Most of the posts have a hole in the center that will need to be drilled and tapped for whatever thread pitch you will use.

Many of the manufacturers of extruded t-slot frames will offer both metric and standard sizing, and the center bore will generally accept either a self tapping screw or be easily threaded (it's aluminum) to match either metric or standard. In other words: if it's a metric t-slot, you can pretty easily use a metric screw or bolt - if it's a standard t-slot, a standard screw or bolt will work. They will generally recommend a specific thread diameter and pitch for use in the central bore, such as M6-10 or 1/4"-20tpi.
