It is used in various applications, including securing engine components, transmission parts, and chassis assemblies. Its design ensures that critical components remain firmly attached, even under the strenuous conditions typical of heavy-duty truck operations. This screw is particularly valuable in applications where both high strength and resistance to vibration are required ².

Key Features

The 4916802 Hexagon Flange Head Cap Screw boasts several key features that enhance its performance and durability. Its hexagonal head design allows for straightforward and efficient torque application, reducing the risk of stripping or rounding during installation. The flange beneath the head provides an increased bearing surface, which helps distribute the load more evenly and reduces the stress on the fastened components. Additionally, the screw is crafted from high-quality materials that offer excellent resistance to corrosion and wear, ensuring long-lasting performance in demanding environments ³.

Benefits

This part offers several benefits that make it an ideal choice for commercial truck applications. Its design allows for improved torque application, ensuring that components are securely fastened. The flange characteristic provides resistance to loosening, which is crucial in environments where vibrations are common. Furthermore, the enhanced load distribution offered by the flange helps protect the fastened components from undue stress, prolonging their lifespan and maintaining optimal performance.

Installation Guidelines

Proper installation of the 4916802 Hexagon Flange Head Cap Screw is vital to ensure secure fastening and optimal performance. Begin by selecting the appropriate tool for torque application, ensuring it fits the hexagonal head securely. Apply the screw to the designated location, ensuring it is aligned correctly with the mating threads. Gradually increase the torque to the specified level, being cautious not to over-tighten, which could damage the screw or the fastened components. It is also advisable to use a torque wrench to achieve the precise torque specification recommended by the manufacturer.

Troubleshooting and Maintenance

Common issues with the 4916802 Hexagon Flange Head Cap Screw may include loosening or corrosion. To address loosening, ensure that the screw is properly torqued during installation and check for any signs of wear or damage to the threads. If corrosion is observed, it may be necessary to replace the screw or apply a corrosion-resistant coating. Regular maintenance, including periodic checks for tightness and signs of wear, can help prolong the screw’s lifespan and ensure continued optimal performance.
