What are fasteners in construction?

Fasteners, In construction, connectors between structural members. Bolted connections are used when it is necessary to fasten two elements tightly together, especially to resist shear and bending, as in column and beam connections. Threaded metal bolts are always used in conjunction with nuts.

We provide different type of fasteners & components for different type of Building construction design like Steel Frame Construction, RCC Construction etc.

Importance of a screw/fasteners

Screws are widely used in threaded fasteners to hold the objects together, mainly in devices such as screw tops for containers, vices, screw jacks and screw presses. A fastener can be a special type of nail that has spirals on its sides. The fasteners are used to make substances rigid and long-lasting and make it look clean as well.

Different types of fasteners are used in the industry for different purposes. An automobiles requirement for fasteners will be different from the requirement of that of a fastener that is used in an aeroplane. The fasteners hold the industry together.

In order to determine the specific fastener needed, the specifics of the application must be known to select the correct material. These factors include:

  • Accessibility of the area
  • What type of materials are being joined
  • Reusability of the fasteners
  • Weight of the materials
  • Surrounding environment, such as temperature and exposure to water and wind.
