Using the Klein Tools 3244 Hex Bar is easy. When you need to position steel members or align bolt holes, just insert the pointed end into the relevant spot and use the bar to apply force. The 15 - degree angled chisel - end gives you extra leverage, so you can work more efficiently. As for maintenance, after each use, wipe the bar clean with a dry cloth to prevent rust. Store it in a dry place. Be careful not to use it for tasks it's not designed for, as this could damage the bar. And always wear appropriate safety gear when using this tool.
