What does 5.8 mean on a bolt?
The digits on the 5.8 bolt infer various characteristics of the bolt. The first digit in the 5.8 Steel Stud Bolt represents its ultimate tensile strength, while the second determines its ultimate yield stress. This means that the Steel Grade 5.8 Studs have 500N/mm2 as the ultimate yield strength, and the yield stress is 80% of it.
