ユニオン精密 List of Products and Services

We would like to introduce our "Insulated SCREW" that we handle. Achieving insulation with iron products. Compared to regular surface treatments, insulated products do not conduct electricity. If you can provide the materials you use, we will also consider conducting conductivity tests in a tightened state. Additionally, please feel free to consult us about processing for parts other than screws. 【Examples of Effects of Electricity (Partial)】 ■ Distortion of sound due to noise ■ Electromagnetic interference (EMI) ■ Malfunctions caused by static electricity ■ Equipment damage due to voltage spikes ■ Battery degradation *For more details, please download the PDF or feel free to contact us.

• Parts and Materials

"UHSCREW" is a vibration-resistant screw designed to be less prone to loosening by changing the shape of the thread profile, allowing for fastening with greater axial force. 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 rotational friction, thereby enhancing the restraining force against rotational loosening. 【Features】 ■ Less prone to loosening ■ Designed to allow fastening 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 from the axis compared to standard small screws, increasing the torque arm of rotational friction ■ Higher restraining force against rotational loosening *For more details, please refer to the PDF document or feel free to contact us.
