'standard' fasteners are the usual knurled stainless socket cap screws.
I've changed my standard washer to a smaller O.D. because
they look a little nicer.
Button-Head Screws, grade 10.9 in dark flat finish, similar to black
These are similar to O.E.M. used on
later Suzukis (Bandits, GSXR, etc), and blend in with the darker engine
colors. A more subtle look -- use when you don't want the screws
to attract attention. Sorry, but I haven't been able to find any
matching black washers. You can go without, or use any of my
other washer styles.
