Carbon Steel Hex Nut Fasteners External Hex Nut Screw Cap Grade 4.8 Locking Screw

Product Advantages: Carbon steel hex nuts are one of the most common and widely used fasteners in the world. Their advantages primarily lie in mechanical properties, cost-effectiveness, versatility, and machinability. By adjusting the carbon content and heat treatment process, nuts of varying strength grades can be produced to meet a wide range of needs, from everyday furniture to heavy machinery and building structures. Carbon steel can be easily heat-treated to high strength grades such as 8.8, 10.9, and 12.9, enabling the manufacture of nuts compatible with high-performance bolts, ensuring consistent strength and reliability throughout the joint.
Product Selling Points: Common strength grades include 4, 5, 6, 8, and 10. , 12, etc. The higher the grade, the greater the tensile strength, hardness, and guaranteed load capacity. For example, grade 8 nuts are one of the most commonly used high-strength nuts in industry. Heat-treated carbon steel nuts have a high surface hardness, capable of withstanding significant pressure and friction, preventing thread deformation or wear during tightening or vibration.

Product Application: Carbon steel has excellent ductility and plasticity, making it well-suited for forming through processes such as cold heading, hot forging, and turning. Complex yet high-strength hexagonal shapes can be produced with high production efficiency. If necessary, secondary operations such as drilling and tapping can be performed relatively easily. They are primarily used in most industrial, construction, and general-purpose applications. Food machinery, chemical industry, outdoor decoration, medical appliances, etc.

The greatest advantage of carbon steel hex nuts lies in their minimal cost and maximum versatility, while ensuring sufficient strength and reliability. Their rust resistance is perfectly offset by a wide range of flexible surface treatments, making them suitable for a wide range of environments, from dry indoors to harsh outdoor environments.

Therefore, unless special requirements are for corrosion resistance, non-magnetism, or high conductivity, carbon steel hex nuts are almost always the default, preferred, and most economical and practical solution.
