Hexagonal flange nuts are important fasteners with significant core advantages. Structurally, the flange design can evenly distribute pressure, reduce the risk of component damage, and minimize the possibility of loosening; Part of the nut flange has serrations, which can effectively prevent loosening in vibration environments; The rotating flange version can automatically adapt to different components and protect fragile material surfaces.

 

In terms of materials, hardened steel is suitable for high-strength connections, stainless steel has excellent corrosion resistance, and copper, aluminum alloys, etc. can also be selected for special scenarios. Rich surface treatment, common galvanizing with multiple colors for easy differentiation and corrosion prevention; Dacromet treatment has the characteristics of environmental protection, high temperature resistance, and no hydrogen embrittlement; Nickel plating and chrome plating can enhance wear resistance and decorative properties.

 

There are various specifications and models, with thread specifications covering M5-M24 and above, suitable for different sizes of bolts and installation scenarios. Widely used in various fields such as automobile manufacturing, mechanical equipment, electronic appliances, construction engineering, aerospace, etc., it ensures structural stability and normal system operation in the connection of key components in various industries.
