smaller hands

 

Here's an addendum tip...The 1/4 drive (w/flex socket) works great to remove the bolt after it's been loosened. But it doesn't always work to break it loose (requires more torque than the small diameter extension can handle). For that, I had to revert to a 3/8 drive...Once, the bolt turned freely, I used the 1/4 drive to take it the rest of the way.

 

i bought all the angled and smaller drive sets and none worked. i reverted back to the original drive i've always had, and instead, used a very large screw driver i found in the basement, and used that as a lever propped against some rigid metal bracket down there. the bolt snapped loose very easily.
