Detailed Information

What are square nuts used for?

Most of the time, square nuts are used where there is an inset or channel in the receiving surface, such as in furniture, railroad applications, or other metal assemblies. Because they have more surface area, square nuts are less likely to come loose.

Prashaant Steel & Alloys is a top Square Nut maker and a high-quality store. Square Nuts that we make are very popular in the industry because of how well they resist corrosion. People say that our Square Nut at Prashaant Steel & Alloys are of the highest quality, which is why we only use the best raw materials in the manufacturing process. The Square Nut has a high level of corrosion resistance and oxidation, which means it can be used in a lot of different ways.

Square nuts made of stainless steel are also called four-sided nuts. The sizes of these nuts range from 1 inch to 24 inches.

They are made of different types of high-tensile materials, such as 18-8 stainless steel, A2, A4, and others. There are both metric and imperial sizes. The M6 Square Nut is a metric nut that is used in hardware, car, petrochemical, oil and gas, general engineering, and construction applications. There are different standards for sizes, such as the DIN 557 Square Nut, DIN 934, DIN 982, DIN 936, and others.

The nuts could be made by cold forging, hot forging, or machining. Different ways of making the nuts led to nuts of different sizes. There are Heavy Square Nuts that are made for applications that need to hold more weight. They are also strong when pulled apart. On the metric scale, these can be any size from M2 to MI60. Different kinds of materials are used to make the different kinds of high tensile nuts. The nuts range from 3mm to 200mm in length. The M8 Square Nuts are made of austenitic stainless steel 316, which is very resistant to corrosion from chloride ions. The nuts also have a high tensile strength and can work at high temperatures, up to 870 degrees Celsius. Depending on

Depending on what the application needs are, the SS Square Nut can also come with different types of coatings.

Prashaant Steel & Alloys is a leading producer of Square Nutand a high-calibre retailer. Thanks to their excellent resistivity properties, the Square Nut That we manufacture are extremely popular in the industry. We are considered to have the excellent quality of Square Nutat Prashaant Steel & Alloys, which is why we use the highest quality of the raw materials used in the production processes. The Square Nut Provides outstanding resistance to corrosion and oxidation, which opens its doors to a wide range of applications. 

Stainless Steel Square Nuts are also known as four sided nuts. These nuts range from ¼ inches to 24 inches in size. They are made up of different material grades such as 18-8 stainless steel, A2, A4 and other high tensile materials. The sizes can be metric or imperial. The M6 Square Nut is a metric nut that is used in applications such as hardware, automobile, petrochemical, oil and gas, general engineering applications and in constructions. There are different standards to cover the dimensions such as the DIN 557 Square Nut, DIN 934, DIN 982, DIN 936 and others.

The nuts could be made of cold forging, hot forging or through machining. The different production methods made different sizes of the nuts. There are Heavy Square Nuts which are meant for heavier load bearing applications. They have high tensile strengths as well. These can range from M2 through M160 sizes in the metric scale. The different material types used differ for the high tensile nuts. The length of the nuts ranges from 3mm to 200mm. The M8 Square Nuts are made up of 316 austenitic stainless steel which has high corrosion resistance against chloride ion. The nuts also have high tensile strengths and high operating temperatures up to 870 degrees Celsius. Depending on the application requirements, different types of coatings are available for the SS Square Nut as well.

FAQ
Why are square nuts used?

What are square bolts called?

Before hex head bolts became the norm, square head bolts (also called square bolts) were the standard. Now, they are often chosen for their looks, either to give a new building a rustic look or to match fasteners on an old building.
