A4L-100 is a high-strength stainless steel bolt. It is available in a lineup from M16 to M27.
Based on years of experience with various types of stainless steel, SUS316L is highly regarded for its corrosion resistance and non-magnetic properties, and it is widely available in the market. We have developed bolts with a tensile strength of 1,000 N/mm² using SUS316L, along with nuts and washers designed to be used in combination with these bolts. In the development process, we focused on three points: 1. simplifying the manufacturing process, 2. preventing galling (deterioration of torque coefficient) due to metal contact between the bolt and nut when tightened with high axial force, and 3. ensuring that the nuts and washers, which must withstand the strength of the bolts, are developed from the same material.
The types of metal materials used in aircraft are very diverse, and their specifications are also varied.
The standards used for aircraft vary in their fields/features and are used selectively as needed. This catalog introduces MS, NAS, and AN.

◎What is Aluminaize α treatment… It is a processing method that involves performing low-temperature thermal diffusion treatment on the aluminum layer on the surface, allowing the aluminum layer to interdiffuse with the base material to form an alloy layer (Fe-Al intermetallic compound). ◎Why does it not seize… When the surface of the screw or the mating material reaches high temperatures, oxidation occurs, resulting in the formation of scale over 6μ. When removing the bolt, the generated scale accumulates (sticks) in the clearance between the female and male threads, causing seizing or galling. The scale from the Aluminaize α treatment is a maximum of 2μ, allowing it to roll within the clearance between the female and male threads when removing the bolt, acting as a lubricant and preventing seizing and galling. ◎Materials suitable for Aluminaize α treatment Iron, cast iron, steel, alloy steel, SUS materials, heat-resistant steel, titanium, Inconel, Hastelloy, etc. *For more details, please contact us or download the PDF.
