Hexagon socket bolts, also known as hexagon socket screws, are metal fasteners mainly used for component connections in fields such as construction, machinery, photovoltaic brackets, Bridges, and chemical equipment. According to performance, they are classified into common bolts (such as grade 4.8, Q235 material) and high-strength bolts (such as grade 8.8, 10.9, made of 45# steel or 20MnTiB material). Among them, high-strength bolts are further divided into friction type (with plate sliding as the ultimate state) and bearing type (with connection failure as the ultimate state) based on their force transmission characteristics.
Its materials include carbon steel, stainless steel (SUS304/316L), silicon bronze, etc. The surface treatments include hot-dip galvanizing, blue-white zinc electroplating and other processes to enhance the anti-corrosion performance. The thread specifications cover M4 to M100, with a length up to 500mm, and comply with international standards such as GB/T, DIN, and ISO. Anti-loosening measures include elastic washers, split pins and other methods. Ordinary bolts are suitable for temporary connections and can be reused, while high-strength bolts are mostly used for permanent connections.
- Construction Industry - Used in structural steel connections like bridges, building frameworks, and scaffolding. Their ability to handle heavy loads ensures stability and durability.
- Machinery Manufacturing - Essential for fastening mechanical parts in machinery such as lathes and heavy-duty equipment. Suitable for machines operating under vibration and heavy loads.
- Automotive and Transportation - Used for securing critical parts like chassis, engines, and transmission systems. Maintains vehicle integrity under high-speed conditions.
- Home Appliances and Electronics - Used to assemble appliances such as air conditioners and washing machines, providing reliable connections.
- Energy and Petrochemical Industry - Crucial in wind turbines, nuclear power plants, and petrochemical plants for securing large equipment and pipeline systems.
- Marine and Offshore Engineering - Used to secure deck fittings and hulls. Stainless steel hex bolts resist corrosion from seawater.
- Furniture Manufacturing - Frequently used in assembling beds, tables, and cabinets, providing stability and durability.
