Stainless Steel Full Thread Hexagon Socket Bolt Cylindrical Head Hexagon Socket Screw

High strength hexagonal bolts are a type of mechanical component.
Its head is in the shape of an inner hexagon, which is convenient for installation and disassembly using an inner hexagon wrench and can be flexibly operated in limited space. High strength refers to the material and performance of bolts, which are generally made of high-strength alloy steel and undergo special heat treatment processes, resulting in much higher strength than ordinary bolts.
Its strength grade is usually represented by numbers, such as grade 12.9, where the preceding number represents tensile strength and 12 indicates that the minimum tensile strength is around 1200MPa; The number after the decimal point represents the ratio of yield strength to tensile strength, and 9 indicates that the yield strength is about 90% of the tensile strength. Widely used in fields such as construction, machinery, and automobiles, it plays an important role in connecting the cylinder body of automobile engines and the steel structure of large bridges. It can withstand large tensile and shear forces, ensuring the fastening and safety of connections.
