The fastener is a hardware device that mechanically connects two or more objects together. Fasteners can also be used to shut down a container such as a bag, box. They may also involve keeping together the sides of an opening of flexible substance, connect a lid to a box/vessel, etc. Fasteners can be of many types like Bolt, Nut, Screw.
Then bolt is also a form of (sewing machine) fastener with an outward male thread. Bolts are used in a wide variety of head designs. These are designed to capture with the tool used to screw up them. The most general/usually used Bolt today is the hexagonal head.
The nut is also one variety of fastener with a threaded hole. Nuts are almost always used in coincidence with a mating bolt to fasten two or plenty parts together. The two ally are kept together by a mixture of their threads friction, a slight extension of the bolt, and contracting of the parts to be held together.The most usual shape of Nut is hexagonal.
The screw is also one form of the fastener and at sometimes similar to a bolt. It is generally made up of metal and characterized by a circular ridge known as a male thread. A screw is an inclined plane fold around a nail. Some screw threads are designed to mate with a complementary thread, known as a female thread. The most general uses of screws are to hold an item/thing together and to position item/thing. The screw will generally have a head on one side that contains a specially formed shape that allows it to be turned into a tool. The most general tools for driving screws include screwdrivers. The head is generally larger than the body of the screw which keeps the screw from operating in depth than the length of the screw and to give a bearing work surface.
The Some of the applications of the Fasteners are:
1. It is used in Sheet-metal assemblies.
2. It is used in Aircraft.
3. It is used in Air conditioners.
4. It is used in Engineering Field.
5. It is used in cold storage.
6. In Engineering Field.
7. In kitchen equipment.
8. In the Lighting industry.
9. In Office furniture
The Some of the advantages of the Fasteners are:
1. It is Corrosion Resistant.
2. It is having Strength.
3. It is Cosmetically Appealing.
4. It is Largely Non-Magnetic.
5. It is Reasonably Inexpensive.
6. It is Readily Available.
7. It is ROHS Compliant.
8. It is Ease of manufacturing.
9. It is Ease of assembly and transportation.
