Why You Should Buy Stainless Steel Locknuts?

What are Locknuts?

A locknut is a type of fastener that is installed on another nut, mainly mating bolts, to fasten multiple parts together by the means of threads’ friction. Locknuts have internal machine threads that when mated with bolts resist loosening from vibration and torque. They are manufactured in a variety of materials, including stainless steel, carbon steel, cadmium coated alloys, and more.

Locknut material is an important factor while choosing your supplies. Stainless steel locknuts are considered the ideal choice for any application. You must be wondering why? There are many reasons why you should buy stainless steel locknuts. But let’s first understand what stainless steel is?

What is Stainless Steel?

Stainless steel is a generic term used to describe alloy steel that contains 30-40 percent chromium in conjunction with carbon, nickel, titanium, aluminum, copper, silicone, molybedenum, nitrogen, sulfur, selenium, phosphorous, and niobium. Stainless steel is known for its resistance to corrosion. There are different types of stainless steel available in a number of grades. They are found in four different categories including 300 series, 400 series, 455, and 430 (or 443).

Here are the reasons why you should buy stainless steel locknuts:


  1. Corrosion Resistance

Stainless steel locknuts have the highest degree of corrosion resistance than other locknut materials. This property is vital for the long life of the locknuts because of the environments they are used in. They are the perfect option for long-lasting applications because of their durability and stress corrosion cracking (SCC) nature.

  1. Self-Repairing

Stainless steel locknuts have a unique feature of self-repairing. When their inner threads or outer layer is scratched or damaged, it forms a new layer to protect the exposed material. Stainless steel contains chromium, which reacts to form a self-healing passive layer of oxide where there is any damage.

  1. High Tensile Strength

Locknuts need to be very strong because of the continuous jolts, vibrations, and torque they experience in a given environment. Locknuts made of stainless steel are very strong and have high tensile strength. Tensile strength is defined as the maximum load a material can withstand before breaking or cracking. For instance, type 304 Stainless Steel has 73200 psi Ultimate Tensile Strength and 31200 psi Yield Tensile Strength.

  1. Low Maintenance

Every business looks for materials, systems, and machines that require less maintenance to save their costs. As compared to other locknut materials, stainless steel is a low maintenance material because it is resistant to corrosion and can repair itself. It may cost you more originally but will provide you long-lasting value. So you will save maintenance costs in the long run.


The aforementioned reasons are enough to convince you why you should buy stainless steel locknuts for your next project.
