Default Whats Up With The Black Pins?

This is from the giveaway thread, I see the pins now have a black tint to them.

Well I couldnt go double because it would start to effect the pin that rides on it. Ive been in the machine business all my life but Im not an engineer so I hollared at a friend of mine thats a metallurgical engineer and we worked out the math for a couple of days. I didnt want to take any chances on a pin grooving again.

After hardness testing the two pins (idler pin and stock fuel pin) and other pins Ive collected that are from the aftermarket world he and I came up with what I have today. It took a while to find a heat treat facility that was willing to work with all the crazy techniques the engineer wanted but we finally found a place in Houston thats just knocking it out of the park. As far as hard........I cant give the specific number (being that its the EXACT number that the hardness needs to be to exibit perfect wear characteristics) buts its a few ticks harder than the stock pin. Not to mention these are stainless which is the only stainless pin offered on the market.......which doesnt corrode.
