    I have four CBS66 post bases installed into 4 12″ tubes 24″ deep. They only have one nail/screw hole on each side along with two 5/8″ holes for what I am assuming are for bolts.

    What size bolts And washers (L & thickness) do I use to install the posts? I have seen bolts with both flat head and heads with a square head washers can’t fit around . I hope I’m making sense.
