I am starting to set up my company's Solidworks toolbox after many years fumbling around without one.

My question is, what is the best way to go about adding weld studs and weld nuts to the toolbox?  Please don't just say use normal bolts and nuts as that will not work for us.  We have many applications where the specific geometry of weld studs / nuts are needed to avoid interference issues that would be caused by using ordinary bolts and nuts.

I want these new toolbox components to behave identically to normal bolts and nuts found in the toolbox (i.e. thread display options, smart mating, etc).
