The 4007504 Plain Washer is a component manufactured by Cummins, a well-established name in the commercial truck industry. This washer plays a significant role in the maintenance and operation of commercial trucks, contributing to the efficiency and reliability of truck components.

Basic Concepts of Plain Washers

Plain washers are simple yet vital components in mechanical systems. They are typically flat, annular metal rings that serve multiple functions. Primarily, plain washers distribute the load of a threaded fastener, such as a bolt or screw, over a larger area. This helps prevent damage to the surface material and enhances the integrity of the fastening system. Additionally, plain washers can provide a degree of vibration damping, which helps maintain the stability of the fastened components ¹.

Purpose of the 4007504 Plain Washer

The 4007504 Plain Washer is specifically designed for use in commercial trucks. It plays a role in fastening systems by ensuring even load distribution across the contact surface, which is particularly important in heavy-duty applications where components are subjected to significant stress. Furthermore, this washer contributes to vibration damping, which helps in maintaining the stability and longevity of the fastened components under dynamic conditions typical of truck operation ².

Key Features

The 4007504 Plain Washer is characterized by several key features that enhance its performance and durability. It is typically made from high-quality steel, which provides the necessary strength and resilience for heavy-duty applications. The dimensions of the washer are precisely engineered to ensure optimal load distribution and compatibility with various fastening systems used in commercial trucks. Additionally, the design of the washer includes smooth surfaces that minimize friction and wear, contributing to its longevity ³.

Benefits

Using the 4007504 Plain Washer offers several benefits. It improves the security of fastenings by ensuring even load distribution, which reduces the risk of component failure.
