M6 titanium track nut set

IMPROVED DESIGN
Grade 5 (6AL-4V) titanium t-nut set.  Each nut is 25mm long and has M6 tapped holes.  Should fit most boards without modification.  A rectangular opening in the track that is at least 3/4" long will easily accommodate these nuts.  Boards with a very small round opening in the track may not accept these track nuts because of their length.  Please see pics for details.
