Fasteners technology is an area  that often requires special knowledge about
friction and joint design (e.g.  Coefficient of Friction and/or
Torque-Tension).  We know this area well and  have R&D capability to support special needs.
Simply using stainless  steel is a response that ignores cost, friction,
galvanic corrosion and  availability issues.

You may want to visit  _www.zinklad.com_ (http://www.zinklad.com)  for
detailed information about  applicators, technology and automotive OEM approvals.
This program consists  of  Approved Platers  that are audited on a quarterly
basis for  compliance to the proper protocol. These finishes are free of
hexavalent chromium.

I suspect that other suppliers of  corrosion protection coatings are also
into a certification mode to help police  whether customers are properly using
chemicals designed for RoHS compliance.
