When it comes to choosing high-quality socket head cap screws or socket machine bolts for your job, you need to know more than just the right dimensions; the materials from which your fastening components are made will be a significant factor in achieving the best result.
Knowing the difference between stainless steel, steel, brass, bronze, aluminum, etc. can help you make the right choice. Respectable fastening manufacturers offer different options to suit structural demands. For example, BACO socket bolts are frequently made of stainless steel, but they also carry bolts made from other materials that are frequently used in construction applications.
Finding the best option for the job takes a basic understanding of these materials. You’ll benefit from familiarizing yourself with the following choices.
Stainless Steel Bolts
Stainless steel is essentially a mix of low-carbon steel and chromium. These combinations are frequently referred to as an alloy. Due to the right combination of compounds, the material has excellent anti-corrosion properties and is still quite economical.
When it comes to industrial projects, stainless steel bolts are usually in heavy demand. Even though they aren’t as strong as regular steel in general, various treatments and finishes can address specific tradeoffs. Hardened stainless steel is stronger than regular steel, however, hardened steel is more durable than hardened stainless steel.
Overall, stainless steel is an excellent choice for projects where extra durability and corrosion resistance is required, but keep in mind that different types of stainless steel are used to make various structural bolts. Here are some common examples:
18 – 8 stainless steel means that it contains 18 percent of chromium and 8 percent of nickel. This is the most common type of stainless steel.
316 is a stainless steel grade that is highly resistant to corrosion. It can be used in salt water or applications exposed to chlorine. This stainless steel type comes with a higher price than 18-8.
If you aren’t sure what stainless steel type is the best for your project, a reputable bolt manufacturer can usually provide advice.
Steel is one of the most common materials used for fasteners. You can find bolts made out of regular steel and out of hardened steel, which is specially treated for durability. Steel can also be zinc and chrome plated.
Four grades of steel exist for bolt manufacturing needs: grades 2, 5, and 8, as well as alloy steel. Other grades may also be used but they aren’t as much of a standard for fasteners.
When purchasing steel bolts, make sure you carefully consider the grade. Steel bolts may sound like a straightforward option, but specific grades affect performance. If you aren’t sure about the grade, ask the manufacturer. The most common and economical option is grade 2. It’s used for projects when extra high durability is not an issue. Grade 8, on the other hand, is a hardened steel, which is excellent for durability purposes. Alloy steel bolts are very strong but they can be brittle.
Aluminum is not considered a high-strength material, but it still provides good durability for its weight and offers significant corrosion resistance. When aluminum is nicked or scratched, it doesn’t lose its natural ability to resist rust and oxidation.
When it comes to bolts, they are sometimes manufactured out of aluminum alloys containing such materials as zinc, copper, and iron. These metals increase aluminum’s durability and strength.
The three types of bolts above are by no means your only options, but they are considered standards in many industrial and construction applications. It’s beneficial to get more acquainted with their features and limitations in order to make a smarter investment when buying bolts.
