Green Half Shaft Bolts?
 

I placed an order last week to Euro Web Parts and got 24 half shaft bolts with hex heads. 12 were green (or green coated) and 12 were just silver. I think the green ones came in the "Porsche" bag. Any idea what the difference would be (other than the color?)

Most likely the green bolts came from the same Porsche stock as the manufacturing stock. The green was to help the assembler not put the wrong bolt on the wrong car. Forget it. If a comparison of length is the same they are equal.
