Carbon Steel Shoulder Bolts M4 M6 M8 M10 M12 M16 for Structural
Projects Industrial Applications
Product Description:
Shoulder bolts, or shoulder screws, are highly effective fasteners
that provide stable spacing, smooth sliding, and rotational motion
in various industries. Some of the typical applications are:
1. Machinery: Crucial for ensuring precise alignment in sliding
parts of transmission systems, preventing interference from
threads.
2. Automotive: Commonly used in suspension, engine, and braking
systems to connect bushings and bearings, facilitating smooth
rotation and movement.
3. Electronics: Plays a key role in maintaining spacing between
circuit boards and chips, ensuring there is no electrical
interference.
4. Mold Manufacturing: Facilitates smooth sliding of parts within
molds, improving precision and extending mold lifespan.
5. Furniture Hardware: Applied in hinges and sliding rails to
control movement, ensuring long-lasting functionality and
durability.
6. Aerospace: Used in aerospace components where precision and
stability are vital for smooth part positioning and operation.
7. Industrial Automation: Shoulder bolts ensure smooth and precise
movement in systems such as robotic arms and conveyor belts.
8. Medical Equipment: Used in adjustable medical devices to allow
smooth, controlled movement, improving performance and reliability.
9. Tooling & Fixtures: Important in jigs and fixtures for
maintaining consistent alignment, ensuring high production
accuracy.
10. Construction & Heavy Equipment: Shoulder bolts provide stable
and controlled movement in structural components, increasing
reliability under heavy-duty conditions.
Applications:
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.
Steel types:
| No. | C% | Cr% | Ni % | Mo % |
| 304 | 0.07 | 17.5-19.5 | 8.0-10.5 | / |
| 316 | 0.08 | 16.0-18.0 | 10.0-14.0 | 2.00-3.00 |
| 301 | 0.15 | 16.0-18.1 | 6-8 | / |
| 310 | 0.08 | 24-26 | 19-22 | / |
| 304L | 0.03 | 18-20 | 8-12 | / |
| 316L | 0.03 | 16-18 | 10-14 | 2-3 |
| 321 | 0.08 | 17-19 | 9-12 | / |
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.
