Shoulder screws (also called shoulder bolts) are versatile fasteners that offer stable spacing, smooth sliding, and rotational movement across numerous applications.

Shoulder bolts are extensively used in the automotive industry due to their critical role in ensuring smooth movement and proper alignment of various vehicle components. They are an integral part of suspension systems, engine components, braking systems, and even in components such as steering mechanisms and linkages.

In automotive suspension systems, shoulder bolts are used to secure bushings and bearings, allowing parts such as control arms and suspension links to move with minimal friction. This smooth movement is critical for maintaining ride quality and handling characteristics of the vehicle.

Shoulder bolts also play a significant role in engine systems. They are used in engine mounts, timing mechanisms, and other critical parts that require precise alignment and secure fastening. In engine mounts, the shoulder bolt ensures proper spacing between the engine and the frame of the vehicle.

The braking system also benefits from the use of shoulder bolts. These bolts are used to fasten brake calipers and other components, ensuring they remain aligned and secure during operation.

Stainless steel is an alloy material with corrosion resistance, and its main components are an alloy of elements such as iron, chromium and nickel. These elements can effectively resist oxidation and corrosion, so that stainless steel has a high degree of durability and aesthetics.

• Keeping stainless steel products clean is an important part of their maintenance
• Use mild detergents and soft cloth for cleaning
• Avoid the use of detergents containing acidic and alkaline components
• For stubborn dirt, use special stainless steel stain remover

201, 304, 316 are austenitic stainless steel, according to the performance of the non-magnetic, some of the performance of the weak magnetic because of the smelting of the composition of the segregation or improper heat treatment leads to the austenite in a small amount of martensite or ferrite.

304 is a general-purpose stainless steel that is widely used to make equipment and machine parts that require good all-round performance (corrosion resistance and formability). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium, more than 8% nickel content.
