DIN EN ISO 898-1 DIN EN 20898-2 Strength Values of Screws / Nuts

2021-11-24
●The property class identification for standard steel screws consists of two figures separated by a point:
■The first figure, called the strength index, is equal to 1⁄100 of the tensile strength R-m in N/mm²
■The second fi gure, called the yield point ratio, indicates 10 times the ratio of the yield point R-e or the substitute yield point R-p 0.2 to the nominal tensile strength R-m. If the tensile strength R-m is multiplied by 1/10 of the second figure, the result is the yield point R-e.
