Released the bolt anti-rotation washer "Tsure Zero Washer."

Washer for completely preventing the simultaneous rotation of bolts, suitable for M12 to M72.

■ Completely prevents bolt rotation with the "Anti-Rotation Zero Friction Washer" Bolt sizes: Compatible with M12 to M72. International patent applied for. ■ Features of the Plarad Anti-Rotation Zero Friction Washer Prevents rotation of hex bolts. ■ Unlike washers that utilize the friction resistance of surface irregularities from knurled processing, the Zero Rotation Washer has a special structure that changes the equivalent friction diameter, ensuring that the bolt does not rotate. ■ By simply replacing standard flat washers, there is no need for cumbersome bolt anti-rotation tools or backup wrench tools, significantly reducing the time required for bolt tightening operations. Additionally, the bolt tightening task, which previously required two workers to hold the tightening tool and the anti-rotation tool, can now be done by one person, improving labor efficiency. - Strength classification: 8.8 - Material: S45C - Surface treatment: Trivalent chromate finish <For inquiries about the bolt anti-rotation zero friction washer> Please contact us for quotes or material requests.

A nut that does not loosen even after 1 million vibration tests (3D vertical and horizontal)! Compatible bolt sizes: M14 to M100.

■ Structure and Non-Loosening Principle of the Strongest Lock Nut "Bolrock Nut" 1. When the nut is subjected to vibration and attempts to loosen counterclockwise, the fine internal balls utilize a clutch mechanism to exhibit a wedging effect, preventing the nut from turning and loosening. 2. The slope angle of the internal balls is designed to be larger than the "screw lead angle," which is the angle at which the screw rises one full turn. 3. When the nut is tightened, the internal balls automatically move to the deepest part of the groove, aligning the bottom of the nut with the top of the balls, eliminating any gap between them and the floor, thus not affecting the tightening axial force. ■ Vibration Test Condition Data - Bolt Diameter: M16 - Bolt and Nut Material: SCM435 - Frequency: 100Hz - Number of Vibrations: 1,000,000 times - Simultaneous 3D vibration in both vertical and horizontal directions While competitor lock nuts loosen after 1,100 to 2,300 vibrations, the Plarad Bolrock Nut withstands 1,000,000 vibrations, proving its overwhelming vibration resistance. <About the Strongest Lock Nut: Bolrock Nut> For inquiries such as requests for quotes or materials, please contact us.

In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
