The 7-Piece Flip Impact Socket Set includes ten sizes combined into five sockets and two nested adapters. The two nested adapters allow for dual drive (1/4-Inch, 1/2-Inch) capability. The sockets are designed for use with an impact driver including Klein's Impact Wrench (Cat. Nos. BAT20CW, BAT20CW1) and Impact Driver (Cat. Nos. BAT20CD, BAT20CD1). Easy-to-use flip feature allows for quick changes between sizes and reduces the number of tools in the tool bag. All sockets and adapters store in a convenient case for easy portability.
