Does anyone know of any NAS part numbers that cover metric fasteners? Specifically I'm looking for a NAS standard that covers pan head metric machine screws. Thanks for your help.

Thanks TVP. I saw those earlier, but was hoping to find a version with the standard Phillips recess. Both NA0068 and NA0089 have the offset cruciform recess. Has anyone seen any metric NAS machine screws with a standard phillips recess?
