1 Scope and Field of Application
Covers the requirements for large series hexagon, high strength structural steel bolts in property classes 8.8 and 10.9 and in the size range M16 to M36 with short thread lengths suitable for use in both friction-type and bearing-type structural steel joints. Bolts to this standard when matched with the appropriate nuts have been designed to provide an assembly with a high level of assurance against failure by thread stripping on overtightening.
Note - Attention is drawn to the importance of ensuring that the bolts are correctly used if satisfactory results are to be obtained.
