Using the Klein Tools 3243 Hex Bar is easy. When you need to position steel members or align bolt holes, just insert the bar into the appropriate spot. The pointed end can help you get into tight spaces, and the 15 - degree angled chisel - end gives you extra leverage. Remember to wear safety gloves and goggles when using the bar. For maintenance, keep it clean and dry. If it gets dirty, you can wipe it down with a clean cloth. Store it in a dry place to prevent rusting. This bar is built to last, but handling it with care will ensure it serves you well for a long time.
