It is incorrect terminology. Embedment is said to smooth surfaces and
so result in less adhesion and loss of bolt tension. Embedment "can
lead directly to loosening of a fastener joint and subsequent fatigue
failure." (Wikipedia)

Also known as galling. Agreed.

Newbies should understand that the pitch of the pulley bolt is even
smaller than what is found on even fine thread bolts. This increases
the tendency towards galling. IMO the conditions under which the bolt
must operate (high thermal and load variation) promote galling even
further.

Say, isn't this something like the discussion we had the last time? :-)
