Hexagonal cylindrical head machine screws with gasket, as described by the GB70.1 standard, are a type of machine screw that features a hexagonal socket for driving and a cylindrical head with a gasket. These screws are designed to provide a secure and tight connection, with the added benefit of a gasket that can help prevent leakage or provide a seal in the connection.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Driveability: The hexagonal drive allows for precise tightening and loosening using an Allen wrench or hex key, ensuring a secure fit.

Space-Saving Design: The cylindrical head design allows the screw to sit flush or below the surface, making it suitable for applications where space is limited.

Sealing Capability: The inclusion of a gasket can provide a seal against leaks, especially in applications involving liquids or gases.

Versatility: These screws can be used in a wide range of materials, including metals, plastics, and composites.

Scope of Application

Mechanical Equipment: Used in machinery to secure components that require a flush mount or where a seal is necessary.

Automotive Applications: Can be used in automotive systems where vibrations are common, and a secure connection is essential.

Aerospace Industry: Utilized in aerospace applications for their high strength and ability to withstand extreme conditions.

Electronic Devices: Used in electronic devices to secure components and provide a sealed environment.
