Does anyone know where I can get 1/4, 5/16. 3/8, 1/2X26 TPI taps and dies? I am very confused about these English sizes. I thought I needed Whitworth but now it seems I need BSF. I really don't want to go metric, I just want to clean up threads. I've read on here that some businesses make a Whitworth size head for nuts and bolts but the threads are metric or some other crap that will screw up your threads and I sure don't need that kind of trouble if I need to buy nuts or bolts. So what's the word on this kind of stuff? As always any help will be greatly appreciated.
Thank you, Duane
