Stainless Steel Fasteners

Stainless steel fasteners are crucial components that connect machines, structures, and systems. They resist rust, are stronger, and last longer than standard steel fasteners. SS fasteners such as nuts, bolts, washers and screws are used in construction, automotive, and industrial applications. Nandishwar Steel is a reliable stainless steel fastener manufacturer and supplier in India, offering stainless steel nuts bolts, and other products to fulfill the needs of a variety of sectors.

What are high tensile fasteners?

High tensile fasteners are a form of joining technology used to join two or more surfaces without welding. These specialized fasteners can securely hold and join materials together, reducing manufacturing costs and potential assembly issues. The ultimate strength of the fastening is a result of the tensile strength of its components, as well as the forces produced during installation. This joining technology offers maximum holding power for even the harshest conditions, with little maintenance required. High tensile fasteners are becoming increasingly popular within industries dealing with safety and security applications, such as aerospace, medical device and military organizations.

What are the benefits of SS Screws?

Stainless steel screws offer several advantages over other types of fasteners. They provide corrosion resistance, electrical insulation, high strength and robustness, making them an ideal choice for construction and industrial use. Their high tensile strength means they can withstand heavier loads than standard fasteners and hold their shape even when exposed to vibrations or regular use. Additionally, SS screws are non-magnetic and, therefore, preferable in applications where magnetic materials can interfere with the performance of integrated circuits or critical systems. Finally, they can be heat-treated, making them a great choice for assembly jobs requiring precision threads or special diameter requirements. All these benefits make SS screws a practical pick for any project requiring secure bolts or rivets.

How to remove SS nut bolts?

Removing SS (stainless steel) nut bolts can be tricky. The best method is to heat the area with a heat gun, ensuring that the bolt and surrounding area don't get too hot. This action will help break down any surface oxidation on the ss nut bolt and make removing it easier. If an issue persists, use penetrating oil, which will assist in dissolving and flushing out rust and other corrosion from causing an issue when you try to loosen and remove the nut or bolt itself. Finally, it's recommended to use a pair of locking pliers or vise grips to grip onto either side of the bolt head and twist counterclockwise until it breaks loose. If all else fails, consult a professional for help with large-scale projects.


Which Stainless Steel Grades are Best for Fasteners?

All stainless fasteners resist corrosion but the grade decide their strength, cost, and performance. Choosing the right grade depend on where and how the fastener will be used.

The most common grade is 304 stainless steel. It’s affordable, strong, and used in general projects like piping, kitchen gear, and handrails. This grade gives a good mix of cost and durability.

316 stainless steel is the better option for harsher settings. It has higher resistance to saltwater and chemicals, making it ideal for marine, coastal and chemical industries. It costs more but delivers longer life in tough conditions.

Grades like 410 and 420 stainless steel belong to the 400 series. They are stronger and can handle heat treatment. They are less flexible to shape compared to 304 and 316. Exotic alloys are also available, but they are only used in unique applications that demand exceptional resistance or strength. Stainless steel provide the right balance of performance, value, and choice for most industries.
