Core Functions and Application
Mechanical Fastening:
Cooperates with bolts/screws to provide stamping force, preventing connection loosening, and ensuring the integrity of structures and equipment.
Load Transfer:
Uniformly distributes bolt preload, bearing tensile, compressive, and shear force, suitable for both static and dynamic operating conditions.
Corrosion Protection:
The galvanized coating isolates the nut from air, moisture, and corrosive media, significantly extending sere in outdoor/moist environments.
Standardized Interchangeability:
Strictly adheres to DIN934/ISO4032 standards, featuring uniform dimensions and high thread precision to ensure global compatibility and quick.
Core Features
Material & Strength:
Main body made of high-quality carbon steel, commonly available in grades 4/0, with high tensile and yield strength to meet medium to high load requirements.
01
Surface Treatment:
electro-galvanizing (3–12μm) or hot-dip galvanized (40–85μm), capable of withstanding hundreds of hours in neutral salt spray tests, offering excellent rust resistance.
02
Geometry & Precision:
Hexagonal shape ensures uniform force distrn when using a wrench; threads are precision grade 6H for smooth engagement, preventing galling and allowing repeated assembly and disassembly.
03
Specification Coverage:
Full series from M2 to M56, suitable for various scenarios ranging from micro-assembly to heavy-duty structures.
04
Economy:
Carbon steel combined with galvanization offers high cost-effectiveness, balancing performance and cost, making it suitable for large-scale industrial applications.
05
