If you have RE joints, do yourself a favor and get one as soon as possible. I've worked with RE fasteners for years and have struggled to tighten the fasteners any way I could think of other than buying a tool. Now that I have the tool, I realize how stupid it was to get something to work. With this tool, regular adjustments become easy and effective. The only problem is that you still have to access the connection to tighten it. It's part of the joint design, not a tool.
