Half round head hexagon bolt, also known as pan head hexagon bolt, is a special type of bolt characterized by a semi-circular head and an internal hexagon shape. This type of bolt is classified according to the shape of its head and is one of the most commonly used types. In addition to cylindrical head hexagon socket screws, semi-circular head hexagon socket bolts can also be classified according to their materials, including carbon steel hexagon socket screws and stainless steel hexagon socket screws. There are various types of stainless steel hexagon socket screws, such as stainless steel SUS304 material and stainless steel SUS202 material. Half round head hexagonal bolts are widely used in situations where the bolt head needs to be hidden or embedded, as they can provide good fastening effect while maintaining surface cleanliness. In addition, this type of bolt is also suitable for situations that require a large tightening torque, as it can provide stable support and fastening force.

Standard for Half Round Head Hexagonal Bolts
The standards for half round head hexagonal bolts mainly include ISO7380 and GB70.2. The ISO7380 standard is developed by the International Organization for Standardization (ISO) and is applicable to various materials and specifications of half round head hexagon socket bolts. GB70.2 standard is a Chinese national standard applicable to domestically produced half round head hexagon socket bolts.
The specific content and application scope of ISO7380 standard
The ISO7380 standard is applicable to semi-circular hexagonal bolts made of A4-70 stainless steel, which are typically made of SUS316 material and have high corrosion resistance and strength. This standard has a wide range of applications, including but not limited to wind power fasteners, machine tool equipment, chemical equipment, etc.
The specific content and application scope of GB70.2 standard
The GB70.2 standard applies to half round head hexagon socket screws of grade 8.8 and 10.9, which are generally used in domestically produced machinery, chemical equipment, ships, etc. The surface treatment methods for screws in GB70.2 standard are diverse, including oxidation blackening, galvanizing, hot-dip galvanizing, etc.
Half round head hexagonal bolts are mainly used in machinery due to their advantages of easy fastening, disassembly, and less slip angle. They are commonly used in situations where high assembly accuracy is required and subjected to large impacts, vibrations, or alternating loads.
Half round head hexagon bolt, as a common type of bolt, plays an important role in various application scenarios due to its design characteristics. Firstly, the design of the internal hexagon allows for the use of an internal hexagon wrench for fastening and disassembling, which typically has a 90 ° corner, making it easier to tighten or disassemble and better controlling the degree of screw tightening. In addition, the round head design of the hexagon socket bolt allows for easy disassembly at an angle, especially in positions where it is difficult to use a wrench directly.
The use of semi-circular hexagonal bolts is not limited to the mechanical field, but they are also widely used in situations that require high assembly accuracy and withstand large external forces. For example, in the connection of industrial aluminum profiles, hexagonal bolts are commonly used for the connection between profiles. By drilling holes at predetermined positions and utilizing their high connection strength, the two components are tightly connected together. The use of this bolt reflects its diversity and importance in different fields.
