Different types of commonly used material for nuts and bolts.

Be it construction or any other major industry the role of nuts & bolts & other types of fasteners are critical. Thus, they determine the overall strength & structure of the largest structures. 

In case if you happen to have your business in the manufacturing or construction sector, we are sure that you would like to know what the commonly used materials for nuts & bolts by fasteners manufacturer in United States. So, let us make a look at the different types of materials used.

The different types of fastener materials used

Fasteners are made with a different variety of materials. These include everything from common steel to titanium, plastic & other materials. Some of these materials are again classified into different grades. This is done to describe some alloy mixtures, hardening as well as different processes involved. 

Apart from this some nuts & bolts are available with a variety of coatings and plating’s.  This is done to increase the resistance against corrosion and change the appearance of the fastener.

Fastener material is very much important when choosing a fastener due to keeping in view the strength, brittleness, corrosion resistance, galvanic corrosion properties. Cost of course is an important factor which determines which materials to choose. Let us now see fasteners' material in detail from fasteners exporter in United States.


Steel is the most common material used for making nuts & bolts & fastener material. These are available plain. They are also available with various surface treatments. These may include such as zinc plating, galvanization, & chrome plating. 

The grade of steel to be used may differ largely based on your different needs. They are usually available in 4 standard grades.

Alloy Steel

Alloy steel bolts are made from a high strength steel alloy. They are further heat-treated to make them stronger. These are mainly not plated, resulting in a dull black finish. These types of bolts are very strong. Nut they are very brittle at the same time.

Silicon Bronze

Silicon bronze often referred to simply as bronze. This is an alloy made mostly from a mix of copper & tin. They also contain a small amount of silicon. These are mainly in marine environments. It is often preferred to have silicon bronze over stainless in wooden boat construction. To know more about other material visit fasteners supplier in United States.


Brass is an alloy that is primarily made from a mix of copper & zinc. This alloy happens to be highly corrosion-resistant. It is also electrically conductive. But this is usually not used in fasteners because of its relative softness.


Aluminum happens to be a light, soft, and a corrosion-resistant metal. Material like stainless steel, aluminum is known to be very corrosion resistant. Fasteners are made from different types of aluminum alloys. These can be with different elements such as manganese, silicon, iron, magnesium, zinc, copper, etc. Rivets are often made from aluminum alloys.


Nuts & bolts & other fasteners are often chrome plated & polished. This is mainly for appearance. Chrome plating provides corrosion resistance.  But this is very costly & thus not very popular. If you want to buy fasteners of different materials visit fasteners dealers in United States.
