Hello Fergus, Got the picture. Here is a solution. Go to the Chapman Mfg Co
web site:
http://www.chapmanmfg.com/
On that web site you will find that one of their tools is a very clever,
short swing ratchet. Specifically this tool here:
http://www.chapmanmfg.com/aboutourtools.html
This ratchet is used by putting one of the hex drive adapters into the
ratchet. If the adapter is put into the ratchet from one side the ratchet
will rotate the adapter clockwise (in). If the adapter is put into the
ratchet from the other side the ratchet will rotate the adapter
counterclockwise (out).
You can start the hex socket drive 4-40 machine screw either by hand or by
using the adapter as a handle for the machine screw. Once the screw is
started, and there is enough friction to permit the ratchet to function as a
ratchet, you can put the adapter into the ratchet, feel the adapter into the
screw head socket, and ratchet away to tighten the machine screw.
Chapman standard kit # 4320 should get you started, but you might want to
look over some of the other kits available as well. I keep one Chapman kit
in the hangar and one Chapman kit in my pickup truck. I need to handle both
hex socket drive machine screws and Torx drive machine screws.
'OC' Baker Says: "The best investment we can make is the time and effort to
gather and understand knowledge."
PS: I keep one of these kits with me in my airplane at all times as my
airplane makes extensive use of hex socket and Torx drive screws. You may
prefer one of these kits to the Chapman kits:
