High Tensile Class 5.8 Heavy Hex Bolts, Threaded Rod and Alloy Steel Grade 5.8 Stud Bolt manufacturer in India

The international organization for standardization defines the ISO 898 specification as the standard of the mechanical and physical properties for metric fasteners. Iso 898 Class 5.8 Steel Bolt specification states that the bolts of this standard can be wither a Low or a medium carbon steel.  The specification also states that the Iso 898 Class 5.8 Steel Bolt can be constructed from a carbon steel with additives. The Steel Bolt Grade 5.8 can be cold worked or cold hardened in order to increase its strength. Cold hardening or cold working the alloy of the Class 5.8 Bolt is by plastically deforming the alloy which results in a stronger, tougher end product. In a cold work hardened condition the size of the specification Grade 5.8 Bolt ranges between M5 up to M24.

Since the Grade 5.8 Bolt With Nut is stronger because its alloy is cold work hardened, these bolts are commonly bolts found in automotive industry application. Grade 5.8 Nut have three evenly spaced radial lines on the head. The Tensile strength for the specification Class 5.8 Steel Bolt standard is 520 Mpa and the core hardness in the Rockwell scale ranges between B82 - 95.
