- Shoulder screws are often used where screw connections are expected to absorb lateral forces or where the position of the workpieces in relation to one another needs to be safeguarded.
- Shaft with tolerance class f9
The shoulder shank diameter differs from ISO 7379 for the following thread diameters:
- M5 = shank diameter 6 mm
- M10 = shank diameter 12 mm
- M20 = shank diameter 24 mm
Due to the geometry, these screws can only be loaded to a limited extent in the ultimate load test according to ISO 898-1 and are marked with a 0 in front of the actual strength class.
