Fasteners

The fasteners are products that fix two or more things together and form a kind of temporary joint. These joints can be easily disjointed, removed and it does not damage the components or the product. These fasteners are generally made of stainless steel, carbon steel and their alloys.

We provide best quality fasteners. The fasteners that we provide can be used worldwide as they are of international standards. We are one of the best and top suppliers of these fasteners in the domestic market.

There are more than 130 types of different grades of fasteners. Different types of stainless steel fasteners are designed for specific type of application and environment where it gets utilised. 304 stainless fasteners (commercial grade) and 316 Stainless Steel Fasteners are the two most commonly used. To keep things simple, some use 304 Stainless Steel fasteners, type 18-8 stainless Steel fasteners, and type A2 stainless steel fasteners interchangeably.

Different Types of Stainless Steel Fasteners

The following kind of strong stainless steel fasteners can be easily procured from us:

Grade 18-8, also known as stainless steel from the 300 series, it contains about 18 percent chromium and 8 percent nickel. The 18-8 series also has fasteners composed of grade variables with comparable chemical compositions, such as 302, 303, 304, 384, XM7, etc. The 18-8 series is non-magnetic, only being toughened by cold working, has better corrosion resistance than 400 series.

Grade 304 (18-8), contains 18% chromium, an average of 8% nickel, and  maximum of 0.8% carbon. This kind of fastener can bear typical corrosion as well as the majority of oxidising acids. As it is resistant to food, inorganic chemicals and other organic chemicals. Grade 304 Stainless Steel Fasteners perfectly suited for use in sinks, table tops, stoves, and other appliances. These fasteners are also used in food processing sectors. Besides being versatile, type 304 stainless steel fasteners offer an economical alternative to other stainless steel. It also has good toughness and hardness properties.

Grade 316 stainless steel fasteners are known to be reluctant to harsh settings. While the nickel level is raised, the carbon content is maintained at 0.8%. The distinction between Grade 304 and Grade 316 is the presence of molybdenum up to a maximum of 3%. These fasteners are austenitic, non-magnetic, and can only be toughened through cold working. This type of fastener can handle exposure to sodium, phosphoric acid, sulfuric acid, hypocrite solutions, calcium brine, and sulfate liquors. They are frequently used in the textile, chemical processing, marine, and other industries

For environments that are at high risk of corrosion, Stainless Steel Fasteners are recommended.  Stainless fasteners are prone to seizing up during installation, also known as galling unless great care is taken. While some grades are slightly magnetic, most stainless steel fasteners are less magnetic than standard steel fasteners. Stainless steel fasteners are widely known for their durable and high strength properties.
