Cummins®

The Studded Flange Cap Screw, Part #3936352, manufactured by Cummins, is a specialized fastener designed for heavy-duty truck applications. Cummins, a well-established name in the automotive and heavy-duty truck industry, ensures that this component meets the rigorous demands of commercial vehicle operations. This screw is integral to maintaining the structural integrity and operational efficiency of trucks, particularly in securing flanges and other critical components.

Basic Concepts

A Studded Flange Cap Screw is a type of fastener that includes a threaded stud and a cap screw. The stud is permanently attached to one component, while the cap screw threads onto the stud to secure another component in place. This design allows for repeated assembly and disassembly without damaging the threads. In the context of heavy-duty trucks, these screws are often used to secure flanges, which are flat disks that connect two pipes or fittings.

Purpose and Role in Truck Operation

The 3936352 Studded Flange Cap Screw plays a significant role in the operation of heavy-duty trucks by securing flanges and other components. Its design ensures a robust connection that can withstand the vibrations and stresses encountered during truck operation. By maintaining secure connections, it contributes to the overall stability and reliability of the truck’s mechanical systems.

Key Features

The 3936352 Studded Flange Cap Screw boasts several key features that enhance its performance and durability. It is constructed from high-strength materials, typically alloy steel, which provides excellent resistance to wear and corrosion. The threading type is designed to ensure a tight and secure fit, while the design specifications include features such as a hex-shaped head for easy tightening with standard tools. These attributes contribute to its ability to handle significant loads and maintain stability under various operating conditions.

Benefits

Using the 3936352 Studded Flange Cap Screw offers several advantages. Its high-strength material composition and precise threading ensure improved stability and resistance to vibration, which are critical in the demanding environment of heavy-duty trucks. Additionally, its design enhances load-bearing capabilities, allowing it to secure components under substantial stress without failure. These benefits contribute to the overall reliability and longevity of the truck’s mechanical systems.

Installation Process

Proper installation of the 3936352 Studded Flange Cap Screw is vital to ensure its effectiveness and longevity. The process involves several steps: first, ensure that the stud is correctly aligned with the flange. Next, thread the cap screw onto the stud, using a torque wrench to achieve the recommended torque specification. It is important to avoid over-tightening, which can damage the threads, and under-tightening, which can lead to insecure connections. Following these best practices will help prevent common installation pitfalls.

Troubleshooting and Maintenance

Common issues with the 3936352 Studded Flange Cap Screw may include loosening due to vibration, corrosion, or wear. Regular inspection and maintenance are recommended to identify these problems early. Signs of corrosion or wear should be addressed promptly to prevent failure. Maintenance practices include periodic re-torquing to the manufacturer’s specifications and applying anti-seize compound to prevent corrosion and facilitate future disassembly.

Safety Considerations

When working with the 3936352 Studded Flange Cap Screw, several safety guidelines should be observed. Always use the appropriate personal protective equipment, such as gloves and safety glasses, to protect against injury. Ensure that the work area is clean and free of debris to prevent accidents. Follow the manufacturer’s torque specifications to avoid over-tightening, which can lead to stripped threads or component damage. Additionally, be cautious of the high-strength materials used in the screw, as they can pose a risk if mishandled.
