Fasteners comply with impending
directives
The yellow and black chromating process used in the fastener industry to protect its products against corrosion will be banned by impending EU directives.
The EU Car Recycling Directive and the Waste Electrical and Electronic Equipment (WEEE) Directive will have a drastic effect on how vehicles, their components and materials, and electrical and electronic equipment are recycled The directives also restrict or prohibit the use of certain materials

Arnold Taptite 2000 are thread forming screws which form a female thread when screwed into a preformed hole.
Both directives affect the surface coatings used on screws and fasteners, and so industry needs to discover as quickly as possible what the directives mean.
For example, the yellow and black chromating process used in the fastener industry to protect its products against corrosion will be banned from 2006 (in the electrical industry) and from 2007 (in the automotive industry).
Both surface treatments contain hexavalent chromium compounds that, if released - which could happen when they are shredded during the recycling process - are extremely toxic and carcinogenic.
So the industry needs to begin an initiative to tackle the stability and process safety of hexavalent-chrome-free processes very soon, because as from 2006/2007 all coatings must be hexavalent-chrome-free.
Remember that the R and D for the materials and components that will be used in 2006/2007 is taking place right now.
A large number of OEMs have already adopted as standard procedures the solutions developed by Arnold Umformtechnik for screws and fasteners.
