M5 M6 Stainless steel hexagon heavy Metal bolt and nut washer SUS304 SUS316 A2-70 A4

Hex bolts are widely used across various industries and products due to their simple design, high strength, and ease of installation.

A fully threaded bolt refers to a bolt where the entire shank (from head to end) is machined with threads. The primary distinction between this bolt and a standard bolt lies in the fact that the shank of a standard bolt may only feature threads in certain sections, whereas a fully threaded bolt has threads covering the entire shank.
Characteristics and Applications

High-Strength Connections: As the entire shaft of a fully threaded bolt is threaded, it provides greater connection strength and clamping force. This makes fully threaded bolts particularly suitable for applications requiring high load-bearing capacity or resistance to vibration.
Space-saving: In certain compact designs, using fully threaded bolts allows for more efficient use of space, as no additional unthreaded section is required to accommodate a nut.
Ease of Installation and Removal: Compared to standard bolts, fully threaded bolts may offer greater convenience during installation and removal, as the entire shaft is threaded, facilitating easier engagement with nuts.

• Construction Industry - Hex bolts are commonly used in structural steel connections, such as bridges, building frameworks, and scaffolding. Their ability to handle heavy loads and external forces like wind ensures stability and durability in construction projects.
• Machinery Manufacturing - In machinery and equipment assembly, hex bolts are essential for fastening mechanical parts in machinery such as lathes, heavy-duty equipment, and assembly lines. Their high strength and durability make them suitable for machines operating under vibration and heavy loads.
• Automotive and Transportation - Hex bolts are widely used in the automotive industry for securing critical parts like chassis, engines, and transmission systems. Their strength and reliability help maintain the vehicle's integrity under high-speed and heavy-duty conditions.
• Home Appliances and Electronics - Hex bolts are used to assemble and secure parts in appliances such as air conditioners, washing machines, and televisions. They provide reliable connections and ensure the overall stability of the products.
• Energy and Petrochemical Industry - Hex bolts are crucial in wind turbines, nuclear power plants, and petrochemical plants, where they are used in securing large equipment and pipeline systems. Their corrosion resistance and strength allow them to perform in harsh environments.
• Marine and Offshore Engineering - In shipbuilding and offshore platforms, hex bolts are used to secure deck fittings, hulls, and equipment. Stainless steel hex bolts, in particular, resist corrosion from seawater, ensuring the longevity of marine structures.
• Furniture Manufacturing - Hex bolts are frequently used in the assembly of furniture such as beds, tables, chairs, and cabinets. Their easy installation and firm fastening provide stability and long-term durability to household and office furniture.

• Versatility - Hex bolts are highly standardized and can be used universally in many applications. They are compatible with other fasteners such as nuts and washers, simplifying maintenance and replacement.
• Vibration Resistance - Due to their strong structure and tight threading, hex bolts offer excellent vibration resistance, making them suitable for environments with heavy vibration or shocks, ensuring a secure connection.
• Resistant to Environmental Changes - Stainless steel and galvanized hex bolts can withstand harsh outdoor environments, including exposure to marine conditions and chemicals. Their anti-corrosive and oxidation-resistant properties provide long-lasting performance.

Generally required chromium content of 18% or more, nickel content of 8% or more, because of its good corrosion resistance, heat resistance and other advantages, often used in food processing, storage and transport, or applied to agriculture, auto parts, building materials, chemical industry, etc., is the most widely used stainless steel, accounting for almost more than half of the total production of stainless steel.

316 stainless steel generally require chromium content of more than 16%, nickel content of more than 10%, molybdenum content of more than 2%, nickel and molybdenum, the two alloying elements of the proportion of the enhancement, so that it has a better resistance to (acid) corrosion, welding performance, and so on, and therefore have a higher price, in the medical and surgical, fine industrial components, etc. to play a greater use.
