Cummins®

The Twelve Point Cap Screw, Part #3094520 by Cummins, is a specialized fastener designed for use in commercial truck maintenance. Cummins, a well-established manufacturer in the industry, produces this component to meet the demanding requirements of heavy-duty applications. This screw is integral to ensuring the reliability and efficiency of truck operations.

Basic Concepts of Twelve Point Cap Screws

A Twelve Point Cap Screw is a type of fastener characterized by its hexagonal socket head, which allows for increased torque application compared to traditional hex-head screws. This design reduces the likelihood of cam-out, where the driver slips out of the fastener head during tightening. Twelve Point Cap Screws are commonly used in mechanical assemblies where high torque and secure fastening are required ¹.

Purpose of the 3094520 Twelve Point Cap Screw in Truck Operation

This Cummins part plays a significant role in the operation and maintenance of commercial trucks. It is utilized in various engine components, chassis assemblies, and other critical areas where secure and durable fastening is necessary. This screw helps maintain the integrity of mechanical connections, ensuring that parts remain firmly in place under the stress of heavy-duty use.

Key Features

The 3094520 Twelve Point Cap Screw boasts several distinctive characteristics that enhance its performance and durability. Its design includes a twelve-point socket head, which provides a more secure fit for torque tools and reduces the risk of stripping. The screw is made from high-strength materials, ensuring it can withstand the rigors of commercial truck environments. Additionally, its threading is precision-cut to ensure a tight and secure fit, contributing to the overall reliability of the assembly.

Benefits

This part offers several advantages. Its design allows for improved torque application, making it easier to achieve the necessary tension in fastening applications. The screw’s resistance to loosening ensures that connections remain secure over time, even under vibration and dynamic loads.
