What are High Tensile Fasteners?
September 20, 2023

High tensile fasteners are a special kind of fastener that can withstand extreme tension and stress without breaking.

What is Tensile Strength?

High-tensile nuts and fasteners are an exceptionally sturdy variety of fasteners because of their ability to resist forces without breaking or deforming.

What are High Tensile Fasteners Best For?

High Tensile Fasteners may or may not be the best choice for your project, depending on the specifics of your engineering plans. Contact the experts at Fluton Valves for High Tensile Fasteners, and choose from our wide selection of quality products available in a variety of grades and thread pitches.

When to Use High Tensile Fasteners

High tensile fasteners are used when superior strength and durability are necessary.

Here are Some of the Applications of high tensile fasteners

Structural Applications

High tensile fasteners may be used in the construction of bridges and other infrastructure.

Automotive & Aerospace

Automotive and aerospace engineering, which frequently encounters stress and vibration, rely heavily on high tensile fasteners. As was previously mentioned, a higher thread pitch is typically used to achieve a more robust outcome.

Heavy Machinery & Equipment

High tensile Fasteners are used in heavy machinery and equipment in industries where stress and vibration are common, such as mining, agriculture, and construction.

Marine Applications

Offshore and marine applications may also make use of High Tensile fasteners due to the increased stress, tension, and vibration that these environments present.

Ways high-strength fasteners differ from other fasteners

Fasteners can be distinguished from one another in a number of ways, including the components used in their construction, the method of production, the fastener’s dimensions, the metric system used, and the thread pitch. Thus, high tensile fasteners differ from other types of fasteners in the following ways:


Carbon or alloy steel is used to create high tensile fasteners. Some fasteners, like those made of titanium, are used in aerospace applications, while others, like those made of stainless steel, are used in industrial settings.


Heat treatment is used to increase the tensile strength of high tensile fasteners. By relieving the material’s internal stresses, brittleness, hardening, and toughening are all eliminated, resulting in increased strength. Heat treatment is an essential part of high tensile Fasteners in order to achieve increased strength, though it may be used on other types of fasteners as well.


There is a wide variety of fasteners to choose from. High tensile Fasteners can be distinguished from lower strength Fasteners by a number of distinguishing features, including a thicker shank and a larger head diameter; however, larger dimensions are not always indicative of a high tensile bolt.

Thread Pitch

High tensile Fasteners come in both coarse and fine thread pitches, with the latter providing superior strength, vibration resistance, precision, and adaptability. Because of this, automotive fasteners typically have fine thread pitches.


High tensile fasteners are just like any other type of fastener in that they come in both metric and imperial sizes. To get a perfect fit when replacing a bolt, it’s crucial to also replace the system. High tensile Fasteners are available in both metric and imperial sizes from Fulton Valve (India) Pvt Ltd.

When not to Use High Tensile Fasteners

High tensile fasteners should be used sparingly, as they can make a project more expensive than it needs to be. Instances where high tensile might not be ideal include:

Low-Stress Applications

For low-stress uses, there is a wide variety of cheaper fasteners to choose from.

Corrosive Environments

The application itself will determine the optimal balance between strength and corrosion resistance. In comparison to high tensile fasteners, stainless steel fasteners provide superior resistance to corrosion.

High Temperature Environments

When exposed to extreme heat, high tensile fasteners may weaken or break. Titanium or nickel alloys could be better options in these circumstances.
