F-it! Tightening Tool: What's the F-Shaped piece for?

Named for it's F-ish shape, the F-it! tool was designed to keep your mounts extra snug. Made of ridiculously F-ing strong metal, our F-it! tool provides a little extra leverage to ensure your device holders stay right where you want them.

Place the F-it! tool over the thumb nut screw and give it a gentle turn - careful, not too tight!
