Certainly Bob,
I use 1018 for most screws and then case harden them. I first turn the whole diameter to just a touch larger than I want the head diameter to be, then turn the body and file a point on the shaft. I have a large selection of dies, speciality thread pitches can be purchased here: https://www.victornet.com/productpa...vzre37gIVTRitBh2zzgSHEAAYASAAEgIbRvD_BwE

I then thread the shaft and cut the proper angle on the head, usually 60 degrees on British screws, the blank is then parted off leaving enough materiel for a slave screw slot. The new screw is the fit up and the proper indexing postion(best to stop a bit shy and final fit to get it perfect) is marked and the cut on the mill using a slotting saw. The screw can then be put back in the lathe (a shop made threaded collect shines here), cut to the correct length and domed and polished.

Lots of work in properly making a new screw but a regular occurance in my shop.
