high tensil bolt

In order to understand the reason why high tensile bolts are such important fasteners and fixings to offer to your customers, you must first understand exactly what ‘high tensile’ means.

Tensile strength, also known as ultimate tensile strength or UTS, refers to the maximum amount of stress a bolt can withstand before it fails to perform correctly. When stress pushes industrial fasteners past their tensile strength, they may not only fail, but break as well. The amount of stress each bolt is able to withstand is defined by its grade, which is measured using force per unit area. For instance, an 8.8 grade high tensile bolt can withstand 45 to 49.9 metric tonnes for each 6.45 cm².

Because these fasteners and fixings have a higher tensile strength than a regular bolt, they are much more popular to use, and for good reason.

Why High Tensile Bolts are Popular to Use

There are several reasons why your customers would be more likely to purchase a high tensile bolt than any other.

· An 8.8 grading on industrial fasteners like bolts often means they are about two times as strong as a regular bolt. For many of your customers, this strength is vital.

· The tensile strength of these types of fasteners and fixings not only ensures that the bolt is able to function as it should, but that it won’t break under pressure.

· Offering high tensile fasteners and fixing to your customers allows them to feel safe in their purchase. When they see “high tensile” they automatically know you are providing them with a quality bolt that will enable them to complete their projects or tasks.

Why Zinc?

Many high tensile bolts on the market are a blackened colour. This is a defining characteristic caused by the process of creating these strong bolts. However, if you want to offer your customers high quality industrial fasteners, you need to go beyond the black and consider purchasing bolts with zinc plating.

Zinc is a powerful type of plating used on high tensile bolts, and is extremely popular as well. This type of plating comes with many benefits, include corrosion resistance, protection against white oxidation spots that may develop over time if the bolts are exposed to moisture, and they are extremely economical.

If a coating of zinc is too thick, the tensile strength can be affected. However, thinner coatings are often used to help maintain the strength and quality of these fasteners and fixings without sacrificing the fantastic benefits of zinc.

The two most common ways of applying zinc to threaded industrial fasteners like high tensile bolts is electroplating or hot-dip galvanising. Hot dip galvanising is a process in which the steel of the bolt reacts to the zinc, forming zinc and iron layers on the surface of the bolt. This ensures the bolt is protected in harsh environments and is less likely to incur mechanical damage.

For the ultimate in strength and dependability, consider the benefits of high tensile bolts. These fasteners are strong, won’t easily break under pressure, and are most often coated with zinc for added protection from environmental corrosives.
