The DIN439 hexagonal thin nuts are meticulously manufactured from high-quality carbon steel and undergo overall blackening anti-rust treatment. They come in a wide range of specifications and standard sizes. Compared to ordinary hexagonal nuts, they are thinner in thickness and have a more compact structure. They are specifically designed for applications with limited installation space, lightweight requirements, and thin structural designs. They feature high thread accuracy and smooth mating. They are commonly used as standard fastening components in mechanical assembly, equipment frames, and mold fixtures.
This is a hexagonal thin-type screw nut that complies with the German industrial standard DIN439 (similar to the national standard GB/T 6172). It is made of carbon steel and undergoes blackening (oxidation) surface treatment. Its features include a relatively low height, excellent mechanical strength and anti-oxidation wear resistance. It is suitable for narrow installation spaces and lightweight assembly requirements, has a complete range of specifications and strong versatility, and is an ideal standard matching fastening connection component for industrial machinery, equipment frames, tooling molds, etc.
