I've put a lot of Zn plated and mostly hot dip galvanized lag bolts into
trees of all varieties over the years and seen no problems except the
need to back them out a bit as the tree grew around them. A good sign I
think. When installed, I leave at least 3/8 to 1/2" slack for growth.
The arborist or mill that might prune or harvest the tree someday would
appreciate their removal when no longer needed. Instant trashing of a
saw chain.
Absolutely no copper or Cu alloys (bronze, brass) or plating should be
used. Stainless I think is ok, but rarely has been my fastener.
