Fasteners will be the implements that hold your construction together. As such, these are the smallest and yet most vital elements in constructions. There are three types of fasteners for constructions. Permanent type fasteners, like rivets, have parts that you cannot disassemble.
On the other hand, semi-permanent fasteners, such as pins, can be disconnected — but with some damage to the fastener. Removable fasteners comprise those from nut and bolt suppliers and can be disconnected without damaging the fastener.
Regardless of your fastener choice, its material is one of the primary elements that will guide your selection. The following are your best fastener material options.
A significant portion of construction fasteners is made of carbon steel owing to its sheer strength and rust and corrosion-resistance. Mild steels have at most 0.25% carbon and are relatively cheap, ductile, weldable, machinable and tough.
Medium carbon steel has 0.25–0.6% carbon and has a high load carrying capacity and can be heat-treated to enhance its mechanical strength. Alloyed carbon steel has manganese levels of more than 1.65% and copper or silicon levels of at least 0.60%.
This is a lightweight material, usually alloyed to boost its strength for fastening. Aluminium is non-magnetic, can be cold and heat forged easily and has thermal and electrical conductivity. Using aluminium fasteners for your project also reduces the risk of galvanic corrosion.
This is the prevalent copper-based alloy used in construction. Brass fasteners are ductile, strong and inexpensive. 360 brass is the popular fastener material choice because it closely mirrors the properties of steel fasteners and maintains its strength even in demanding conditions.
No single material option from the above will suit all construction environments. The ideal choice for your project depends on your project’s desired corrosion, fatigue, temperature, strength and vibration properties, among others.
Work with a supplier with a varied stock range to ensure you suffer no downtime and get the best fastener for your project.
