new era slash adapters thread pattern?

I bought a set of 117mm adapters from new era. does anyone know what thread pattern they use for replacement nuts? I called and the guy said he didn;t know of any and then told me they sell them. but I am not buying that there not the same as some others. I do know they are not the same as ofna wheel nuts. but dont want to order more that won't fit.

thanks guys.
