how to calculate tensile strength of bolt.

Property Class is a designation system which is used to defines the strength of metric fasteners i.e Bolts nuts as per ISO898- part 1. The metric fasteners are designated by a symbol comprised of 2 numbers, separated by a decimal. For example 4.6 and 8.8. The property class is normally stamped on the head of the bolt.
The first digit of bolt grade represents (1/100) th part of the nominal tensile strength or proof load stress in mega pascals. For example, a bolt with property class 4.6 have nominal tensile strength equal to 4 x 100 = 400 MPa.
