Streamline Your Fastening Workflow with the Ultimate 8-in-2 Metric Quad Socket System

The Klein Tools 652MQS Impact-Rated Quad Socket Set is a professional-grade engineering breakthrough designed to consolidate eight essential metric hex sizes into just two versatile, high-performance flip sockets. Perfect for electricians, HVAC technicians, and industrial mechanics, this set utilizes a specialized spring-loaded mechanism that allows for instant, hands-free size transitions. By simply applying pressure, the smaller socket compresses out of the way to reveal the larger hex size, eliminating the need to stop and swap tools. Covering a metric range from 7mm to 14mm, this compact kit replaces a bulky traditional socket set, significantly reducing the weight and clutter in your tool bag while increasing your job site speed.

Forged from heat-treated, cold-forged steel and finished with a rugged manganese phosphate coating, these 1/4-inch drive sockets are specifically built to withstand the high-torque demands of modern impact drivers. The set includes a 6.5-inch extension shaft that serves as both a reach-extender and a convenient storage solution for both quad-sockets. Featuring industry-standard color-coded rings and deep-well geometry, these sockets provide exceptional reach for recessed bolts and extended threaded rods. Whether you are working in tight electrical panels or performing high-repetition mechanical fastening, the 652MQS provides the durability, precision, and efficiency that defines the Klein Tools professional standard.

Key Features
