Main Features
1. Thickened Design
– Thickness is approximately 30% to 50% greater than that of standard hex nuts (such as GB/T 6170), providing a larger load-bearing area and thread contact length.
– Common specifications include GB/T 6175 (Chinese Standard) and ASME B18.2.2 (American Standard for Heavy Nuts).
2. High Strength and Durability
– Suitable for high-load or vibration environments, such as steel bridges and heavy machinery.
– Often used with high-strength bolts (such as Grade 8.8 and Grade 10.9).
3. Surface Treatment
– Available options include galvanizing, black plating, and Dacromet coating for improved corrosion resistance.
4. Across-Flat Dimensions
– Same as standard hexagonal nuts (e.g., M12 nuts have a 19mm across-flat dimension), but with a greater height.
