Newly developed "Struggle Power" sustaining screws for glasses New Z-SCREW
By applying a durable resin to the axis part, friction with the hinge is increased, enhancing adhesion and achieving a clamping force ratio of approximately 1.3 times compared to standard screws!
The "struggling force" refers to the resistance encountered when opening and closing the hinge of glasses. Due to wear and tear on the hinge, the struggling force may decrease, potentially leading to a decline in the comfort of wearing the glasses and causing wobbling of the temples. The "New Z-SCREW" increases friction with the hinge by applying a highly durable resin to the shaft, enhancing adhesion and achieving approximately 1.3 times the struggling force compared to standard screws. Additionally, the product lineup is designed to fit various hinge widths, making it suitable for a range of frames. *For detailed information such as product dimensions and results of struggling force measurement tests, please check the website below.*
