Bolts, screws and studs are the most common types of threaded fasteners. They are used in both permanent or removable joints.
Bolts: They are basically threaded fasteners normally used with nuts.
Screws: They engage either with a preformed or a self made internal threads.
Studs: They are externally threaded headless fasteners. One end usually meets a tapped component and the other with a standard nut. There are different forms of bolt and screw heads for a different usage. These include bolt heads of square, hexagonal or eye shape and screw heads of hexagonal, Fillister, button head, counter sunk or Phillips type. These are shown in figures-4.3.1.1 and 4.3.1.2.
Tapping screws
These are one piece fasteners which cut or form a mating thread when driven into a preformed hole. These allow rapid installation since nuts are not used. There are two types of tapping screws. They are known as thread forming which displaces or forms the adjacent materials and thread cutting which have cutting edges and chip cavities which create a mating thread.
Set Screws
These are semi permanent fasteners which hold collars, pulleys, gears etc on a shaft. Different heads and point styles are available. Some of them are shown in figure-4.3.1.3.
Thread forms
Basically when a helical groove is cut or generated over a cylindrical or conical section, threads are formed. When a point moves parallel to the axis of a rotating cylinder or cone held between centers, a helix is generated. Screw threads formed in this way have two functions to perform in general:
(a) To transmit power - Square. ACME, Buttress, Knuckle types of thread forms are useful for this purpose.
(b) To secure one member to another- V-threads are most useful for this purpose.
Some standard forms are shown in figure-4.3.2.1 V-threads are generally used for securing because they do not shake loose due to the wedging action provided by the thread. Square threads give higher efficiency due to a low friction. This is demonstrated in figure- 4.3.2.2.
4.3.2.1F- Different types of thread forms .

FAQs on Threaded Fasteners - Design of Machine Elements - Mechanical Engineering
| 1. What are threaded fasteners in mechanical engineering? |  |
Ans. Threaded fasteners are hardware devices used to mechanically join or secure two or more objects together. They consist of a threaded shaft or rod with a head on one end and a threaded portion on the other end. These fasteners, such as screws, bolts, and nuts, create a strong and reliable connection by engaging with the corresponding threads in the mating parts.
| 2. How do threaded fasteners work? | |
Ans. Threaded fasteners work by utilizing the principle of helical threads. The threaded portion of the fastener is inserted into a pre-drilled hole or a threaded hole in the mating part. As the fastener is rotated using a tool, such as a screwdriver or a wrench, the threads on the fastener engage with the threads in the mating part, creating a secure connection. The tightening of the fastener causes a clamping force between the two parts, preventing them from separating.
| 3. What are the advantages of using threaded fasteners? | |
Ans. Threaded fasteners offer several advantages in mechanical engineering applications. Firstly, they provide a strong and reliable connection, ensuring that the joined parts stay securely in place. Additionally, threaded fasteners can be easily installed and removed using basic tools, allowing for disassembly and repair. They also offer versatility, as different types and sizes of fasteners can be used depending on the application. Lastly, threaded fasteners allow for adjustments or tightening as needed, providing flexibility in assembly and maintenance.
| 4. What factors should be considered when selecting threaded fasteners? | |
Ans. When selecting threaded fasteners, several factors should be considered. These include the material and strength requirements of the joined parts, the load or force the fastener will experience, the environmental conditions (such as temperature and corrosion), the required level of tightness or torque, and the desired appearance or aesthetics. Additionally, factors like cost, availability, and compatibility with existing fasteners or systems should also be taken into account.
| 5. What are some common applications of threaded fasteners in mechanical engineering? | |
Ans. Threaded fasteners find applications in various mechanical engineering fields. They are commonly used in automotive, aerospace, construction, and machinery industries. Some specific applications include securing structural components, assembling machinery and equipment, fastening electrical enclosures, joining pipes and fittings, and attaching components in consumer products. Additionally, threaded fasteners are also used in woodworking, furniture manufacturing, and DIY projects.
