Screw with captive washer for Cummins engines

The 3085072 screw with captive washer serves as a specialized fastener for Cummins engine assemblies. The captive design ensures the washer remains permanently attached to the screw, which simplifies the assembly process and guarantees that the correct washer is always utilized during installation. This configuration provides a secure and uniform clamping force, effectively distributing the load across the mounting surface to maintain the integrity of the connection.

This component is manufactured for use in Cummins engines found in industrial machinery and heavy equipment. The screw is engineered to meet the specific fastening requirements of engine covers, brackets, and various fuel or lubrication system components. By maintaining a consistent hold, this fastener helps secure parts against the operational stresses and vibrations typical of heavy-duty engine environments.

Fasteners of this type perform a general function by securing mating surfaces to prevent loosening, fluid leaks, or structural misalignment within a mechanical system. The inclusion of a captive washer ensures that the load is spread evenly, which is necessary for maintaining the correct torque on critical engine joints during regular maintenance and operation.
