Harley Panhead/Shovelhead Swingarm Bolt  (OEM 1958-Later)

One of the hex flats has folding, but the others are square.  Machined surfaces feel smooth, and we aren't noting any distinct bearing ridges, so this one is pretty straight.  And the threads have been tested in the shop using a nut of the correct size and thread pitch, and it threaded by hand, and without drag, no problem..
