2. Imperial Standard / 美制标准
American standard hex nuts in Grade 2, Grade 5, Grade 8, covering all common imperial sizes for North American market applications.
Strength Grades / 强度等级
Metric Grades / 公制等级
Available in Class 6, Class 8, Class 10
Class 6: For general light-duty equipment and conventional mechanical assembly.
Class 8: Most widely used grade, balanced strength and cost, suitable for most industrial scenarios.
Class 10: High-strength grade, matched with high-tensile bolts, applied in heavy machinery and high-load equipment.
Imperial Grades / 美制等级
Available in Grade 2, Grade 5, Grade 8
Covers low, medium and high-strength requirements for American standard mechanical assemblies.
Surface Treatments / 表面处理工艺
We provide multiple anti-corrosion surface treatments to adapt to different environmental and customer requirements:
1. Zinc Plated (Electro-galvanized) 电镀锌：Cost-effective, bright and uniform surface, basic anti-rust performance for indoor and general outdoor use.
2. Zinc-Nickel Plated 镀锌镍：Excellent corrosion resistance, far superior to ordinary zinc plating, suitable for harsh working environments.
3. Geomet Coating 久美特：Non-electrolytic anti-corrosion coating, no hydrogen embrittlement, high weather resistance, meets high-standard automotive and environmental protection requirements.
4. Dacromet Coating 达克罗：Super anti-rust, heat-resistant and corrosion-resistant performance, widely used in engineering machinery, outdoor facilities and marine equipment.
5. Black Zinc Plated 镀黑锌：Also known as black electro-galvanizing, with a uniform black matte surface and beautiful appearance. It has good anti-corrosion and anti-oxidation properties, with higher ornamental value while ensuring basic rust resistance. Widely used in mechanical equipment, automotive parts and precision fastening scenarios with appearance requirements.
6. Nickel Plated 镀镍：Features a smooth, bright and uniform metallic surface with high hardness and good wear resistance. It provides excellent anti-oxidation and anti-corrosion performance, not easy to rust and discolor. Ideal for precision instruments, electronic equipment and high-end mechanical parts with strict appearance and durability requirements.
7. Chrome Plated 镀铬：Boasts ultra-high surface hardness, outstanding wear resistance, scratch resistance and glossiness. The coating is firm and stable with strong corrosion resistance. It is widely applied in high-precision equipment, automobile decoration and mechanical parts requiring high surface finish and abrasion resistance.
