Klein Tools Insulated Box End Wrench Set is made for the kind of work where there's no room for error. Built with three-part insulation and a white wear indicator that alerts linemen when it's time to replace. Oversized handles allow for full control with Class 2 gloves, and the stepped-down design provides greater access in hard-to-reach areas. This set all packs into a heavy-duty case that's always ready for the next job.

Klein Tools is the result of one of those “happy accidents” that turn out to be revolutionary. Klein Tools famously got their start in 1857 when a linesman came to founder Matthias Klein to repair his broken pliers. Klein replaced the broken half and when the old half of the tool broke too, Klein forged a replacement for that, thus making the first Klein Linesman pliers. Since these humble beginnings, Klein Tools has grown and become one of the largest American made toolmakers and they’re a brand used by tradesmen, linesman and electricians all across America.
