High-Strength M12 Stainless Steel Shoulder Bolts Corrosion-Resistant for Harsh Environments

The shoulder bolt, or shoulder screw, is a versatile fastener commonly used in applications that need controlled spacing, smooth sliding, or rotation. Here's where it's often applied:

• Machinery: Essential in equipment requiring precise alignment and movement, such as in sliding parts within transmission systems, allowing parts to move smoothly without interference from threads.
• Automotive Industry: Found in suspension, engine, and braking systems, where it connects components like bushings and bearings, enabling free rotation or sliding in moving parts.
• Electronics: Maintains the necessary spacing between circuit boards and chips, preventing electrical interference and ensuring component stability.
• Mold Manufacturing: Used in guiding and positioning mechanisms within molds to ensure stable sliding and accurate alignment, which increases precision and extends the mold's lifespan.
• Furniture Hardware: Applied in hinges and sliding rails, supporting rotational or sliding functions in furniture parts, which enhances both functionality and durability.

Basic knowledge of stainless steel: 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.

Maintenance methods:

• Cleaning: Keeping stainless steel products clean is an important part of their maintenance. You can use mild detergents and soft cloth for cleaning, avoid the use of detergents containing acidic and alkaline components, so as not to damage the surface of stainless steel.
• Stain remover: For some stubborn dirt, you can use special stainless steel stain remover for cleaning. But before using it, you should carefully read and follow the instructions in the product manual.

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 stainless steel 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).
