Unless you plan on burying wood in concrete (which I didn't) I highly recommend using ABA44Z connectors. You will need a 3" or 4" bolt to set into the concrete as you pour. Then simply slide the connector over the screw and tighten with the nut. Then plug your 4x4 into the slot. How easy is it! Also, 4x4 will not rot over time.
