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.

We manufacture and sell various sewing machine screws.
We offer good quality products at affordable prices.
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.
