I've been a scientific instrument maker/designer/machinist/craftsman for more than 30 years. You do not want to make your own nuts and bolts, and for many reasons.

However, it's never a bad idea to have a good tool and die set. Make sure the dies are High Speed Steel and adjustable. Also, look for an additional die holder that has a guide for the diameter thread you are cutting. Dies are notorious for not starting straight. The taps are pretty straight forward.

My personal favorite type of tap, is a two fluted gun tap. They are not as easy to break.

Good cutting fluid/oil will make them last much longer. And cutting oil is the opposite of lube oil.

Thanks!
Excellent advice from all.

I’m not talking about opening up some specialty shop or whatever, just that I like to tinker. I’m not going to rebuild the suspension in my car or whatever, but if something breaks or quits my first inclination is not to buy a new one, it’s to see if it’s fixable.

Also, I’ve had times when I could not find a part. If I can manufacture a fix then that works for me!
