Product Review

Since 1857, the company operated by Mathias Klein and his descendants to the fifth generation, has grown and developed along with the telecommunications and electrical industries where Klein pliers first found major usages. Today, Klein Tools, Inc. represents much more than Klein pliers. The company's product line has broadened to include virtually every major type of hand tool used in construction, electronics, mining and general industry in addition to the electrical and telecommunications fields. Klein offers a lifetime warranty on material defects and workmanship for the normal life of the product. The Klein 70579 hex-key set has two key positions for extra leverage. The hex ends are square cut for a secure full-depth fit and maximum contact with the hex socket to prevent slippage and stripping of the socket. The handy set fits in your pocket or tool box easily and help eliminate the lost key problem.
