Set Screw | Material Selection, Point Types, Applications

By | April 25, 2019

Set screw (also known as Grub screw) is a special type of screw which is used to prevent relative moment of two parts. Unlike screw, a set screw is threaded over its entire length. In many applications, a setscrew is used instead of key to prevent relative motion between the hub and the shaft. The… Read More: Set Screw | Material Selection, Point Types, Applications »

Nut | Types and Material Selection [Explained in Detail]

By | April 22, 2019

Nuts are internally threaded fasteners. They have internal tapping. They are generally meant to be used with bolts. Together nut and bolt is used to assemble mechanical parts. Bolt is a male part and nut is a female part. Nuts are generally made of metals. Types of nuts There are basically two types of nuts… Read More: Nut | Types and Material Selection [Explained in Detail] »

Bolt | Types, Parts, Manufacturing, Material Selection, Applications

By | April 25, 2019

A bolt is a type of threaded fastener (like a screw) and is a male part. It is generally made of a metal. It is used to keep two or more hardware parts together (in a specific position). Shank of the bolt is only partially threaded, just to accommodate a nut. A bolt is sometimes… Read More: Bolt | Types, Parts, Manufacturing, Material Selection, Applications »

Screw | Types, Parts, Manufacturing, Material Selection, Applications

By | April 25, 2019

Screws are fasteners with helical grooves on their shank. These grooves can be either throughout the shank or only in the beginning. These grooves provide necessary friction and traction to avoid pull-out. They are generally made from a metal. A screw is sometimes also known as cap screw or tap bolt. Note: Those who don’t… Read More: Screw | Types, Parts, Manufacturing, Material Selection, Applications »

By | March 10, 2019

What is a Hydraulic Jack? Before directly jumping on to Hydraulic Jack, let’s first understand ‘Jack’. A jack is a device which is used to lift heavy loads. A jack could be Mechanical, Electrical or Hydraulic, based on the method of force generation. A hydraulic jack works on the basis of Pascal’s law. A small… Read More: Hydraulic Jack | Working, Application, Advantage, Disadvantage »

Lead Screw | Applications, Advantages, Disadvantages, Types

By | March 10, 2019

What is a lead screw? Lead screw is a type of screw which is used as linkage in machines. It converts rotary (or turning) motion into linear motion. Due to large contact area between male and female members of a lead screw, it has very high frictional losses. Advantages of lead screws They are generally… Read More: Lead Screw | Applications, Advantages, Disadvantages, Types »

Chain Drive | Definition, Types, Advantages, Disadvantages

By | March 10, 2019

What is a chain drive? Before understanding chain drive, let us first understand ‘What is a Chain?’. A chain can be defined as a series of links connected by pin joints. Now we can move on to chain drive. A chain drive consists of an endless chain wrapped around two sprockets. Advantages of chain drive… Read More: Chain Drive | Definition, Types, Advantages, Disadvantages »

Brakes I Definition, Types, Advantages, Disadvantages [Full Guide]

By | December 16, 2021

What is a Brake? Brake is a mechanical device which absorbs kinetic energy of moving systems and brings them to rest. This absorbed kinetic energy is converted into heat and then dissipated to the environment. One of the well-known use of brakes is in automobiles, where they are used to either slow down or stop… Read More: Brakes I Definition, Types, Advantages, Disadvantages [Full Guide] »
