Carbon Steel Fasteners Manufacturers

Our line of carbon steel fasteners is designed to meet the high-strength connection demands of various industrial and construction applications. Known for their exceptional durability and reliability, these fasteners ensure secure, reliable fastening in a variety of harsh environments.
We offer a wide variety of products, including:
Nuts: We offer a variety of sizes, including 5/16-18 thread and 1/2-13 thread American standard nuts, as well as the popular M12 metric nut, to accommodate various bolt sizes.
Screws and Bolts: We offer universal hexagonal screws and half-thread hexagonal screws. The hexagonal design facilitates wrench installation and removal, while half-thread bolts offer a balance of strength in the connection area and smoothness in the non-connection area.
Nuts: We offer American standard flat nuts and nylon lock nuts. American standard flat nuts offer a wide contact area for better pressure distribution. Nylon lock nuts feature an internal nylon ring to prevent loosening due to vibration and provide additional security.
All fasteners are made of high-quality carbon steel and precision-machined to ensure precise dimensions and a smooth surface. They are widely used in machinery and equipment, furniture manufacturing, building structures and the automotive industry, and are your reliable connection solutions.

Why Carbon Steel Fasteners Remain the Backbone of Industrial Manufacturing

Carbon steel fasteners are widely used across machinery, construction, automotive, energy, and infrastructure sectors due to their excellent strength, fatigue resistance, and cost-effectiveness. For buyers seeking stable performance and reliable mechanical properties, carbon steel remains one of the most trusted fastener materials on the market.

As a professional manufacturer, Jiaxing Lanyue Metal Technology Co., Ltd. integrates R&D, production, and global supply. With strict ISO 9001 quality management and advanced precision manufacturing capabilities, we provide high-quality carbon steel fasteners designed for durability, stability, and long service life.

Key Advantages of Carbon Steel Fasteners

1. High Mechanical Strength

Carbon steel offers excellent tensile and yield strength, making it suitable for applications with high structural loads and strong tightening requirements.

2. Excellent Cost Performance

Compared with stainless steel or alloy fasteners, carbon steel provides strong performance at a more economical cost, delivering high value for mass-production applications.

3. Broad Application Compatibility

From heavy machinery to precision equipment assemblies, carbon steel fasteners can be heat-treated, coated, or plated to meet diverse environmental and performance requirements.

Common Types of Carbon Steel Fasteners

Fastener Type Typical Grades Main Features Common Applications
Hex Bolts Grade 4.8 / 8.8 / 10.9 High shear and tensile strength Construction, machinery, automotive
