Harley Shovelhead/Evolution Handlebar Riser Stud, Without Flats (OEM #56105-84)
These studs came with flats and without flats. This is the style without flats. But both are common. Threads are straight and clean. But you will note some jaw marks in the smoothed shoulder of the stud--this is typical. And it may be the reason why the version with flats was ultimately used.
Offered is just the one stud, exactly as pictured. And two are required for an installation.
