We all know that screws are customized according to the purpose of the product. Of course, if we need a specific head shape and specification of screws, we have to choose the role of the screw head according to the slot or gap reserved in the workpiece.
Common screw head types include flat head, pan head, countersunk head, large flat head, hexagonal head, etc. So today, the custom screw manufacturer will take you to understand where different screw head types are used?
1. Flat head screw, from the appearance, the head of the flat head screw is at a 90-degree angle to the bolt connection part, and the head of the flat head screw is very thin, which is very suitable for the connection of mobile phones, watches, and other precision electronic components.
2. Pan head screw, its head has a clear curvature, generally used inside the workpiece or on invisible workpieces.
3. Countersunk screw, the entire head of the screw can be screwed into the workpiece without protruding the head of the screw. This is generally used for a firm connection on the outer surface of the workpiece to make the surface of the workpiece flat.
4. Hexagonal screws are commonly used in machinery. They are easy to fasten, easy to disassemble, and not easy to slip. The hexagonal screws on the market are mainly made of carbon steel, stainless steel, and copper.
5. Large flat head screws. Their heads are larger than those of semicircular head screws, and the force-bearing area is also larger. The product is not easy to damage the screw connection. There are more plastic parts in normal use.
