①,Material: a)Steel, Strength class: M3≤d≤M39: 5.6,8.8,10.9;d > M39: subject to agreement. Standard DIN EN ISO 898-1 b)Other strength class or material by arrangement ②,The ds value in M39 is 39~39.61 in the original document, which is ambiguous. According to the technical requirements, the corresponding tolerance for ds (Class A) in DIN EN ISO 4759-1 is h13. When ds=39, the tolerance range is 38.61~39.0. |
