DeWalt 5-Piece Impact Socket Set

This DeWalt set contains four dual-head flip sockets and a three-inch extension bar. Each socket covers two sizes, delivering 17mm, 19mm, 21mm, 22mm, 3/4in, 13/16in, 7/8in and 15/16in from just four pieces. A blue plastic case keeps the tools organised and protected.

Upgrade from single-size sockets

The flip design removes the need to swap sockets when moving between common metric and SAE lug-nut sizes. Chrome-molybdenum steel with phosphate coating handles high impact and resists corrosion, so the set replaces a larger drawer of single-hex sockets for wheel work. The jump is worth it when speed and reduced rounding matter on the job.

Suits technicians changing wheels daily

Mechanics who service cars, light trucks and fleet vehicles gain faster size changes and secure flat-side grip. Builders needing deep-well sockets, thin-wall profiles or sizes outside the eight listed should look at dedicated single-hex sets instead.

Questions about this item

What drive size do the sockets and extension bar use?

The set uses a 1/2" drive for both the four dual-head sockets and the included 3" extension bar.

How do I attach the extension bar to the sockets?

Insert the 1/2" drive end of the 3" extension bar into the socket's drive square until the detent ball clicks, ensuring a firm connection before applying torque.

Will the phosphate coating need reapplication?

The phosphate black coating resists corrosion and wear under normal use; it does not require reapplication, though sockets should be inspected for cracks or excessive wear before each job.
