There are many types of fasteners, and many people do not know what the difference is between the car repair gecko and the expansion
Screw as a new anchoring material, the following are listed for your reference:
The main material of
Wedge Anchor is carbon steel and
Stainless Steel, grade 4.8, 5.8/6.8, 8.8, etc., the standard is DIN, ANSI, BS.
It is mainly composed of bolts, Clip, Flat
Washer and
Nut, and some customers will also require Spring Washer.
How it works:
The end of the tube inserted into the hole of the tube plate is rolled by Wedge
Anchor, which causes the inner wall of the tube to expand continuously, resulting in plastic deformation. The diameter of the tube increases, the tube head is completely fitted to the hole wall of the tube plate, and the tube plate is forced to produce elastic deformation. When the tube expander is removed, the elastic deformation of the tube plate wants to return to its original state, but the plastic deformation of the tube end cannot be restored. As a result, the tube plate holds the tube end tightly, so as to achieve the purpose of sealing and firmly connecting the two.
What is the difference between Wedge Anchor and expansion screw?
• Expansion screw is mainly used for external wall supports, electrical supports and other objects with low load-bearing requirements. Wedge Anchor is mainly used in railings, seismic supports, elevator supports, shelves, glass curtain walls
• The diameter of the punch is consistent with the diameter of the product; For example: m12*100 aperture is 12mm
• Compared with Expansion screw, it is more economical, not easy to loosen, and the hole depth is not high
• Greater tension value.
