Titanium spring washer
This is a general-purpose (No. 2) JIS standard product. It is said that the spring washer's tendency to expand creates a repulsive force that presses the screw head and the counterpart material together, making it difficult for the screw and nut to come loose. It is also referred to as a spring washer. It is compliant with EU-RoHS standards.
Titanium flat washer
When the hole diameter of the material being fastened is larger than that of the screw, it can stabilize the screw head. By increasing the surface area of the screw head, it enhances the contact with the material. It is also referred to as a washer or flat washer. It is compliant with EU-RoHS standards.

Reliable quality for heavy electrical equipment, vehicles, and heavy machinery! The main material is SUS304, with assembly done through welding.
We would like to introduce a case of machining carried out by Dainikuro. The "insulator base" has a diameter of φ500mm and a height of 600mm. The main material is SUS304, and it was assembled by welding. Our company has introduced not only milling and turning machines but also an iron worker (AMADA IW-45III) to improve processing efficiency. Please feel free to contact us when you need our services. 【Case Study】 ■ Diameter: φ500mm ■ Length: 600mm ■ Main Material: SUS304 ■ Assembly: Welding *For more details, please refer to the PDF document or feel free to contact us.
For preventing loosening of high-strength stainless steel!
High-strength fasteners made of stainless steel efficiently convert high input into spring action without waste, and reliably suppress loosening caused by initial settling or vibrations after fastening. They have high heat resistance and can be used in high-temperature environments of 350 to 370°C. Compared to conventional spring steel products, they can be used with confidence even in harsh environments where corrosion resistance is required.
A stress-free glasses life with smooth temple opening and closing!
The "Optical Smooth Washer" is a metal hinge washer coated with a solid lubricant to enhance sliding functionality. The opening and closing of the temples is smooth, and the effect lasts. It has a high heat resistance specification of 600°C, and brazing and plating are also possible. Due to its excellent chemical resistance, it is strong against nitric acid and hydrofluoric acid. 【Features】 ■ Stress-free and comfortable eyewear life ■ High heat resistance ■ Excellent chemical resistance ■ Complies with food hygiene standards *For more details, please refer to the PDF document or feel free to contact us.
Achieves a skirt shape that does not sag. It is reusable and can also reduce costs.
"ActiveX" is a bolt, nut, and washer that realizes high anti-loosening functionality with a simple shape, based on the concept of "absorbing the force that loosens screws." The spring effect generated by the elastic deformation of the skirt section absorbs vibrations and shocks, demonstrating its anti-loosening effect. According to the NAS3350 standard, vibration tests were conducted using JQA's high-speed screw loosening testing machine, resulting in a finding that it does not loosen for 17 minutes. 【Features】 ■ The spring effect generated by the elastic deformation of the skirt section absorbs vibrations and shocks. ■ Special shape for full contact of the seating surface. ■ Excellent reusability, allowing for cost reduction. ■ Passed vibration tests under the NAS3350 standard for 30,000 cycles (17 minutes). *For more details, please refer to the PDF document or feel free to contact us.
