Fastener Materials: A Look at Different Types

SteelIn construction, each part to make a whole, no matter how small or simple it is, matters. Therefore, part of usual maintenance instructions in machines is the checking of screws and bolts, aside from the usual inspection of bigger parts.

Like main parts, however, small fastening tools are also made up of different materials. Your supplier might recommend stainless steel bolts and nuts for one project and brass bolts and nuts for the other.

But why is there a need for such distinction? 

Steel

This is the most common fastener material due to its strength and durability. Steel fastener comes in a variety of types, like stainless steel, galvanised steel, and alloys, among others. It also comes in various bolt grades: Grade 2 is the standard bolt type usually found in hardware stores.

Grade 5 is stronger than Grade 2 and people use them in automotive materials, while Grade 8 is stronger than Grade 5 and used for more demanding automotive parts.

Aluminium

This is the least costly among all the other types of fastener metals, known for its light, soft and corrosion resistant properties. Aluminium fasteners also come in different grades and are sometimes equal or exceed the tensile strength of mild steel.

Brass

Brass can easily be shaped into anything and still remains strong and durable. It is nonmagnetic and has a higher degree of lustre. Unlike steel and aluminium, however, brass is worked by using cold temperature.

Copper

Copper has a high conductivity and malleability. Aside from that, copper is also a popular choice in construction because it is corrosion resistant. Although classified as non-precious metal because the world is abundant is copper supply, the quality of fasteners from copper is also notable.

So, the next time you have a construction project, take note of the fasteners that you will be using. They play a huge role in the success of your project.
