I don't know what you guys have in your tool box, but if you're always taking em apart and putting em together like me. Then let me suggest, you need one of these.
I cut the bend off some allen wrenches. The chuck on this locks when it's not under power. Just break em loose and run em on out. When tightening just let off when you feel the end is near, then put the final twist on with the grip. It works good and REALLY speeds things up. Just thought I would pass this along.
