I thought about spending money on this tool but I'm so glad I did. $1 per lag was worth it. If you're just replacing one stud, you can get away with other methods. If you make more than one wheel, buy this tool. I've had great luck with Lisle tools in the past. It was no different. I installed long eyelets for wheel spacers. This tool quickly processes 20 studs. Really well done. The built in bearing ensures smooth, friction free movement and you know the eyelet is fully seated. You can't get it by rinsing. If you are installing very long spade lugs you will need either an open ended nut or some large washers to act as spacers between this tool and the hub.
