It is precision-forged from 40CR steel, featuring high hardness and strong pressure resistance. Its surface is smooth, making it hard to get damaged and unlikely to scratch other items. The integrated design of the arm lever effectively enhances the clamping force, and the overall structure is made of precision steel forging, which is not easy to bend or break. With one-piece forging and forming, it has high hardness and excellent toughness, endowing the fixture with extremely strong clamping force.
