Fasteners are indispensable components in modern manufacturing and assembly. They are widely used in machinery, automotive, aerospace, construction, electronics, and everyday products. Their primary function is to mechanically or chemically join two or more parts securely while withstanding tension, shear, and impact forces.
As industrial demands for precision and strength increase, fasteners are no longer just simple connectors. They must also provide enhanced durability, corrosion resistance, and adaptability to diverse environments.
In this article, we will comprehensively cover material classifications, surface treatments, manufacturing processes, common applications, our equipment advantages, and certification standards, to present the true value of fasteners in modern industry.
Carbon steel is the most widely used fastener material. Depending on the carbon content, it is divided into low, medium, and high carbon steel. Low-carbon steel offers moderate strength and cost efficiency, making it suitable for general applications. Medium and high carbon steel provide higher hardness and tensile strength, making them ideal for heavy machinery and high-strength applications.
Stainless steel fasteners are known for excellent corrosion resistance and appearance. Common grades include 304, 316, and 410. Grade 304 is suitable for general use, grade 316 performs well in marine and chemical environments, while grade 410 offers wear resistance combined with strength.
Alloy steel fasteners are designed for high-strength applications. By adding chromium, nickel, molybdenum, and vanadium, they retain strength and durability even at elevated temperatures. They are commonly used in automotive engines, aerospace components, and pressure vessels.
Copper and brass fasteners are valued for excellent conductivity, corrosion resistance, and workability. Brass screws are widely used in electrical devices and precision instruments.
Titanium fasteners combine light weight, high strength, and corrosion resistance. They are widely used in aerospace, medical equipment, and premium industrial applications, particularly in harsh environments like seawater or strong acid and alkaline conditions.
Surface treatments significantly influence the durability, performance, and appearance of fasteners. Common techniques include:
Electro-galvanizing: Economical, widely used on carbon steel, offers basic rust protection.
Hot-dip galvanizing: Provides thicker coatings with superior corrosion resistance, ideal for outdoor and structural applications.
Nickel plating: Enhances hardness and wear resistance while offering decorative appeal.
Dacromet coating: An eco-friendly anti-corrosion method with excellent salt spray resistance, often used in automotive fasteners.
Phosphating: Improves friction performance and helps prevent loosening.
Anodizing: Used on aluminum fasteners to increase corrosion resistance and aesthetics.
Producing reliable fasteners requires advanced equipment and strict process control. Our production includes:
Raw material inspection – verifying hardness and chemical composition of steel, stainless steel, and alloys.
Cold heading & hot forging – ensuring accurate forming according to fastener specifications.
Thread rolling – performed by high-speed machines to guarantee precision and wear resistance.
Surface treatments – tailored plating or coating for different industries.
Quality testing – dimensional inspection, salt spray tests, tensile strength, and torque testing.
Fasteners play a vital role across industries:
Construction – bolts, expansion anchors for steel structures, bridges, and buildings.
Automotive – high-strength bolts, nuts, washers in engines, chassis, and body assembly.
Electronics & appliances – miniature screws and brass inserts in devices and computers.
Aerospace – titanium and superalloy fasteners for extreme conditions.
Energy & pipelines – flange bolts, screws, and nuts in oil, gas, and renewable energy projects.
