Standards for metric prevailing torque fasteners

[MintJulep]

Can anyone point me to metric standards for prevailing torque fasteners equivalent to:

MS-21044 or MIL-N-25027 for nylon insert nuts

and

MIL-DTL-18240 for nylon plug and strip external thread fasteners?

I can't speak to equivalency, but the only standards for these types of parts that I am aware of are the IFI 5XX series. You can search here:

ISO 7040 and 10513 are two metric standards for nylon prevailing torque nuts.
