Hexagonal screw with partial thread UNC ZB 1/2x4

Product detailed description

The hexagonal head screw with partial thread in inch UNC (Unified National Coarse) is designed for applications requiring strong and reliable connections according to American standards. This screw has a diameter of 1/2 inch and a length of 4 inches, which corresponds to approximately 102 mm. It is made of steel and belongs to the strength class Grade 5, which approximately corresponds to the European strength class 8.8. This class ensures high mechanical resistance and reliability in demanding conditions.

The surface treatment of the screw is made by galvanizing, which provides protection against corrosion and increases resistance to external influences. The zinc coating is white, which is typical for this type of surface treatment. The screw is designed with a partial thread, which means that part of the screw length is unthreaded, which allows for better stress distribution during assembly and increases the strength of the connection.

The standard to which the screw is manufactured is ASME B 18.2.1, which guarantees compliance with international standards for metric and inch screws. This screw is suitable for use in various industries where high strength and reliability of connections are required, such as mechanical engineering, construction and the automotive industry. The screw is compatible with the DIN 931 standard, which allows it to be used in applications where similar technical parameters are required.
