🧰Koken Flat Drive Socket 4400M shallow 4300M deep 14400M impact socket

The Koken Flat Drive is one of the best sockets I've ever tested, especially for its grip torque before it slips from the nut/bolt. It works well on slightly damaged or rounded nuts. Its flat drive socket design keeps the socket's contact point slightly away from the nut/bolt corner, preventing the nut or bolt from collapsing while applying high torque, and preventing the nut and bolt from breaking. How does it compare to Ingco, KTC, Tone, Bullock, Jetech, Snap On, and Hazet? The Koken Flat Drive is one of the socket bits I've tested on this channel, especially for its exceptional grip torque before the socket grips the bolt head. Even on slightly rounded nuts, the Koken Flat Drive still provides a good grip for loosening/turning nuts. The Flat Drive design of the socket bit provides a contact point away from the edges or corners of the nut, preventing the nut from slipping easily and also preventing damage at the corners.
