What Is The Difference Between Flat Head Machine Screws And Round Head Machine Screws?

Flat head machine screws and round head machine screws are common types of screws, and they have some differences in shape and use. Below we will introduce their differences in detail, hope it will be helpful to you.

The shape difference:

Flat Hesad Machine Screws : Flat head machine screws have a flat surface at the top with a flattened shape, similar to a circle being flattened at the top. These screws are usually driven with a flat screwdriver or screw wrench.

Round Head Machine Screws: Round head machine screws have a rounded top with a cylindrical shape. These screws are usually driven with a cylindrical screwdriver or screw wrench. 

The difference in use:

Flat Head Machine Screws: Flat head machine screws are commonly used in applications where the screw needs to be buried in a surface. Due to their flat tops, when fastening flat head machine screws they can be embedded into the surface of the material so that the screw head is flush with the surface and does not protrude. This makes flat head machine screws very common in furniture manufacturing and assembly, as well as other places where exposed screw shanks are required.

Round Head Machine Screws: Round head machine screws are typically used in situations where the screw shank needs to be exposed or where a projection needs to be created on a surface. Due to their rounded tops, when round head machine screws are tightened, they create a bump in the surface that facilitates attachment with a nut or other fastener. Round head machine screws are commonly used in mechanical equipment and structural connections, such as automotive manufacturing, electronic equipment, and metal components.

Choosing the right type of screw depends on the specific needs of the application. In some cases, flat head machine screws provide a more aesthetically pleasing, low-profile appearance, while also enabling good hiding of the screw rod. Round head machine screws, on the other hand, are used in situations where the screw shanks need to be exposed or where they need to create a bump in the surface.

Additionally, both flat head and round head machine screws need to be driven with an appropriate screwdriver or screw wrench when installing them to ensure proper and secure attachment to the desired material.
