[TowerTalk] Tree's and Screws

[Grant Saviers]

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.
