Hi, is it ok to use m5 allen key bolt instead of the pan head type described in j442 ? " Use pan head (or smaller head diameter) style screw of size M5."
The allen key bolt has a smaller head than a pan head.
The heads height is not defined in the spec. Is it then ok to use the cylindrical bolts that I linked to as long as the diameter is smaller than a typical pan head and its not leaving an excessive shade ? I think the hex or torx is muche more user friendly as you say.
