The MILWAUKEE TOOL 49-66-7002 is a metric socket set covering sizes from 4 mm to 15 mm, designed for standard drive applications in professional trades. The set delivers a wide range of metric socket sizes in a single package, reducing the need to source individual sockets across common fastener sizes. At 15.59 pounds packaged and measuring 13.81 inches in length, 4.37 inches in width, and 15.59 inches in height, this is a substantial, job-site-ready set suited for electricians, HVAC technicians, plumbers, and mechanical contractors who work with metric hardware daily.
This socket set is appropriate for residential and light commercial service work where metric fasteners are standard. It covers the 4 mm to 15 mm range that appears frequently on equipment panels, motor mounts, condensing unit hardware, and plumbing fixture assemblies. Technicians who regularly encounter metric fasteners on imported equipment or newer domestic systems will find this range covers the majority of common sizes in the field.
Designed as a general-purpose metric socket set compatible with standard drive tools used across HVAC, plumbing, electrical, and mechanical service applications.
Socket sets of this type are used by licensed tradespeople across multiple disciplines. Always ensure the drive tool and socket are fully engaged before applying torque to avoid rounding fasteners. Inspect sockets for cracks or wear before each use, and retire any damaged socket from service immediately. Follow applicable trade safety practices and job-site PPE requirements when working with hand tools.
