Stainless Steel Shoulder Bolts, Step Design, 1/2”, 7/16”, 1” for
Engineering and Manufacturing Applications
Product Description:
Stainless Steel Step Bolts with a shoulder design are specialized fasteners used extensively in engineering and manufacturing applications. These bolts feature a stepped, cylindrical shoulder beneath the bolt head, providing distinct advantages over standard bolts. The shoulder acts as a bearing surface, ensuring that the load is distributed more evenly across the joint, which helps in preventing damage to the materials being fastened. This feature is particularly useful in applications where precision and strength are paramount.
Available in various sizes, such as 1/2”, 7/16”, and 1”, these bolts are made from high-quality stainless steel, which provides excellent corrosion resistance. Stainless steel is highly durable and performs well in harsh environments, making it ideal for use in industries such as construction, automotive, aerospace, and heavy machinery manufacturing. The corrosion resistance ensures that these bolts maintain their strength and appearance even in exposure to moisture, chemicals, or extreme temperatures.
The stepped design of these bolts allows them to fit into a wider range of applications where the bolt needs to hold specific components at a particular spacing or provide additional support. In particular, the shoulder enables easier alignment of components, reducing the risk of misalignment during installation. These features make stainless steel step bolts especially valuable for applications involving metal-to-metal connections, heavy-duty equipment, or structural supports.
In engineering and manufacturing environments, the use of these specialized bolts contributes to improved assembly efficiency, safety, and long-term reliability. Whether used in machinery, infrastructure, or any project requiring strong and corrosion-resistant fastening solutions, stainless steel step bolts with shoulder provide a high-performance solution that ensures longevity and precision in critical applications.
Shoulder screws (also called shoulder bolts) are versatile
fasteners that offer stable spacing, smooth sliding, and rotational
movement across numerous applications. Some common uses include:
1. Machinery: Essential for ensuring precise alignment and smooth
movement in sliding components, especially in transmission systems.
2. Automotive: Commonly found in suspension systems, engines, and
brakes, linking bushings and bearings for smooth rotation.
3. Electronics: Crucial in maintaining proper spacing between
circuit boards and chips, preventing electrical interference.
4. Mold Manufacturing: Used for guiding parts within molds,
ensuring smooth sliding and maintaining mold precision.
5. Furniture Hardware: Shoulder bolts are used in hinges and
sliding rails to control movement and increase furniture
durability.
6. Aerospace: Applied in aerospace components where high precision
and stability are necessary for positioning parts reliably.
7. Industrial Automation: Shoulder bolts support smooth and
accurate movement in robotic arms, conveyors, and automated
machinery.
8. Medical Equipment: Used in adjustable medical devices to ensure
smooth, controlled movement for improved functionality.
9. Tooling & Fixtures: Key in maintaining alignment and spacing in
manufacturing jigs and fixtures to ensure consistent precision.
10. Construction & Heavy Equipment: Shoulder bolts are used in
structural components to provide stable movement and reliability
under heavy loads.
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.
