Need help identifying star tip

I found a star tip amongst a bunch of miscellaneous parts that I would like to use.  However, I can't figure out how to build it in PCDMIS.  I'm not sure if it's a prebuilt one or a custom one.  The base threads appear to be M3.  I don't know what the tips are, but they don't appear to be either M3 or M2.  I've tried pretty much every option and combination in the drop down list, but nothing seems close.  Does it look familiar to anyone or can anyone help me identify the components if it's a custom built one?
