annealed wire, recommended Rc, prior to heading process
(OP)
In the cold heading process, from the annealed process prior to the headed process , are there recommened Rockwell specs to use as a guide for different grades of wire used to form metal fasteners (not stainless)? If so,where can this be found?

Quality Assurance Requirements for Carbon and Alloy Steel
Wire, Rods, and Bars for Mechanical Fasteners is a good one for your needs, although it does not list hardness.

This is another area where there are some rules of thumb, but then there are so many exceptions to those rules that they are almost useless. Spend some talking to an experienced header tooling engineer and you will learn a huge amount. A lot of this information is kept in private notebooks and not given out freely...I have some tooling people here who won't show me their private 'black book' of upsetting ratios for different materials and head styles and first blow designs.
