Features and Benefits: Forged from the finest chrome molybdenum alloy steel - the best choice for strength and durability Radius corner design - to extend the life of fasteners The design drives the side of the fastener instead of the corner Provides increased strength, but also avoids rounding of rusted or damaged fasteners Fully guaranteed No doubt, Sunex tools offer one of the most complete and toughest Impact Socket lines around. This 1" drive 30mm deep 6 point socket is designed to tackle the toughest jobs with solid durability and keeps them pounding job after job. It also features a radius corner design, causing the socket to grab the sturdy wall of the fastener instead of grabbing the corners, resulting in less wear on the fastener.
I love all Sunex creation, they are soft to use and the prices are superior . Especially Sunex 530MD 1-inch Drive Deep 6-Point Impact Socket - 30mm is fantastic just for 37.41.
