The Ko-ken 12300G series consists of premium 1/4″ square-drive deep impact sockets featuring an integrated sliding magnet . Designed specifically for professional impact wrenches and tight spaces, these sockets secure fasteners via an internal magnet that pushes back as the bolt head enters, making them ideal for automotive and assembly applications.
