What are the differences between machine screws and ordinary screws?

Machine screws and ordinary screws are two different types of threaded fasteners, and they have many differences in usage. Machine screws are usually used in mechanical equipment and industrial equipment, while ordinary screws are used in various situations in daily life. Now let's take a detailed look at the differences between machine screws and ordinary screws.

1. Size difference

The sizes of machine screws and ordinary screws are different. Machine screws are usually larger than ordinary screws because they need to withstand greater force and pressure. The size of machine screws is usually measured in inches or millimeters, while the size of ordinary screws is usually measured in centimeters or millimeters.

2. Material difference

The materials of machine screws and ordinary screws are also different. Machine screws are usually made of high-strength alloy steel or stainless steel to ensure that they can withstand high pressure and high temperature. Ordinary screws are usually made of ordinary carbon steel or iron because they do not need to withstand too much force and pressure.

3. Thread shape difference

The thread shapes of machine screws and ordinary screws are also different. Machine screws usually have deeper threads to ensure that they can better fix in mechanical equipment and industrial equipment. Ordinary screws usually have shallower threads to make it easier to rotate and tighten.

4. Usage difference

The usage of machine screws and ordinary screws is also different. Machine screws are usually used in mechanical equipment and industrial equipment, such as cars, airplanes, ships, robots, etc. Ordinary screws are used in various situations in daily life, such as furniture, appliances, doors and windows, bicycles, etc.

Although machine screws and ordinary screws are both threaded fasteners, they have significant differences in size, material, thread shape, and usage. When choosing threaded fasteners, we should select the appropriate ones according to the specific usage situation and requirements to ensure that they can perform their best.
