Over the last 4 to 6 months I have been working with Kevin Lockwood on getting the two styles of nuts made. Through my supplier that I used to have the armor bolts made they sent out samples to over 25 to 30 mills with in the US and abroad and all locations turned down giving us a quote. I guess because of the detail no one was interested. In the past only two suppliers made these nuts. They are all out with no intentions to make more. That is the last I heard.
