By applying a durable resin to the axis part, friction with the hinge is increased, enhancing adhesion and achieving a gripping 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 glasses and instability in the temples. The "New Z-SCREW" increases friction with the hinge by applying a highly durable resin to the shaft, enhancing adhesion and achieving a struggling force ratio of approximately 1.3 times 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 on product dimensions and results of struggling force measurement tests, please check the website below.*
Insulate iron screws! We help you create electronic devices that are not affected by static electricity or electromagnetic waves.
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.
ITS (Ideal Timber Screw) is a product made in Japan using domestic materials, aimed at simplifying construction and enhancing the fastening strength of wood.
【Overview】 Currently, there is an increasing number of buildings using timber, led by the New National Stadium. With a focus on the sustainable use of resources and wood, we have developed a screw for timber that aims to simplify construction in wood buildings primarily using CLT and to enhance the fastening strength of wood. 【Features】 - Registered as a utility model - The cylindrical body has screw threads formed by cutting, extending in the direction of the tip with the same diameter as the body - The effective screw section can be accurately determined, preventing excessive tightening during fastening - Can be constructed with a low risk of wood splitting *For further information, please download the materials from the link below or contact us directly.

![[Patented Product] Vibration-resistant screw 'UHSCREW' that is resistant to loosening.](https://image.www.ipros.com/public/product/image/4d7/2000883464/IPROS23470008253621754054.png?w=280&h=280)
"UHSCREW" is a screw designed to withstand rotational loosening by changing the shape of the thread, allowing for fastening with greater axial force.
"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.
In particular, by increasing the axial force, it exhibits a force that is difficult to loosen! It has a high restraining force against rotational loosening.
