Milwaukee Tool 49-66-6815 Impact Socket Set 17 Pc 3/8 in

Product Description

The MILWAUKEE TOOL 49-66-6815 is a 17-piece impact socket set built for use with 3/8 inch drive impact wrenches and ratchets. Each socket features a 6-point design and a black phosphate finish that resists corrosion and reduces glare in the field. Socket depths range from 0.25 inches to 0.9375 inches across the set. The 6-point geometry grips fastener flats rather than corners, reducing rounding on worn or rusted hardware. This set is sized for electricians, plumbers, HVAC technicians, and general mechanical tradespeople who need a reliable SAE impact socket range on a 3/8 inch drive platform.

This socket set covers a continuous SAE range suited to residential and light commercial service work. Included sizes are 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, and 15/16 inch sockets, plus a storage tray, for a total of 17 pieces. The set fits common fastener sizes encountered on equipment panels, flanges, conduit fittings, and mechanical assemblies across HVAC, plumbing, and electrical trades.

Installation Notes

Impact sockets are intended for use with impact tools only and should not be substituted with chrome hand-tool sockets under impact load. Always confirm the tool drive and socket drive size match before use. Inspect sockets for cracks or deformation before each use and remove any damaged sockets from service. No special codes govern socket use, but follow general shop safety practices when operating pneumatic or cordless impact tools.
