Know why these 4 types of Nuts and Bolts are important


A nuts and bolts is a type of a fastener with a threaded hole in it. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. In actuality, there are different types of nuts for bolts depending upon the shapes and sizes.

Nuts and bolt are like two partners, one cannot survive without each other. It is useless to have any of them. So it is essential to use both.

Let’s dive into the purely technical part of the nut and bolt.

It is applicable in a system where a rotation or a vibration has been taken place. As there are various locking mechanism may be employed.

Square nut as well as the bolt head first manufactured ever because of its manufacturing technique: can be made by own hand.

Nowadays hexagonal nut is the most used types of nuts for bolts. Six sides of hexagonal nut give a good granularity to a tool approach from (good in tight spots), but more (and smaller) corners would be vulnerable to being rounded off. It takes only one-sixth of a rotation to obtain the next side of the hexagon and grip is optimal.

A polygon with more than six sides does not give a good grip while with less then six sides takes more time to complete a rotation

Other specialized shapes exist for more configuration such as wing nut for finger adjustments and captive nuts for inaccessible areas. Details for different nuts are listed below.

Square types of nuts and bolts:

Also called as swage nut. Applicable only on sheet metal. Permanently anchor itself to the sheet metal by swaging the surronding material.

Only used when the requirement of torque is maximum. The greater side length allows spanner applied with a larger spanner area.

Technically speaking, square types of nuts for bolts are the four-sided nuts as suggested by the name. these are more suitable to be used with the flat washers so that their damage be avoided from its sharp edge. Square types of nuts for bolts can have standard, coarse, or fine threading with different platings.


Widely used in the manufacture of the furniture, and the rail channels

Wing types of nuts and bolts:

Wing types of nuts for bolts consist of two metal wings one on each side, so it can be easily tightened without tools. Similarly loosened

Popularly known as the wingnut, or the butterfly nut, these are similar to the shape of the butterfly wings. These are further of different types of nuts for bolts on the basis of the dimensional series, wing style, and variances


It can be used for bicycles, drums hardware, and seltzer bottles.

Thumb types of nuts and bolts:

Also called as swage nut or the knurled nut having a knurled outside the outer surface. Applicable only on sheet metal. Permanently anchor itself to the sheet metal by swaging the surrounding material.

The flange on the surface distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment. These may be mildly magnetic or not.


These can commonly be found on the surfaces of the electrical panel covers, precision measuring tools, squares, and service covers.

Dome types of nuts and bolts:

Also called acorn nut or the crown hex nut, blind nut, domed cap nut or simply the cap nut. A nut that has dome end on one side. There are two types of acorn nut:

  • Low acorn nut or standard acorn nut
  • High acorn nut

When used together with a threaded fastener with an external male thread, the domed end would enclose the external thread, this might happen either in order to protect the thread or to protect nearby objects from contact with the thread. Also, the dome gives a more finished appearance.


It is used for concealing ugly fasteners, securing sharp threads and thread protections.

This was all for the 4 types of nuts and bolts available with the guidance for their best possible usage. Hope the information being shared was quite helpful to you.
