Hex nut is a type of metal fastener that has six sides. Most nuts are cut in a hexagonal shape, since it seems to be the easiest shape to grasp. Nuts, in any form, are almost exclusively used to fasten a bolt to another object.
Material:
*Stainless steel 18-8
The most common stainless steel for general hardware use
*Zinc plated steel
A low carbon steel for general use. Zinc plated for moderate corrosion resistance.
*Zinc plated class 8.8 steel
A tempered medium carbon steel. Class 8.8 is hardened and strengthened, but not as strong as class 10.9. It is commonly found in automotive applications. Class 8.8 is similar to grade 5. Zinc plated for moderate corrosion resistance.
*Zinc plated class 10.9 steel
A tempered medium carbon steel. Class 10.9 is stranger than class 8.8, and is commonly found in high strength automotive applications. Class 10.9 is similar to grade 8. Zinc plated for moderate corrosion resistance.
*Chrome plated class 8.8 steel
