M means bolt is of Metric Thread, and 20 refers to its diameter. It's cap diameter is 1.5 D (1.5D is for hexagonal bolt). Strength is determined from grade of bolt. Here grade 4.6
So ultimate strength, fu = 4 x 100 = 400 N/mm2
Yield strength, fy = 0.6 x ultimate strength = 0.6 x 400 = 240 N/mm2Last updated on May 28, 2025
