Irwin Tools 1837572 Impact Performance 1/4" to 3/8" Socket Adapter

This IRWIN Impact 3/8-inch Hex-To-Square Socket Adapter features impact drivers for durability and long life. A ball-retention design allows for quick-change applications, while the forged socket body on these impact socket adapters provides additional strength. A black oxide finish resists corrosion and helps increase the life of the bit. The 1/4-inch quick-change shank is designed to work with impact drivers and reduces slipping in standard drill chucks.
