Hey guys, I know this may be a silly question, but I can't find any screws and nut, or posts that I think would make good tention hardware for the holsters I'm making. I've been using stainless 8-32 screws and nylon insert nuts for my OWB holsters and they work ok. But can't use them for IWB. Need a screw and post or t nut combo that works good for you guys. And where can I get them. People like the holsters I've made but some say my IWB needs tention adjustment. Please help a brother out.
