Thule Tool (Knob to 1/4" socket)

This is a remix of my previous Thule tool that allows you to drive the Thule knobs on a ski carrier using a powered screwdriver. My previous one attached just used a hex bit which loosens over time. This version allows you to use a quarter inch socket, which I still drive with ¼" socket to hex adapter, but the attachment point clicks in and is a bit more secure.
