This screw is significant in heavy-duty truck applications due to its robust design and reliable performance. Cummins is renowned for producing high-quality components that enhance the durability and efficiency of heavy-duty trucks.

Basic Concepts

Hexagonal Flange Head Cap Screws are designed with a hexagonal head and a flange that provides a larger bearing surface. This design allows for easier tightening and loosening using a wrench or socket, reducing the risk of cam-out. These screws are typically made from high-strength materials such as alloy steel, which offers excellent tensile strength and resistance to wear and corrosion. In the automotive industry, they are commonly used to secure critical components that require high load-bearing capacity and resistance to vibration ¹.

Functionality and Operation

In the context of heavy-duty trucks, the Hexagonal Flange Head Cap Screw operates by securely fastening components that are subject to high stress and loads. Its design ensures that it can withstand significant forces without loosening, which is vital for maintaining the structural integrity of the truck. The flange head provides additional surface area for load distribution, enhancing the screw’s ability to hold components firmly in place.

Purpose of Part #4360070

The Cummins Hexagonal Flange Head Cap Screw part #4360070 plays a specific role in truck assemblies by ensuring that critical components remain securely fastened. This screw is often used in applications where high tensile strength and resistance to vibration are required, such as in engine mounts, transmission housings, and chassis components. Its use contributes to the overall structural integrity and performance of the truck.

Key Features

The key features of the Hexagonal Flange Head Cap Screw include its hexagonal flange head design, which allows for efficient tightening and loosening. The material properties of the screw, typically high-strength alloy steel, provide excellent tensile strength and durability. Additionally, the flange head offers a larger bearing surface, which enhances load distribution and reduces the risk of component failure under stress.

Benefits

Using the Cummins Hexagonal Flange Head Cap Screw offers several benefits. The improved load distribution provided by the flange head ensures that the screw can handle higher loads without deformation. The enhanced fastening security reduces the risk of components loosening over time, even under vibration. Furthermore, the material properties of the screw contribute to its resistance to corrosion and wear, ensuring long-term reliability.

Installation Guidelines

Proper installation of the Hexagonal Flange Head Cap Screw is crucial for optimal performance. The screw should be installed using the appropriate torque specifications to ensure it is tightened to the correct level without over-tightening, which could lead to stripping or damage. Best practices include using a torque wrench to achieve the specified torque and ensuring that the components being fastened are clean and free of debris to prevent galling or seizing.

Troubleshooting and Maintenance

Common issues with Hexagonal Flange Head Cap Screws include corrosion, stripping, and loosening. Corrosion can be addressed by applying a corrosion-resistant coating or using screws made from stainless steel. Stripping can often be prevented by using the correct torque specifications during installation. If a screw becomes loose, it should be re-tightened to the specified torque, and if it continues to loosen, it may need to be replaced. Regular inspection and maintenance can help identify and address these issues before they lead to component failure.
