Screw Head Types
Screw Head Types
There are several types of screw heads, each with its own advantages and disadvantages.Fastener screws are hardware components that are used to securely join two or more objects together. They consist of a threaded shank with a head at one end and a pointed tip at the other end. The threads on the shank allow the screw to be rotated and driven into a material, creating a secure joint. Fastener screws are commonly made from steel, stainless steel, or other materials such as brass or aluminum, and are available in a wide range of sizes and shapes to suit different applications.

What are the screw headt types?
| Screw Head Type | Description | |
|---|---|---|
| Flat Head | The flat head screw has a countersunk head with a flat top surface and a cone-shaped bearing surface. This allows it to sit flush with the material it is installed in. | |
| Pan Head | The pan head screw has a slightly rounded top with a cylindrical bearing surface. It is often used in applications where a low-profile head is desired. | |
| Round Head | The round head screw has a dome-shaped head with a cylindrical bearing surface. It is often used in applications where a decorative or finished appearance is desired. | |
| Oval Head | The oval head screw has an oval-shaped head with a countersunk bearing surface. It is often used in applications where a finished appearance is desired, but a flat head screw cannot be used. | |
| Truss Head | The truss head screw has a low-profile, wide head with a flat top and a curved bearing surface. It is often used in applications where a low-profile head is desired, but a pan head screw does not provide enough support. | |
| Bugle Head | The bugle head screw has a low-profile head with a slightly rounded top and a conical bearing surface. It is often used in drywall installation, as the conical shape helps prevent tearing of the drywall paper. | |
| Cheese Head | The cheese head screw has a cylindrical head with a flat top and a curved bearing surface. It is often used in applications where a decorative appearance is desired. | |
| Countersunk | The countersunk screw has a conical head with a flat top surface and a cone-shaped bearing surface. It is often used in applications where a flush finish is desired, as the conical shape allows it to sit flush with the material it is installed in. | |
| Hex Head | The hex head screw has a six-sided head with a flat top surface and a cylindrical bearing surface. It is often used in applications where high torque is required, as the flat sides of the head allow for a better grip with a wrench or pliers. | |
| Socket Head | The socket head screw has a cylindrical head with a recessed, hexagonal socket in the center. It is often used in applications where a low-profile head is desired and where high torque is required, as the socket allows for a better grip with a wrench or socket wrench. | |
| Button Head | The button head screw has a low-profile, cylindrical head with a slightly rounded top and a cylindrical bearing surface. It is often used in applications where a low-profile head is desired, but a truss head screw is too wide. | |
| Cap Head | The cap head screw has a low-profile, cylindrical head with a flat top surface and a cylindrical bearing surface. It is often used in applications where a low-profile head is desired, but a button head screw is too rounded. |
