It is much faster to spin on nuts with a little knob than using most any wrench.
Using just a socket will usually result in sticking due to coarse threads or even small amounts of junk in the threads or small burrs.
This little tool will allow you to spin on nuts fast.
It also will do most of the turning in close access areas where the ratchet is moved rapidly in short strokes.
Easy to make and use.
I made mine with a new rotary broaching tool that I just finished but you could use other methods such as
using allthread for the knurled knob attachment and then just tapping out the knurled knob to the thread size on the allthread.
The thread of the allthread would be removed for the part that will engage the socket.
For mine I used some key stock for the 1/4 inch one and then just milled down some 3/8 cold rolled to fit in the 1/4" broached hole in the knob.
