Can 8.8 grade bolts be galvanized?

Thread Content

Are the galvanized bolts on the market of grade 4.8 or 8.8? Some people say that 8.8 grade bolts are not galvanized?

Is there such a saying? Hot-dip galvanized bolts, grade 8.8 _ Baidu Wenku http://wenku.baidu.com/link?url=j78q3qr1zNml3VguHy1uqHGVD03Fl8HCKwbWOKI4DqHcmdWMU9i4dqvg7Ij0p_mfRfHTMQh4VzRkAk45_Sn7DYBgmukQncBz9YrHQq1UXNK

The bolt grade refers to the tensile strength and yield strength coefficients; galvanizing is used for corrosion protection, and both 4.8 grade and 8.8 grade should be suitable

It can be galvanized; it has nothing to do with the grade.

Ours are phosphated and blackened; they are not galvanized

All of them can be galvanized; 35CrMo is also suitable. The market standard is generally 4.8-grade galvanizing, at commodity grade

It can be galvanized, but galvanizing it to grade 8.8 is unnecessary, as grade 8.8 already involves a blackening treatment

Our 12.9 grade bolts are also treated with phosphating and blackening, but we have never encountered customers who required galvanizing.

What the previous SeaFriend said is correct. Bolts of any grade can be galvanized, depending on the user’s requirements.
