Hydrogen Embrittlement in zinc plated screws
Recently we ran into a Hydogen Embrittlement problem on a thread forming screw(#5-40). The screw is made from aluminum killed carbon steel wire. There is HE relief done at 350F for 3-5 hours directly after zinc electroplating to a thickness of 0.0002 to 0.0005. This screw mates two aluminum die cast parts. To remove all potential of HE occurring (if possible)what recommendations for alternative plating are suggested?

You should look at mechanical plating of your parts.
