There are many types of fasteners. As a new anchoring material, many people still don't know the difference between anchor bolts and expansion screws. Here are a few points for your reference:
The main materials of Wedge anchor equipment include carbon steel and stainless steel. The grades include 4.8, 5.8/6.8, 8.8, etc. The standards include German, American and British.
It mainly consists of bolts, clips, flat washers, and nuts, and some customers may also require spring washers.

working principle:
The end of the pipe inserted into the hole of the tube plate by the repair gecko tool is rolled, causing the inner wall of the pipe to expand continuously, causing plastic deformation, increasing the diameter of the pipe, and the pipe head completely fitting on the hole wall of the tube plate, and forcing the tube plate to produce elasticity. Deformation. When the pipe expander is removed, the elastic deformation of the tube plate will return to its original state, but the plastic deformation of the pipe end cannot. As a result, the tube plate will tightly hug the pipe end, thereby achieving the purpose of sealing and firmly connecting the two.

What is the difference between Wedge anchor and expansion screws?
• Expansion screws are mainly used domestically, while vehicle repairs are mainly used for export or domestic elevator installations.
• The punching diameter is consistent with the product diameter; for example: m12*100, the hole diameter is 12mm
• Compared with expanded wire, it is more economical, not easy to loosen, and does not require high hole depth.
• Greater pulling force value
