Twelve Point Cap Screw
Cummins®

The Twelve Point Cap Screw, Part #206329, manufactured by Cummins, is a specialized fastener designed for use in commercial trucks. Cummins, a well-established name in the commercial truck industry, produces this part to meet the demanding requirements of heavy-duty applications. This screw is integral to various truck assemblies, ensuring secure and reliable fastening in environments where standard fasteners may fall short.

Basic Concepts of Twelve Point Cap Screws

A twelve point cap screw is a type of fastener that features a twelve-sided head, as opposed to the more common six-sided head found on standard cap screws. This design allows for a greater contact area between the screw and the driving tool, which can result in more efficient torque transfer and reduced risk of cam-out—a situation where the driving tool slips off the screw head ¹. Twelve point cap screws are commonly used in mechanical assemblies where high torque and secure fastening are required.

Purpose and Function in Truck Operation

This Cummins part plays a role in the operation and maintenance of commercial trucks by providing secure fastening in critical areas. It is often used in applications where vibrations and dynamic loads are present, such as in engine components, transmission systems, and chassis assemblies. The screw’s design helps maintain the integrity of these assemblies by ensuring that components remain firmly attached under varying operational conditions ².

Key Features

The Twelve Point Cap Screw, Part #206329, is characterized by several key features that enhance its performance and durability. Its twelve-sided head allows for more precise torque application and reduces the likelihood of cam-out. The screw is typically made from high-strength materials, such as alloy steel, to withstand the rigors of heavy-duty use. Additionally, it may feature a corrosion-resistant coating to protect against environmental factors that could compromise its integrity over time ³.

Benefits

The advantages offered by the Twelve Point Cap Screw, Part #206329, include improved torque application, which allows for more efficient and secure fastening. The reduced risk of cam-out ensures that the screw remains engaged with the driving tool, minimizing the chance of stripped heads or loose fasteners. Furthermore, the enhanced security provided by the twelve-point design contributes to the overall reliability of truck assemblies, reducing the need for frequent maintenance or replacement.

Installation Considerations

Proper installation of the Twelve Point Cap Screw, Part #206329, is vital to ensure its effectiveness and longevity. It is recommended to use the appropriate torque specifications provided by the manufacturer to avoid over-tightening or under-tightening, both of which can lead to failure. Utilizing the correct tools, such as a twelve-point socket, will facilitate a secure and damage-free installation. Additionally, it is important to ensure that mating surfaces are clean and free of debris to promote a strong and lasting connection.

Troubleshooting and Maintenance

Common issues with twelve point cap screws may include loosening due to vibrations, corrosion, or wear. Regular inspections can help identify these problems early, allowing for timely intervention. If corrosion is detected, cleaning the affected area and reapplying a protective coating can help restore the screw’s integrity. In cases where the screw has loosened, re-torquing to the manufacturer’s specifications is recommended. Routine maintenance practices, such as checking for tightness and signs of wear, can ensure the longevity and reliable performance of these fasteners.
