Looking At The Different Types and Uses of Stainless Steel Fasteners

Stainless steel fasteners are fasteners that consist of stainless steel. Just like other stainless steel materials, they have at least 10% chromium. This percentage differentiates them from the regular steel materials. Stainless steel fasteners have the advantage of forestalling corrosion. Normally, these materials would need additional elements to enhance their structures. As such, it is commonplace for such fasteners to consist of metals like nickel, titanium, molybdenum and nitrogen among others.

Varieties of stainless steel fasteners

There are various kinds of stainless steel fasteners in the market. These varieties of fasteners include:

  18-8: These fasteners consist of 8% nickel and 18% chromium. They include fittings like 302HQ, 303, 305, 304, 302 and XM7. The 18-8 steel fasteners usually offer huge resistance to corrosion (400 series stainless). They are also nonmagnetic and only attain hardness through cold working.

•  316: 316 stainless steel fasteners are more suited to severe environments. They are usually non-magnetic, thermally non-hardenable and austenitic. Such fasteners boast of 0.08% carbon with a higher level of nickel. The presence of 3% molybdenum posits them as one of the strongest resistors of corrosion. As such, they can withstand corrosive attacks from calcium and sodium brines, phosphoric acid, sulphite liquors and hypochlorite solutions.

•  304 stainless steel fasteners: These are austenitic steel fasteners that are nonmagnetic and need cold working to harden. They come equipped with 18% chromium, which provides them with enough resistance to oxidation and corrosion. Also, it has 8% nickel content, which enables them to resist the negative effects of reducing chemicals.

Uses of stainless steel fasteners

Stainless steel fasteners fulfill an integral role in many sectors. For instance, the construction industry uses these fasteners to build structures that support heavy weights. Thanks to their non-corrosive abilities, they are the perfect components for constructing long-lasting structures. In the motor vehicle industry, stainless steel fasteners are important in the assembly of motor vehicles. Once again, their resistance to rust makes them the perfect candidates for assembling such outdoor elements like cars.

People can also use stainless steel fasteners to connect pieces of wood. Such fasteners include lag bolts and carriage bolts. Other fasteners like shoulder bolts are helpful when creating pivot points in machines. Their smooth top sections and threaded lower areas make them a perfect fit for this purpose. People who need to bolt applications can also rely on stainless steel fasteners for this purpose. They can also provide great holding power.

The widespread of stainless steel fasteners finds basis in their numerous advantages. Primarily, they are rust and corrosion-resistant. This means that they are strong and can withstand the rigors of the conditions that accelerate rusting. Also, these fasteners give people an easy time when cleaning. The high content of chromium gives them a lustrous surface, which is smooth and easy to clean.

Regardless of their strength, stainless steel fasteners also offer an easy time with regards to unfastening. This is due to their high melting points where they can withstand heat. This prevents fusing, which could make unfastening a major hassle.
