About the Klein 4-Piece Impact Socket Set, 7/16'' Hex and 1/2'' Drive Size, Steel - 660KIT3
Secure grip on diverse fasteners!
The Klein Tools 660KIT3 4-piece impact socket set, featuring the 5-in-1 mini impact socket (NRHDM) and the 3-in-1 flip impact socket (66044), is purpose-built for linemen and utility professionals who require compact, high-torque tools that deliver performance in tight work zones. The 5-in-1 mini socket includes three of the most commonly used square sizes—3/4", 1", and"—and an alignment slot specifically engineered to handle pole hardware like pole steps, J-hooks, drive hooks, and eye bolts. Its 4-1/2" compact, hollow shaft is ideal for reach arounds when accessing bolts behind the pole, improving both ergonomics and safety while working aloft.
Paired with it is the 3-in-1 flip impact socket, which combines 9/16" and 3/4" hex socket sizes in one convenient tool. Designed with a high-torque, 12-point geometry, it ensures quicker alignment and a more secure grip on both hex and square fasteners—especially important when handling eyelet-style hardware commonly found on utility structures. The integrated alignment slot adds extra functionality, giving workers a single tool for tightening or loosening fasteners without constant tool changes, especially when working with gloves on in harsh weather or high above ground level.
Both sockets are impact-rated and built from rugged steel to endure the demands of fieldwork, with a corrosion-resistant black manganese phosphate finish that enhances durability over time. Compact yet capable, this set eliminates the need to carry multiple heavy sockets, streamlining your tool belt and speeding up your workflow. Whether you’re installing hotline clamps or maintaining pole hardware, the Klein Tools 660KIT3 4-piece impact socket set helps you stay productive, efficient, and focused on the task—making it an indispensable part of any lineman’s gear.
