Nuts are nuts. They are the same object. The differences between screws, bolts and nuts are as follows:
1、 Different appearance
- Safety screw: the one with sharp head at the front end, large pitch, and inclined circular rotating body structure.
- Safety bolts: cylindrical threaded fasteners with nuts, including hexagon head, round head, square head, countersunk head, etc.
- Safety nut: generally flat hollow polyhedral cylinder structure.
2、 Different functions
- Safety screw: It is a tool that uses the physical and mathematical principles of the circular rotation of the inclined plane of the object and the friction force to fasten the artifacts and parts step by step.
- Shearbolt: mechanical part, cylindrical threaded fastener with nut. A type of fastener consisting of head and screw (cylinder with external thread) shall be matched with nut to fasten and connect two parts with through-hole.
- Safety nut: the nut is a part that closely connects mechanical equipment. The nut and bolt of the same specification can be connected together through the inner thread.
3、 Different applications
- Safety screws: screws are indispensable industrial necessities in daily life: such as cameras, glasses, clocks, watches, electronics, etc; General screws for TV, electrical products, musical instruments, furniture, etc; Large screws and nuts are used for projects, buildings and bridges; Transportation appliances, airplanes, trams, automobiles, etc. are used for large and small screws.
- Shearbolt: bolts are indispensable in daily life and industrial production and manufacturing, and bolts are also known as industrial rice. It can be seen that bolts are widely used. The application scope of bolts includes electronic products, mechanical products, digital products, electrical equipment, electromechanical mechanical products, etc.
- Safety nut: mainly used in automobile industry — cars, trucks, buses, compressors, construction machinery, wind power generation equipment, agricultural machinery, fasteners, casting industry, drilling equipment.
