Special nuts were fastened to bolts of each material (M17×40, pitch 1.0)! A comparison of each material was conducted.
To compare practical seizure phenomena, we conducted seizure tests using special nuts. The special nuts are designed to prevent loosening and generate friction torque that prevents free rotation by applying strong pressure on the threads of the bolt through the internal spring action (SUS301). Generally, they are used with lubricants, but this time we applied them in a non-lubricated state for the seizure tests and compared various materials.

[Test Method] ■ Tighten the special nuts onto bolts of each material (M17×40, pitch 1.0) (screw in with a wrench and unscrew) ■ Conduct seizure evaluation *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Silicolloy is a revolutionary new material that contains a large amount of silicon (silicon) and was developed using pure domestic technology. Silicolloy is a super alloy that possesses high strength, heat resistance (high-temperature oxidation resistance), corrosion resistance, wear resistance, high hardness, and low dimensional changes during heat treatment, all in one steel. Currently, many engineers (technicians and designers) are advancing its commercialization, contributing to new product development and total cost reduction through increased longevity. There is 'Silicolloy A2', which excels in overall balance as a precipitation-hardened stainless steel, and 'Silicolloy XVI', which has the highest hardness in the world as a precipitation-hardened type. Those who require both corrosion resistance and high hardness should not miss it!
