Have someone weld flanges to your fence posts, or square plates with 4 holes in the corners for bolts (I'd make them at least 7/16" holes for 3/8" bolts). Then you can drill the concrete and drop in some Redhead anchor bolts, set the post, and tighten them down on the bolts.

There are several accepted methods.
1. Use a masonry bit and drill a hole for a lag screw anchor. Bolt a bracket that fits a 4 x 4 post and fit the post to the bracket. Do this at least every eight feet. Mount you fence to these posts. This method has the least lateral strength.
2. Cut a hole in your concrete for each post using a carbide blade in a circular saw. Dig out the dirt under the hole and set the post in it. Fill the hole with quick setting concrete post hole mix. Allow to set over night and mount your fence to the posts. this method has the most lateral strength.

Use a gunpowder activated fastener, hand held device to fasten the fencing hardware to the concrete. You can rent them at your local rental yard. Look in the web at http://www.patmi.org and you can get good info there. Lowes has all of the hardware you will need for this project. Good Luck !! Remember to keep everything straight and level.!!
