The Expansion Anchor Bolt is used to make connections to structural steel sections. The Expansion Anchor Bolt is suitable for use with rectangular, square and circular sections, or other types of steelwork where access is restricted to one side only. It eliminates the need for access to both sides of the connection and only requires a clearance hole to be drilled to suit its outside diameter.  The holes can be drilled off site for new projects where the position of the holes can be detailed or the holes can be drilled on site for retrofit applications.Description:

There have M6.M8,M10,M12,M16,M20 Anchor Expansion Bolts in the form as below:

Expansion bolts 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.

This M8 expansion anchor bolts have three dimensions:
M8*14*50mm
M8*14*70mm
M8*14*90mm

Expansion Anchor Bolt Features
Simple Connections to structural tube
Guaranteed Safe Working Loads
5:1 Factor of Safety
Hot Dip Galvanized for corrosion protection
Also Available in zinc plate finish or stainless steel
Large combined material clamping range
Special lengths available
 
expansion anchor steel applications include the connection or suspension of:
 
* Primary Steel
* Secondary steel
* Material Handling Equipment
* Lifting Equipment
* Wall Ties
* Cladding
* Curtain Walling
* Electrical Equipment
* Blast Walling
* HVAC Equipment
