★EASY TO USE- You only need to use a hammer to hit the removal tool onto the damaged nut, then select the 1/2 inch square drive wrench to loosen the nut counterclockwise to remove these rusted nuts.
★TIGHT GRIP AND BIT- The plum-shaped internal thread design provides excellent torque and can rotate deep-studded fasteners. The unsmooth concave wall inside is more conducive to the grabbing of the stubborn nut and easy to remove.
★ACCURATE AND DIVERSE METRIC SIZES – 4-piece larger sized nuts or bolts. And sockets work on SAE/Metric sizes – 17MM，19MM，21MM and 22MM, include a 12MM drift punch nut removal bar to easily pop a removed nut from your extraction sockets.
