Water Pump to Fan Stud Size?

[DeesZ]

I am looking to locally source the (four each) studs, nuts, and washers that couple the water pump to the water pump pulley and fan clutch flange. I have searched the archives and come up with no results (hard to believe). The car is a 05/1972 manufacture. The parts manual calls for the following:

Studs # 08226-61410 - stud M6 coupling to water pump

Nuts # 08911-10610 - nut - hex M6

Washers # 08915-13601 - washer-spring M6

Must I pick these up from Nissan, or are there good substitutes available out there aftermarket? My guys at NAPA drew a total blank when they looked it up. They are usually pretty helpful with finding stuff, and I find it hard to believe that these are not readily available.

Please let me know what suggestions you have for finding suitable replacements (or upgrade if there is such a thing). I hesitate to re-use the old ones as they have been in/out more than once already and I don't like the looks of them any longer.

I bought a set at a local parts house from the Dorman hardware bins. I remember that they were 6mm, but can't recall the thread pitch. It was pretty standard, though.
