Screw hexagonal partial thread UNC ZB 7/8x3

Product detailed description

The partially threaded hex head screw is designed according to American standards using the UNC (Unified National Coarse) thread profile. This screw has a diameter of 7/8 inch and a length of 3 inches, which corresponds to approximately 22.23 mm and 76.2 mm. The UNC thread is characterized by a coarser profile, which provides better resistance to loosening in applications with vibrations or dynamic loads.

The screw is made of steel and falls into the strength class Grade 5, which approximately corresponds to European class 8.8. This strength class provides high mechanical resistance, which is suitable for applications where high strength and reliability of the connection are required. The white zinc coating provides additional corrosion protection, thus extending the life of the screw in environments exposed to moisture or chemical influences.

The head shape is hexagonal, which allows for easy use of common tools, such as wrenches or sockets, for assembly and disassembly. The screw is suitable for various industrial applications, including mechanical engineering, construction and the automotive industry, where strong and durable connections are required. The DIN 931 standard, to which the screw is aligned, defines dimensions and tolerances for partially threaded screws, ensuring compatibility with other components according to this standard.
