Fulcrum Pins Straight Slot Groove Configurable CBBD

Our Shoulder Bolt showcases a design that combines functionality and reliability. The core of its design lies in the distinct shoulder feature, which serves as a critical element for precise alignment and load distribution. The shoulder is carefully designed with a smooth surface and accurate dimensions to fit seamlessly into the corresponding boreholes in the assembled components. The transition between the shoulder and the threaded portion is engineered to minimize stress concentrations, enhancing the bolt's overall strength. The head of the shoulder bolt is designed with ergonomics in mind, allowing for easy gripping and tightening with standard tools. Available in materials such as high-grade alloy steel for maximum strength, stainless steel for corrosion resistance, or brass for specific applications requiring non-magnetic properties, our shoulder bolts are tailored to meet a wide range of environmental and mechanical demands.

Features

Our Shoulder Bolt comes with a plethora of features that set it apart in the market. Its precise shoulder dimension ensures accurate centering of components, which is crucial for the proper functioning of assemblies. The high-quality materials used guarantee excellent mechanical properties, including high tensile strength and fatigue resistance. This enables the shoulder bolt to withstand repeated loading and unloading cycles without failure. The variety of head styles, such as hex, socket, or button head, provides flexibility in installation, allowing users to choose the most suitable option based on their specific tooling and space constraints. Additionally, our shoulder bolts can be manufactured with different thread classes and finishes, such as coarse or fine threads and zinc plating for enhanced protection against rust and corrosion. The availability of various lengths and diameters further broadens its application scope, catering to diverse engineering requirements.


Advantage

The advantages of our Shoulder Bolt are manifold. Its ability to provide accurate alignment reduces the risk of misalignment-induced wear and tear on components, thereby extending the lifespan of the entire assembly. The robust construction and high-strength materials make it a reliable choice for heavy-duty applications, ensuring the integrity of the connection even under extreme conditions. The flexibility in head styles and thread options simplifies the installation process and allows for easy integration into different systems. The enhanced corrosion resistance offered by surface treatments makes it suitable for use in harsh environments, such as marine or chemical processing industries. Moreover, our commitment to quality control ensures that each shoulder bolt meets strict performance standards, providing customers with a product that they can rely on for their critical applications.


Applications

Our Shoulder Bolt is widely applied across numerous industries. In the manufacturing of industrial machinery, it is used to secure and align parts of engines, gearboxes, and other mechanical systems, ensuring smooth operation and precise movement. In the automotive sector, shoulder bolts play a vital role in assembling chassis components, engines, and interior fixtures, contributing to the overall safety and performance of vehicles. In the electronics industry, they are used for mounting and positioning circuit boards and other delicate components, providing stability and preventing vibrations. The aerospace industry also benefits from the use of our shoulder bolts for joining structural elements of aircraft, where precision and reliability are of utmost importance. Additionally, shoulder bolts find applications in the furniture, construction, and agricultural machinery industries, where they offer a secure and accurate fastening solution.


FAQ

Q: What factors should I consider when choosing a Shoulder Bolt for my application?

A: When choosing a shoulder bolt, consider factors such as the material required based on the environmental conditions (e.g., corrosion resistance for outdoor applications), the load requirements of your assembly (including tensile and shear loads), the size and fit of the mating holes, the type of head style suitable for your installation tools and space limitations, and the thread pitch and class that will provide the desired level of tightness and connection strength. Our sales team can assist you in making the right choice based on your specific application details.


Q: Can the Shoulder Bolt be reused?

A: In some cases, a shoulder bolt can be reused if it has not been damaged during removal and still meets the required specifications. However, repeated use may cause wear and tear on the threads and the shoulder, potentially affecting its performance. It is recommended to inspect the bolt carefully for any signs of damage, such as cracks, deformation, or excessive wear, before reusing it. If in doubt, it is advisable to replace the bolt with a new one to ensure the safety and reliability of the assembly.
