Re: 16ga Hammer Style Hammer Screw Needed
Sorry Bill, I used a die. After threading you need to put it in a bushing that has a tapped 4-40 hole and the washer type head must be threaded in flush to the bushing for strength. If you just tried to put the 4-40 threads in a chuck you would most likely break it off trying to do the head part, I know because I have done it more than once. Also you have to turn the die around once you get it started because the die has a lead-in to start the threads and if you go all the way it will leave a land at the end with no threads. You want threads all the way.
