The Hexagon Flange Head Cap Screw, identified by part number 3936996, is a component manufactured by Cummins, a well-regarded name in the automotive and heavy-duty truck industry. This screw is integral to the mechanical systems of heavy-duty trucks, ensuring secure fastening and reliable performance under demanding conditions.

Basic Concepts

A Hexagon Flange Head Cap Screw is a type of fastener characterized by its hexagonal head and a flange beneath the head. The hexagonal head allows for efficient torque application using standard tools, while the flange provides additional surface area to distribute load and prevent the screw from sinking into the material. Within a truck’s mechanical system, these screws are used to secure various components, ensuring structural integrity and proper function.

Purpose and Role in Truck Operation

This Cummins part plays a significant role in the operation of heavy-duty trucks. It is utilized in applications where secure fastening is required, such as attaching engine components, securing chassis parts, and fastening body panels. Its design ensures that critical components remain firmly in place, contributing to the overall reliability and safety of the vehicle.

Key Features

The 3936996 boasts several key features that enhance its performance. The hexagonal head design allows for easy and precise tightening using common tools. The flange beneath the head provides additional bearing surface, which helps in distributing the load and preventing the screw from pulling through the material. Additionally, the screw is made from high-quality materials, ensuring durability and resistance to corrosion, which is vital in the harsh environments often encountered by heavy-duty trucks.

Benefits

Using this part offers several benefits. Its design contributes to durability, making it suitable for long-term use in demanding applications. The flange helps prevent loosening over time, ensuring that fastened components remain secure. Additionally, the hexagonal head allows for straightforward installation and removal, enhancing maintenance efficiency.

Installation Process

Proper installation of the 3936996 is vital for optimal performance. Begin by ensuring the mating surfaces are clean and free of debris. Use a torque wrench to tighten the screw to the manufacturer’s specified torque settings to avoid over-tightening, which can lead to damage, or under-tightening, which can compromise security. It is also important to periodically check the tightness of the screw, especially in dynamic applications, to ensure continued secure fastening.

Maintenance Tips

To maintain the 3936996, regular inspections are recommended. Check for signs of corrosion, wear, or loosening. If any issues are detected, address them promptly to prevent further complications. Additionally, ensure that the screw is tightened to the correct torque specifications during routine maintenance checks. Replacement should be considered if the screw shows significant wear or damage.

Troubleshooting Common Issues

Common issues with the 3936996 may include loosening, corrosion, or damage. If loosening is detected, re-tighten the screw to the specified torque settings. In cases of corrosion, clean the affected area and consider applying a corrosion-resistant coating. If the screw is damaged, replacement is recommended to maintain the integrity of the fastened components.
