Importance of Fasteners

Have you heard about Boeing 747 jet airline? Yes, an American wide figure commercial jet airline often known as ‘Jumbo jets’, which have around 30 lakhs fasteners out of 60 lakhs parts. Fastener is a main hardware component which is used nearly everywhere, be it your door hinge or some house hold appliance, be it automobile, machineries, construction, infrastructure or all other items which require assembly will certainly have fasteners to affix them. What if a single fastener gets loose or broke down? It will surely affect the entire system or causes adverse consequences. So the strength, durability, rigidity depends upon the kind of material are we going to use or what should be the coating on it or what should be the dimension of it, because selection of correct fasteners will reduce the stress concentration which will reduce the fatigue. There are varieties of fasteners available in the market each with a specific reason to use which can be ferrous, non-ferrous or even plastic fasteners these days.

 

Screws 


These are the fasteners which create their own threads while fastening into the material. They typically have a head, and a shank with a helical threads .They have different types of head style and recess or drive style  such as slotted, Pozidriv, Phillips, hex, Torx, Robertson etc.( to know more about this, consider the previous article) .


Bolts and Nuts

 

A bolt is a threaded fastener which is always coupled with a nut. Bolts have external male thread and nuts have internal male thread.  A bolt comprises of a head, cylindrical body and threads along its length. Bolts are generally have the flat head which means there is no grove on the head. It generally has the design on its periphery to get driven by the wrench tool and same goes for the nut.

Washers

These are the thin plate, disc shape with a hole in the middle and generally the outer diameter is twice of the inner, which is used to distribute load over which it is fasten such as on screw or nut. These can also be used as a spacer, locking device, wear pad etc. in many applications. It can be of metal, plastic or rubber according to the requirement.
