Wedge Anchoring System - Hilti

In class earlier today there was a discussion about Wedge Anchor Fastening systems. I have had plenty of experience using these while working at FDH Engineering. These types of fasteners are typically used to connect structural steel to concrete. I am familiar with Hilti products so I have attached the link to these types of fasteners here: http://www.hilti.com/holcom/page/module/product/prca_catnavigation.jsf?lang=en&nodeId=-10929 and below have posted a picture of one.
