Specifications:

1. Stainless Steel 304, 316, 316L, DIN, 201Stainless Steel Stud Anchos for Concrete

2. Stainless Steel Expansion Bolt is used to fixing component,industrial and construction fasteners.

The grades of expansion anchor bolts are divided into 45, 50, 60, 70, 80;

The materials are mainly divided into austenite A1, A2, A4;

Martensite and ferrite C1, C2, C4;Its representation method such as A2-70;

The front and back of "--" indicate bolt material and strength grade respectively.

(1) Bolt material Common materials: Q215, Q235, 25 and 45 steels. For important or special-purpose threaded joints, alloy steels with higher mechanical properties such as 15Cr, 20Cr, 40Cr, 15MnVB, 30CrMrSi, etc. can be used.

(2) Allowable stress The allowable stress of the threaded connection is related to the nature of the load (static and variable load), whether the connection is tightened, whether the pre-tightening force needs to be controlled, and the material and structural dimensions of the threaded connection.

The fixing principle of the wedge anchor bolts is to use the inclination of the shape to promote the expansion to produce the frictional binding force to achieve the fixing effect. One end of the screw is threaded, and the other end is tapered. There is a steel skin on the outside. Half of the iron skin cylinder has several cuts. Put them together into the holes made in the wall. Then lock the nut. The nut pulls the screw outwards and pulls the cone into the steel skin cylinder. The steel skin is round. The tube is expanded, so it is tightly fixed to the wall, and is generally used to fasten protective fences, awnings, air conditioners, etc. on cement, bricks and other materials. But its fixing is not very reliable. If the load has a large vibration, it may loosen, so it is not recommended to install ceiling fans.
