Hexagon Flange Head Cap Screw
Cummins®

The Hexagon Flange Head Cap Screw, part number 3089016, manufactured by Cummins, is a critical component for commercial trucks. This screw ensures the integrity of various truck components and systems by providing a reliable fastening solution.

Basic Concepts

The Hexagon Flange Head Cap Screw features a hexagonal head and a flanged design. The hexagonal head allows for efficient torque application using standard tools, facilitating easy installation and removal. The flange at the base of the head distributes the load more evenly across the surface it contacts, reducing the risk of damage to the fastened material and enhancing the screw’s holding power. This design is particularly beneficial in applications where vibrations or dynamic loads are present, as it helps to prevent loosening over time ¹.

Role in Truck Operation

In truck operation, the 3089016 Hexagon Flange Head Cap Screw secures various components and systems. It is commonly used in applications requiring a strong, vibration-resistant fastening solution, including engine components, transmission systems, and chassis parts. By providing a secure and stable connection, the screw contributes to the overall reliability and safety of the truck ².

Key Features

The 3089016 Hexagon Flange Head Cap Screw is made from high-strength materials, such as alloy steel, which provides excellent resistance to wear and corrosion. It features a coarse or fine thread, depending on the specific application, allowing it to grip tightly into the material it is fastening. The flange design not only aids in load distribution but also offers additional surface area for torque application, further securing the fastening.

Benefits

Using the 3089016 Hexagon Flange Head Cap Screw offers several advantages. Its design allows for improved load distribution, which helps to prevent damage to the fastened materials. The screw’s resistance to loosening under vibration makes it ideal for use in dynamic environments, such as those found in commercial trucks. Additionally, the ease of installation and removal, thanks to its hexagonal head, enhances efficiency in maintenance and repair operations.

Troubleshooting and Maintenance

To ensure the longevity and optimal performance of the 3089016 Hexagon Flange Head Cap Screw, regular maintenance and inspection are recommended. Signs of wear, corrosion, or loosening should be addressed promptly to prevent failure. When troubleshooting, it is important to ensure that the correct torque specifications are used during installation to avoid over-tightening or under-tightening, both of which can lead to screw failure. Additionally, replacing screws that show signs of damage or excessive wear can help maintain the integrity of the fastened components.
