Hot-Forged Flange Nut | DIN 6927 | 10.9 Grade

Premium Hot-Forged Nuts for High-Strength Fastening Applications

Our hot-forged nuts represent the pinnacle of fastener technology, engineered to withstand extreme mechanical stresses in critical industrial applications. Manufactured through controlled hot forging processes using premium alloy steels, these heavy-duty nuts offer superior tensile strength and fatigue resistance compared to cold-formed alternatives. Available in standard sizes from M12 to M100 and various thread specifications including metric, UNC, and UNF, our hot-forged nuts meet international standards such as ASTM A194, ASME B18.2.2, and DIN 934.

The hot forging process creates optimal grain structure that enhances mechanical properties while eliminating internal defects, making these nuts ideal for high-pressure piping systems, structural steel connections, and heavy machinery assemblies. We offer multiple material grades including carbon steel (Grade 2H/2HM), alloy steel (Grade 7/7M), and stainless steel (Grade 8/8M) with optional heat treatment to achieve hardness levels up to HRC 35. Special configurations such as heavy hex nuts, flange nuts, and coupling nuts can be customized to meet specific project requirements.

Key advantages of our hot-forged nuts include:

• Consistent material density and superior metallurgical properties
• Excellent resistance to vibration loosening
• Higher load-bearing capacity than cold-formed nuts
• Available with various surface treatments including hot-dip galvanizing and mechanical plating
• Full material traceability with mill test certificates

These industrial-grade fasteners are widely used in oil and gas pipelines, power generation equipment, bridge construction, and mining machinery where failure is not an option. Our quality assurance process includes dimensional verification, hardness testing, and proof load testing to ensure every nut meets stringent performance criteria. Custom markings and packaging options are available for OEM requirements.
