I don't think I've done a good job of describing those tap drivers.
They do everything the nut does and more. They have an internal capture mechanism that works similar to the ball on a ratchet wrench. It holds the tap in place.
The other end of it is a regular socket driver in 1/4, 3/8, and 1/2" complete with the detent to hold them onto an extension bar.
- Their purpose is to allow you to use a tap with your socket driver system.
- You can reach deep places, you can use universal joints or wobble ends or straight if you want.
- you can use a ratchet driver, or a screw driver, or a drill with them.
- you can even put a speed wrench on them if you want!
- the long length of an extension bar makes it easier to see if the tap is square to the hole.
The set includes a driver for all the common sizes of taps. (But I do have a few really big taps that they don't fit.)
I can't imagine why anyone would force a nut onto a tap instead of using one of these.
They are a game changer.
