Hex flange head cap screw for Cummins 6BTAA5.9-C178

The hex flange head cap screw 3070393 serves as a mechanical fastener used to secure components within the engine assembly. The integrated flange under the head distributes clamping force over a wider surface area than a standard hex screw, which eliminates the need for a separate washer and helps maintain joint integrity. This component is used in various engine applications, such as securing block components, cylinder heads, manifolds, or covers, where a uniform and secure connection is required to ensure proper engine operation.

This part is compatible with several Cummins engine models, including the 6BTAA5.9-C178, KTA38C-1050, QSM11-C335, and QSM19-C700. These engines are widely utilized in industrial cranes, construction machinery, and heavy equipment. The design of the flange screw allows it to withstand the torque, thermal fluctuations, and operational vibrations typical of diesel engine environments. Proper installation of these fasteners is necessary to prevent component loosening, which can lead to leaks, loss of compression, or misalignment of engine parts during machine operation.
