Quantity
The Yancheng DIN934 Heavy Hex Nut is a high-strength fastening solution engineered for demanding industrial environments. Manufactured in strict accordance with DIN 934 standards, this heavy hex nut features a larger width across flats and greater thickness than standard hex nuts, providing superior bearing surface and clamp load capacity. With a nominal dimension of M20, it is ideally suited for heavy-duty bolted connections where reliability and safety are paramount.
Material & Mechanical Properties
Produced from ASTM A194 Grade 2H material, this DIN934 heavy hex nut offers exceptional mechanical performance. Grade 2H is a quenched and tempered carbon steel specification recognized worldwide for its high tensile strength, excellent resistance to thermal degradation, and remarkable pressure tolerance. It maintains structural integrity under temperatures up to 450°C (842°F) and performs reliably in high-pressure piping systems, pressure vessels, and flange connections. The material also exhibits good fatigue resistance, making it a preferred choice for critical bolting applications in oil, gas, petrochemical, and power generation sectors.

Surface Finish – Black Oxide
The black surface finish is not merely aesthetic; it is a functional black oxide coating that provides an initial layer of corrosion and rust resistance. This finish reduces galling during installation, offers mild lubricity for consistent torque-tension relationships, and enhances the nut’s service life in indoor or moderate outdoor environments. For more aggressive corrosive conditions, we recommend supplementary coatings or galvanization per project requirements.
