Difference between Nut and Bolts

Nuts and Bolts are one of the most important part for every assemblies, machines, automobiles, construction, manufacturing. Nuts and Bolts are used everywhere.

The nuts and bolts are required for tightening or loosening of two parts. They are one of the types of fastener. Here is the complete explanation and the difference between nuts and bolts.

What are Nuts?

Nuts are a type of fastener which are hexagonal in shape that has a threaded hole. Nuts plays an important role in fastening and cannot be used without bolts. Nuts are usually made of carbon steel coated with zinc.

The nuts have circular hollow cylindrical shape with internal threads with hexagonal shape at outer. There are various types of nuts which are used for many applications such as, Hex Nut, Lock Nut, Slotted Nut, Coupling Nut, Nylon Insert Jam Nut, Cap Nut, Wing Nut, Flange Nut, Castle Nut, Square Nut, Acorn Nut, etc.

What are Bolts?

Bolts are also a type of fastener which are hexagonal in shape on head with circular long solid thread shank. A bolt is an externally threaded. It can be fully threaded or partially threaded. Bolts are made of steel, chrome and nickel.

The bolts are used to join two parts together with the help of nuts. There are various types of bolts which are used for various applications such as, Hex Bolt, Anchor Bolt, Flange Bolt, Shoulder Bolt, Square Bolt, Stud Bolt, Eye Bolt, Tap Bolt, Toggle Bolt, Machine Bolt, Timber Bolt, etc.

Difference between Nut and Bolts:

Here is the difference between nuts and bolts are as follows,

Nuts	Bolts
Nuts are hexagonal in shape with hallow internal threads.	Bolts are hexagonal in shape on head with circular long solid thread shank.
Nuts are type of fasteners.	Bolts are also type of fasteners.
Nuts don’t have heads.	Bolts have heads for tightening and loosing.
Nuts are used with bolts for tightening.	Bolts are used with nuts for tightening.
Nuts have internal threads.	Bolts have external threads.
Nuts have locking mechanism to prevent from loosening.	Bolts don not have locking mechanism.
Nuts are smaller in size as compared to bolts.	Bolts are bigger in size as compared to nuts.
Nuts are hollow circular cylinders with circular cross section.	Bolts are solid circular cylinder with circular cross section.
The force involved on nut experiences compressive force.	The force involved on bolt experiences tensile force.
There are various types of Nuts such as, Hex Nut, Lock Nut, Slotted Nut, Coupling Nut, Nylon Insert Jam Nut, Cap Nut, Wing Nut, Flange Nut, Castle Nut, Square Nut, Acorn Nut, etc.	There are various types of Bolts such as Hex Bolt, Anchor Bolt, Flange Bolt, Shoulder Bolt, Square Bolt, Stud Bolt, Eye Bolt, Tap Bolt, Toggle Bolt, Machine Bolt, Timber Bolt, etc.
