Product Description:
1. Shoulder bolts, also known as shoulder screws, are essential fasteners that ensure stable spacing, smooth sliding, or rotational motion in many fields. Some of their most common applications include:
1. Machinery: Vital in components requiring precise alignment, such as sliding parts in transmission systems where shoulder bolts prevent interference from threads.
2. Automotive: Frequently used in suspension, engine, and braking systems to connect bushings and bearings, allowing parts to move freely.
3. Electronics: Crucial for maintaining spacing between circuit boards and chips, preventing electrical issues while stabilizing components.
4. Mold Manufacturing: Ensures smooth sliding in guiding mechanisms, improving precision and extending mold life.
5. Furniture Hardware: Applied in hinges and rails to control movement in furniture, ensuring long-lasting durability.
6. Aerospace: Used in aerospace components where high precision and stability are critical for positioning parts.
7. Industrial Automation: Shoulder bolts are used in robotics and conveyor systems to ensure alignment and smooth operation.
8. Medical Equipment: Ensures smooth movement in devices with adjustable parts, improving accuracy and longevity.
9. Tooling & Fixtures: Important in maintaining fixed alignment and spacing for precision manufacturing.
10. Construction & Heavy Equipment: Shoulder bolts provide stable movement in structural components, improving equipment performance under heavy loads.

Stainless Steel:
1, the 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.
2, stainless steel 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. When removing dirt, you should try to avoid using irritating cleaning tools to avoid scratching the stainless steel surface. After cleaning, rinse with water and dry with a clean soft cloth.
3, the use of 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. In addition, stainless steel products on the dirt can be cleaned with alcohol or vinegar, these common cleaners on stainless steel has a certain decontamination effect.

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. Austenitic stainless steel corrosion resistance comes from the formation of chromium oxide protective layer on the metal surface. When the material temperature is heated to 450 degrees -900 degrees, the structure changes, will form chromium carbide along the edge of the crystal and can not form a protective layer of chromium oxide, thus reducing the corrosion resistance, this is also known as ‘intergranular corrosion’. As a result, there are 304L and 316L, the two due to the low carbon content also reduces the intergranular corrosion. In particular, the higher susceptibility to intergranular corrosion does not mean that non-low carbon content is more susceptible to corrosion, in a highly chlorinated environment, this susceptibility is also higher.
304 stainless steel
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. 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard.
A2 stainless steel and A4 stainless steel, A2 is a class of 304 stainless steel, A4 is a class of 316 stainless steel, the main difference between the two is here, some of the fastener industry will be 302HQ and 304 referred to as: A2, 316 and 316L (C content of carbon C is less than 03% of the stainless steel, you can increase the ‘L’ logo) called A4.
What is the difference between a270 and a470 stainless steel bolts Nuts are usually used in conjunction with bolts. Hexagonal nuts are more widely used.C-grade hexagonal nuts are used in steel structures, machinery and equipment with rough surfaces and low requirements for precision.A-grade and B-grade hexagonal nuts are mainly used in machinery and equipment with smooth surfaces and high requirements for precision.
