DIN 6923 Hex Flange Nut

JOYEAR Metalwork 's DIN 6923 Hex Flange Nut is a high-performance fastener that integrates a flange washer with an anti-loosening structure. JOYEAR offers two types of hex flange nuts: the first features a serrated flange, which provides superior anti-loosening performance; however, because the serration specifications are closely linked to workpiece surface hardness and assembly torque, we require detailed drawings to manufacture these to your specific needs. The second type features a smooth flange; for this version, we have established standard drawings, so customers simply need to verify that the specifications meet their requirements regarding surface protection, installation space, and reusability-no additional design work is necessary.

Regarding materials, our hex flange nuts are available in steel, stainless steel, low-carbon steel, and alloy steel to suit diverse applications ranging from standard indoor environments to scenarios involving severe corrosion, high temperatures, and heavy loads. We utilize specific material grades-such as high-quality carbon structural steel (e.g., SWCH35K), stainless steel (SUS304/SUS316), low-carbon steel (e.g., 10B21), and alloy steel (e.g., 40Cr or 42CrMo)-and apply heat treatment processes strictly matched to these grades to ensure batch traceability and consistent mechanical performance. Regardless of the flange type or material selected, we offer flexible combinations of strength classes (Grade 8, 10, or 12) and thread pitches (0.75–2.5 mm); please feel free to contact us for detailed specifications and lead times.

 

 

 

 

 

JOYEAR's DIN 6923 hex flange nuts offer flexible customization options, with sizes ranging from M5 to M48 to meet diverse operational requirements. Available in strength classes 8, 10, and 12-designed to match bolts of classes 8.8, 10.9, and 12.9, respectively-they ensure secure and reliable connections. Please note that minimum order quantities vary by strength class; kindly contact us to confirm specific details. In addition to strength, thread pitch can be customized to your needs, with support for fine and coarse threads ranging from 0.75mm to 2.5mm. Fine threads are ideal for thin-walled components or precision adjustments, while coarse threads are suited for standard heavy-duty fastening. As the choice of thread pitch directly impacts locking effectiveness and resistance to loosening depending on the application, we invite you to share your assembly specifications so we can recommend the optimal solution.
