The specifications of the expansion screws, the following heavy-duty expansion anchor manufacturers Xiaobian for everyone to introduce:

The grades of expansion bolts are divided into: 45, 50, 60, 70, 80.

Expansion screw material: mainly divided into austenite A1, A2, A4,

Martensite and ferrite C1, C2, C4,

Its representation method is, for example, A2-70,

“--” indicates the bolt material and strength grade before and after, respectively. The following is the complete expansion bolt specification table.

45 steel, for important or special purpose threaded couplings, 15Cr, 20Cr, 40Cr, 15MnVB, 30CrMrSi and other alloy steel with higher mechanical properties can be selected.

Different expansion screws are used according to the actual situation of the wall. Generally, there are the following types of 6×60, 6×80, 6×120, and 6×150.

6×60: total length 60 mm, casing length 45 mm, diameter 8 mm, wall thickness 0.7 mm, surface is zinc plated; screw length 60 mm, diameter 6 mm, threaded part 35 mm, bottom rod hammer 8 mm cone Shape, the surface is chrome-plated; the outer diameter of the nut is 10 mm octagonal, the thickness is 5 mm, the surface is white zinc plated; the outer diameter of the gasket is 13 mm, the thickness is 1 mm, the inner diameter is 6 mm, and the surface is white zinc; the elastic piece is the outer diameter. 9 mm, inner diameter 6 mm, thickness 1.6 mm ring.

6×80: total length 80 mm, casing length 65 mm, diameter 8 mm, wall thickness 0.7 mm, surface is zinc plated; screw length, nut, gasket, shrapnel same as above.

6×120: total length 120mm, casing length 105mm, diameter 8mm, wall thickness 0.7 mm, surface is zinc plating; screw length, nut, gasket, shrapnel same as above.

6×150: total length 150mm, casing length 135mm, diameter 8mm, wall thickness 0.7mm, surface is zinc plating; screw length, nut, gasket, shrapnel same as above.
