Bolts - Small M6 x 25 Flanged engine casing bolts , where can I buy?

[rocketman1]

Many bikes have Zinc plated round FLANGED head bolts, ( not hexagonal head) or some call them machine screws, either rebated for Allen keys or Torx tools, to hold on engine casings etc.
Does any one know where I can buy a good selection of these in NZ
Not sure I have the description above corrected , I'm sure to be corrected, but I'm sure you know what I mean
