Using the Klein Tools 32399 replacement bits is easy. First, pick the right bit for your job - either the #2 Square or 3/16' Slotted one. Then, insert it into your Klein Heavy - Duty (32557) or Ratcheting (32558) Multi - Bit Screwdriver/Nut Driver. Make sure it fits snugly before you start working. When using, apply steady pressure to avoid stripping the fastener. After use, clean the bits with a dry cloth to remove any dirt or debris. Store them in a dry place to prevent rust. If you notice any signs of wear, it might be time to replace the bits. That's all there is to it - enjoy your handy Klein replacement bits!
