China China Suppliers Factory High-Strength Hex Socket Bolt with Cylindrical Head & Internal Hex Drive for Durable Performance Manufacturers, Products
Product Description
Product Application
Widely applied in mechanical equipment assembly, construction engineering, furniture manufacturing, automotive accessories, ship repair and precision instrument installation scenarios.
Suitable for fastening metal parts, structural modules, thin plates and precision components, especially ideal for narrow spaces where standard wrenches cannot operate.
Compatible with standard hex socket wrenches, nuts and washers, fitting standard mounting holes to meet industrial and civilian high-precision fastening needs.
Adaptable to indoor conventional environments and general outdoor non-corrosive scenes, suitable for daily mechanical and construction fastening work.
Perfect for equipment maintenance, engineering renovation and product assembly, providing reliable fastening support for various precision and heavy-duty projects.
Material & Processing Features
Manufactured from high-grade carbon steel with quenching and tempering treatment, featuring high hardness, strong tensile strength and stable mechanical properties.
Adopts precision cold heading and thread rolling process, with smooth cylindrical head, neat uniform threads and strict dimensional tolerance control.
Internal hexagonal drive design ensures non-slip operation, uniform stress during tightening, and avoids damage to the bolt head during installation.
Integrated molding structure enhances overall strength, with high tensile and shear resistance, not easy to deform or break under heavy load.
Surface anti-rust treatment (galvanizing/blackening) improves wear resistance and oxidation resistance, prolonging service life in daily use.
Core Product Benefits
Internal hexagonal design saves installation space, suitable for concealed and precision fastening, with neat appearance after assembly.
