Screw: A screw is usually composed of a screw and a head. The screw has external threads with various parameters such as thread shape, pitch, and diameter to adapt to different usage scenarios. There are various shapes for the head, such as hexagonal head, cruciform head, one character head, round head, countersunk head, and so on. Different head shapes are suitable for different tools, making it easy for users to tighten or loosen. For example, hex head screws are often operated with a wrench, while Phillips and Phillips screws correspond to Phillips and Phillips screwdrivers, respectively.
Nut: A nut is a block shaped component with internal threads that precisely match the external threads of a screw. The common shapes include hexagonal nuts, square nuts, etc. Among them, hexagonal nuts are the most commonly used because they provide a larger operating surface, are easy to tighten with a wrench, and can withstand larger torque. The size specifications of nuts are also very diverse, corresponding to the corresponding screw specifications one by one.
Screws and nuts come in various materials, commonly including carbon steel, stainless steel, copper, etc. Carbon steel material has low cost, certain strength and hardness, and is suitable for general mechanical connections and building structures. Stainless steel material has excellent corrosion resistance and can maintain good performance under harsh conditions such as humidity and chemical corrosion. It is commonly used in fields such as food processing equipment, medical devices, and ships that require high corrosion resistance. Copper screws and nuts have good conductivity and diamagnetism, and are widely used in electronic devices, electrical installations, and other fields.

How to choose the appropriate screw and nut specifications?
Firstly, it is necessary to clarify the material, thickness, and other factors of the connected object, and preliminarily determine the size range based on the required load capacity. At the same time, it is necessary to consider the usage environment, such as whether there is a risk of corrosion, in order to choose suitable materials and surface treatment methods. If used for specific equipment or industries, relevant standards and specifications must also be followed. In uncertain situations, you can consult professional hardware suppliers or refer to relevant technical manuals.
How to disassemble rusted screws?
You can try dropping some rust remover on the rusted screw first, and wait for a period of time for the rust remover to penetrate and soften the rust. You can also gently tap around the screw with a hammer to loosen the rust layer, and then try to disassemble it with a suitable tool. If the screws are severely rusted and none of the above methods are effective, you can consider using a cutting tool to carefully cut off the screws, but be careful not to damage the surrounding components.
Can screws and nuts of different materials be mixed for use?
It is generally not recommended to mix screws and nuts of different materials. Due to the differences in chemical and physical properties between metals of different materials, mixed use may cause electrochemical reactions, leading to accelerated corrosion and affecting the reliability of the connection. If mixed use is indeed necessary, full consideration should be given to the compatibility between different materials, and appropriate protective measures should be taken, such as adding insulation gaskets.
