About the Klein 6-in-1 Impact Socket Set, Steel - 660KIT2
Compact and comprehensive for any job site!
The Klein Tools 660KIT2 8-piece impact socket set combines the strength, versatility, and convenience essential for utility professionals and electrical contractors who frequently install and maintain pole hardware. The included 6-in-1 square impact socket (NRHD4) features four of the most commonly used square sizes—3/4", 13/16", 1", and 1-1/8"—consolidated into one efficient, single-ended tool. With integrated alignment slots, this socket makes it easy to drive lag bolts or eye screws without switching tools, particularly beneficial for linemen working from bucket trucks or in tight spaces where speed and accessibility matter.
Moreover, the 2-in-1 slotted impact socket set (66090) is built for professionals who need rapid size changes and a compact tool footprint. With 12 socket sizes combined into six color-coded sockets, you get quick visual size identification and fewer tools to carry. The spring-loaded, coaxial socket design enables hands-free switching between sizes, which means you can continue working with gloves on—crucial for safety and efficiency during cold weather or when handling energized lines. The 12-point design ensures solid engagement with both hex and square fasteners, minimizing slip and rounding during torque-heavy applications.
Durably built from impact-rated steel and compliant with ASME B107.2 standards, this socket set is designed for use with heavy-duty impact wrenches, including Klein’s compact models. The set also includes a 7/16" hex quick-change adapter, allowing seamless transitions between tools without wasting time. Whether you’re installing transformers, adjusting crossarms, or maintaining pole hardware, the Klein Tools 660KIT2 8-piece impact socket set equips you with the sizes you need in a space-saving, jobsite-ready package—reducing downtime and improving workflow wherever the job takes you.
