What does the 12.9 grade mean?
It is a high-strength property class for alloy steel fasteners defined in ISO 898-1. It is stronger than standard-grade steel screws and is less likely to deform when tightened.
Is 4 mm long enough for a thin collar?
The 4 mm is the overall screw length. Choose a length that fully engages the threaded hole in the collar or hub, and make sure it does not protrude into the shaft bore.
