Are metric bolts (flat countersunk socket head screw) that have a smooth shaft at the end, available?
I need a bolt that can stick out the other side of the surface it is threaded into. The exposed portion of the bolt should be smooth, so as to be used as a bearing surface for a transverse load.
If a short turned diameter with a flat point is what you want it is called a dog point screw. Another would be a rounded point screw that has a radius on the end. A flat point (oxymoron) is a flat, small chamfered point.
Dog point is usually better due to the end mushrooming when pressure is applied, making it hard to remove the screw. This will not happen with a dog point because there is thread relief on the end.
First link is to a fastener house that shows many different types of screw points. Second link is to McMaster-Carr a good industrial supply house.
