Will the Type QH and Type STH fuse links work in all cutouts with arc shortening rods?

Removable head fuse links will work only if the arc shortening rod has 1/4 - 28UNF threads with minimum thread depth of 3/8". Some arc shortening rods in cutouts used in the international market have threads with metric dimensions so this is an area of possible application concern.
