to 1/2″ deeper into the base material than the anchor will penetrate. This allows for any material to fall when the anchor is inserted into the hole. After the hole is drilled, it must be cleaned of all debris, material or dust.

Do bottom plates need to be pressure-treated?
Both wood and concrete wick water well because they are porous materials. Pressure-treated bottom plates deal with the symptoms of the problem when a capillary break between wood and concrete deals with the cause. No direct contact, no need for pressure-treated bottom plates.
How far apart do anchor bolts need to be?
