The Differences Between Pan Head Screws And Round Head Screws
Because of the similar appearance, it is sometimes difficult to distinguish between pan head and round head screws, which will bring trouble to the procurement personnel. In fact, screws of different head types have different uses. As a professional fastener supplier, Xinchi Fasteners Company will introduce the difference between pan head screws and round head screws in this article, in order to help you choose pan head screws correctly.
The differences between pan head and round head screws:
The difference in shape: The most intuitive difference between a pan head screw and a round head screw is the difference in shape. Of course, the shape here mainly refers to the head type. A round-head screw has a round head and is semicircular when viewed from the side, while a pan-head screw has a round head and is trapezoid when viewed from the side.


The difference in definition: Round-head screws include a larger range, as long as the screw head is round, then these screws can be called round-head screws. But if the head shape of the screw is a pan head, it can only be called a pan head screw. Round head screws include pan head screws, large flat head screws and so on. In short, as long as the screw head is round, the screw can be called a round-head screw.
The difference in groove type: Round head screw only has a slot head type, while pan head screw has a cross slot head type and a slot head type.
The difference in the scope of application: Pan head screws and round head screws have the characteristics of insulation, no magnetic, anti-corrosion, beautiful, high-use strength, which is almost similar to metal, so they are widely used in the medical equipment industry, electronics industry, office equipment industry, and so on. The head of the pan head screw has an obvious arc, which is generally used for the internal workpiece or the workpiece that is invisible. Because of the head type of the round head screw, the semicircular screw head after installation is exposed to the installation surface, which is often used on the workpiece with low requirements for fastening appearance.
The difference in material usage: For pan head screws and round head screws of the same specifications, the volume, weight, and surface area of the round head screws are significantly larger than the disc head screws.
How to choose pan head screws correctly?
The pan head screws are available with either a slotted or a cross slotted. However, if an electric screwdriver is used, a cross-slotted pan head screw is generally used. If the connection requires higher corrosion resistance, it is best to use stainless steel material pan head screws. If the torque is required, in case of breaking, the carbon steel and hard material of the pan head screw are good. If there are not too many requirements about the quality, just for tightening the connection, it is ok to choose ordinary iron pan head screws.
