Specification

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 h8

Notice

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 pull-out test according to ISO 898-1 and are marked with a 0 in front of the actual strength class.
