By increasing the axial force in particular, it exhibits a force that is difficult to loosen! It has a high restraining force against rotational loosening.
"UHSCREW" is a vibration-resistant screw designed to be fastened with greater axial force by changing the shape of the thread profile, making it less prone to loosening. The tightening characteristics exhibit excellent fastening strength due to the "elastic strain energy" stored in the threads from elastic deformation, resulting in superior vibration resistance. The contact surface between the male and female threads during fastening is positioned further away from the axis compared to standard small screws, which increases the torque arm of the rotational friction, thereby enhancing the restraining force against rotational loosening. 【Features】 ■ Less prone to loosening ■ Designed to be fastened with greater axial force by changing the shape of the thread profile ■ Exhibits excellent fastening strength with superior vibration resistance ■ The contact surface between the male and female threads during fastening is positioned further away from the axis compared to standard small screws, resulting in a longer torque arm of the rotational friction ■ Higher restraining force against rotational loosening *For more details, please refer to the PDF document or feel free to contact us.

The conventional left and right coaxial 30-degree trapezoidal screw shaft has been standardized for rolled threads.
The material of the left and right co-axial 30-degree trapezoidal screw "TMCR" is S20C (carbon steel for machine structures). The screw threads are formed by cold forging, resulting in a uniform thread shape. The surface of the tooth faces is smooth and exhibits work hardening, providing excellent wear resistance. The outer diameter of the screw shaft has a uniform grinding finish, making additional processing easy. Since the left and right screws are machined and formed on the same axis, they can be used for applications such as clamping devices, opening and closing devices, and simultaneous movement devices for tables, etc. 【Features】 ○ Material: S20C (carbon steel for machine structures) ○ Single pitch error: ±0.02mm ○ Cumulative pitch error: ±0.2/300mm For more details, please contact us or download the catalog.

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.*

Even without a female thread, it can be screwed in! You can screw it in while creating threads in the material yourself.
This is a type of screw that can be screwed in by creating threads in the material itself, even without a pre-existing thread. Since it only requires a pilot hole to be drilled, it reduces the number of work processes and has good workability. However, because it creates its own threads, it is not suitable for places where frequent removal is necessary. Compared to regular small screws, the pitch of the threads is coarser. 【Types of Screw Sections】 There are four types of screw sections. You can view the shapes and corresponding materials on our website. Please check the link below for more information. For further details, please feel free to contact us. ↓ ↓ ↓ ↓ ↓ ↓ ↓
