Carbon Steel ISO 4017-2022 Hexagon head screws
Product details
Hexagon head screws have bolt thread specifications ranging from M1.6 to M64, with pitch ranging from 0.35mm to 6mm, lengths up to 300mm. The product grade is divided into A and B grades. The material is carbon steel.The surface can be galvanized, nickel-plated, chromium-plated, and also undergo other treatments such as blackening, electroplating, and non-electrolytic zinc powder coating, to improve its corrosion resistance and appearance.
Functional Characteristics
- Hexagonal design: The head of the hexagonal head bolt is designed into six equal-sided hexagonal shape, this design is not only beautiful, but more importantly, it is easy to use tools such as wrenches for rotating operation, making the fastening process more convenient and efficient.
- Increased coefficient of friction: The shape of the hexagonal head helps to increase the contact area between the bolt and the tool during tightening, thereby increasing the coefficient of friction, reducing slip-on, and ensuring that the bolt can be firmly fixed in the desired position.
ApplicationGrade 4.8 bolts are mostly made of unprocessed round steel, the specifications and models may not be accurate enough, and the appearance is rough. The installation is more convenient and the production cost is lower. It is mostly used for temporary fixing during tensile connection or installation, and occasions with low performance requirements.
