Can anyone tell me what is the name of the bolts that have a stud on the top of them and where to buy them. They are kind of like all thread with a nut in the middle. I can think of several different places they are used on engines but not a specific size or location. Maybe I'm whizzing against the wind and they're special application only.
I checked MSC, Aircraft Spruce and several nut and bolt sites, didn't find anything.
Appreciate any help.
