Hexagon socket head screw is a common mechanical connection fastener, which consists of two parts: the head and the screw. The head is cylindrical, with a hexagonal countersunk hole inside, which is used to insert an Allen wrench to tighten or loosen screws. The screw has external threads and can be used in conjunction with parts or nuts with internal threads. By inserting an Allen wrench into the hexagonal countersunk hole at the head and applying torque to rotate the screw, the threads on the screw fit with the corresponding internal threads, generating axial tensile force to tightly connect two or more parts together, thus achieving the fixation and assembly of mechanical components. It is widely applied in fields such as mechanical manufacturing, automotive industry, electronic equipment, and furniture manufacturing. For example, in the assembly of mechanical equipment, it is used to fix various components, such as motor casings, gearboxes, etc.

Product Description
Stainless steel 310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditionsthrough 2000°F. Grade 310S is a lower carbon version, less prone to embrittlement and sensitisation in service. The highchromium and medium nickel content make these steels capable for applications in reducing sulphur atmospheres containing H2S. They are widely used in moderately carburising atmospheres, as encountered in petrochemical environments. For more severe carburising atmospheres other heat resisting alloys should be selected. Grade 310 is not recommended for frequent liquid quenching as it suffers from thermal shock. The grade is often used in cryogenic applications, due to its toughness and low magnetic permeability.

The head is cylindrical, with a hexagonal countersunk hole inside, which is used to insert an Allen wrench to tighten or loosen screws. The screw has external threads and can be used in conjunction with parts or nuts with internal threads. By inserting an Allen wrench into the hexagonal countersunk hole at the head and applying torque to rotate the screw, the threads on the screw fit with the corresponding internal threads, generating axial tensile force to tightly connect two or more parts together, thus achieving the fixation and assembly of mechanical components. It features high strength and fastening force, capable of withstanding considerable tensile and torque forces, and is suitable for applications that require reliable connections. The countersunk hole design at the head makes the surface of the screw relatively flat, beautiful and less likely to scratch other objects after installation. At the same time, it is also convenient for cleaning and maintaining the surface of the parts. It is widely applied in fields such as mechanical manufacturing, automotive industry, electronic equipment, and furniture manufacturing. For example, in the assembly of mechanical equipment, it is used to fix various components, such as motor casings, gearboxes, etc. In the assembly of automotive engines and chassis, various brackets and components are connected; In electronic products, it is used to fix components such as circuit boards and casings.
