Dynabolt vs expansion bolt

Wedge anchor s , also known as expansion bolt s , expansion anchor s and projection bolt s, secure themselves using a mechanical wedging effect at the end of the fastener. There are three basic styles of wedge anchors: fully threaded, partial threaded and the full-bodied wedge anchor. [5] As shown in the figure, tightening the bolt results in a wedge being driven up against a sleeve. This jams the end of the bolt, and provides the strength. Many different manufacturers provide a variation on this theme, usually depending on the condition of the concrete, and the type of load. If a mechanical anchor fails, it is usually in the form of pulling out a wedge of concrete, and for this reason, proper design looks at the depth of embedment and ensures that the bolts are not spaced too closely.

The whole fence is already manufactured and sitting in my yard ready to install, so I can't change the fundamental design. Just need to make up my mind about the bolts.

The fence is meters high above the pool. Below the pool is meters, (thus 3m long posts). I didn't think I'd have a problem with blow out, since the concrete is over 6 inches thick, and those anchor screws are recommended for near edge fixing. But now enough of you have mentioned it to have me thinking about that too now.

Seems the one thing everyone agrees on is an epoxy set system. Guess I can do that with a stainless stud so I don't need to worry about it rusting? I'd do 10mm studs with what, a 13mm or 14mm hole in the cleat for expansion?
