Someone asked the thing on www.ask.com, What's the part called when you screw in a bolt, and it gets wider? It is the thing called expansion screws, also named concrete anchors/bolt. The bolt is usually used on glass balustrade. Pre drill the timber where you want the frame fixing, then spot through one of the pre drilled holes into the concrete.? Then insert a anchor and tighten it to hold it in position, then drill the rest of the holes in the concrete and knock the anchors in as you go. Once they are all in position you can tighten them all.
