Using the Klein Tools 3248 Connecting Bar is quite straightforward. When you're working on positioning steel members or aligning bolt holes, simply place the bar where needed. The pointed end can be used to start the alignment process, and the 15 - degree chisel - end gives you extra leverage for a better fit. As for maintenance, keep the bar clean after each use. Wipe off any dirt or debris, and store it in a dry place to prevent rust. Avoid using the bar for tasks it's not designed for, as this could damage the hardened steel. If you notice any signs of wear or damage, it's best to replace the bar to ensure your safety and the quality of your work. Other hex bar sizes are sold separately, so you can choose the one that suits your specific needs.
