In general, the manufacturing of fasteners is done in various different materials including titanium and common steel and some other exotic materials.
It is important to know what kind of fastener you are choosing while replacing the older one, it is not always safe to choose a stronger bolt and replace it with a weaker one. As the stronger bolt is more brittle and in specific applications it can fail.
Fasteners And Its Material
- Stainless Steel: it is an alloy of chromium and low carbon steel, it is a high corrosion resistance which is why it has enhanced corrosion characteristics at the price. During the installation or use, if the stainless steel is stretched, it will not lose its resistance.
A very common myth is that stainless steel is stronger than any regular steel, but it is not true, as stainless steel has low carbon, it is not possible for the stainless steel to be hardened by the heat treatment.
- Steel: it is the most common fastener manufactured and is also available in different surface treatments including plain, galvanization, zinc plating and chrome plating.
Steel is mostly available in 4 Grades: Grade 5, Grade 2, Grade 8 And Alloy Steel. There are other grades available too, but it is not as used as those. The plating in Grade 2, 5 and 8 are slightly yellow-ish or blue-ish either with galvanization or zinc coating.
- Silicon Bronze: it is an alloy that is referred to as bronze, which is made of largely tin or copper with a very little amount of silicon and is used in the environment of marines. As it has better corrosion resistance it is mostly favoured over stainless steel in the construction and re-fastening of a wooden boat.
It is also preferred over brass as silicon bronze has more strength in it. As bronze looks similar to copper in its colour, that is why it is used for woodworking for its appearances. The only drawback of bronze is its high cost.
- Brass: it is highly electrically conductive and corrosion-resistant, and is an alloy of zinc and primary copper. As it is relatively softer than other fastener materials, its use as a fastener is very limited and is used primarily for the looks of it.
- Aluminium: it is soft, light and a metal that is corrosion-resistant. Just like how stainless steel‘s corrosion resistance is inherited from its material, aluminium also has a similar attribute.
Many fasteners are manufactured with various alloys of aluminium which has the elements of silicon, manganese, iron, magnesium, copper and zinc added to it, as it helps in increasing the meting point and its strength.
