You're looking for flat head socket screws. I get them from Fastenal (they have "YFS" on them)
The "secret" is the brass nut (double female) that is inserted and affixed into the tang holes. Justin of Ranger Knives gets them from Pop's knife supply, down in Georgia. They're not listed on the web site, you have to give him a call after 4 PM, and ask him for the "brass nuts". He sent me some sized in 8/32. Telephone # 706-678-5408. Explain to him exactly what you want. He's a real good guy to deal with. :thumbup:
