Screw hexagonal partial thread UNC ZB 7/16x3

Product detailed description

The partially threaded hexagonal head screw is manufactured in accordance with the American UNC (Unified National Coarse) standards, which means that it has a coarse thread profile that is suitable for applications requiring higher tensile strength and vibration resistance. The screw diameter is 7/16 inch and its total length is 3 inches, which corresponds to approximately 11.11 mm and 76.2 mm.

This screw is made of steel and belongs to the strength class Grade 5, which is equivalent to the European class 8.8. This means that it has a minimum yield strength of approximately 640 MPa and a minimum tensile strength of approximately 800 MPa. These properties make it suitable for use in structures where high strength and reliability of the connection are required.

The surface treatment of the screw is white zinc plating, which provides protection against corrosion and increases its resistance to external influences. This treatment is suitable for applications in environments with mild to moderate corrosive loads.

The screw is designed according to DIN 931, which specifies screws with partial thread and hexagonal head. This standard is internationally recognized and ensures compatibility with other components within engineering and construction applications. The screw is ideal for use in industrial and construction structures where high strength and reliability of connections are required.
