Installing a Mantle Piece

Hey Guys,
I've got a reclaimed oak beam that I'm in the process of installing above a new stove.
I was going for a "floating" look for the beam, so I'm planning on using rawlplug projecting anchor bolts to fix the mantle to the concrete chimney Brest -

I was hoping to double check I'm on the right track, I'll using some bonding agent too to prevent the mantle from being pulled off the bolts once its affixed.

Any thoughts? Am I completely off track?

How are you going to 'hide' the head of the bolt. Would you consider a hanging system such as those on kitchen units.

The bolts in question don't have a "head" per say, I'm planning on drilling a hole in the chimney brest, into which the bolt goes and you torque it down with a nut and washer until the expanding section is pushed out which fixes it in the wall. About 90mm Of the bolt should be protruding out after this.
Then you drill receiving holes in the back of the mantle to which the bolts are pushed into to, thus suspending the mantle with no visible bolts or brackets.
Only downside is the bolts aren't fixed fully into the mantle, so that's where the bonding agent comes into play.

Got ya now. I thought you were drilling the whole way!

Nothing at all wrong with that plan. There is a type of epoxy for bonding steel bar into holes. Don't know name....

Only danger is you only get one go and ensuring its level from front to back(and stays level long term) could prove tricky.
