Class 10.9 Bolt

Property class 10.9 bolts are used in mechanical engineering, construction and the erection of metal structures. The tensile strength of high-strength bolts is at least 800 MPa.

The class 10.9 bolt is made of alloy steel grade 40Kh. The chromium content of the steel improves corrosion resistance and allows the fastener to operate at high temperature for a long time. Bolts may have an electroplated zinc coating, hot-dip zinc coating or other types of coating.

The class 10.9 bolt made of 40Kh steel does not deform under pressure applied at a right angle to the fastener’s shank.

Class 10.9 bolts can be purchased on the FLOK website.
