Expansion bolts boxbolt for structural steel are mechanical fasteners typically consisting of a bolt, an expansion sleeve, and a cone-shaped nut that, when the bolt is tightened, is driven up inside the sleeve to create a wedging effect and expand the fastener (Figure 2). This 'blind connection' technique can just as easily be used to connect to the web of another structural section type, such as a wide flange beam. Unlike conventional bolted or welded connections, expansion bolts can be quickly installed by simply inserting the fastener into a pre-drilled hole and tightening with a torque Wrench. Due to the faster installation process, work in the field is reduced and, therefore, the cost and timeframe of the construction project are decreased.

These expansion bolts are suitable for structural connections due to their capability to resist loading in both tension and shear. For example, the allowable load values for a 3/4 inch diameter bolt are approximately 12,500 pounds for tension and 11,500 pounds for shear. Product sizes range from 5/16- to 3/4 inch and the total material thickness clamping range is from 1/8-inch for the smallest diameter to 3-3/8-inch for the largest diameter.

one is carbon steel,another is 316 stainless steel(the price is more higher than carbon steel).

Also,the carbon steel expansion anchor bolts has two surface treatment,

one is hot galvanizing,the other is zinc.
