Bolt description abbreviation decoding ZNFL,ZNNI,SMAT,CMAT,HF

[chadconway]

Anyone know what these stand for in Tesla part names of bolts? ZNFL,ZNNI,SMAT,CMAT,HF
I am guessing the Z ones are some sort of Zinc coating and HF has something to do with ferrous.
Two examples:

BOLT,HF,M10-1.5X36,[109],ZNFL,CMAT.	1461652-00-A
BOLT,HF,M10X27,STL[109],ZNNI,SMAT	1629334-00-A
