Difference Between Bolt And Screw
Bolts and screws are our common connection fasteners, which mainly play the role of connection and fixing in various fields and equipment. Many people sometimes get the bolts and screws wrong and easily confuse them.
As a professional fastener manufacturer, Xinchi is happy to share the differences between bolts and screws, hoping to help you use bolts and screws in the future.

- Bolts and screws are defined differently.
Bolt: A bolt is a cylindrical threaded fastener paired with a nut during use. It is mainly used to fasten and connect two parts through holes, and this connection form is called a bolt connection.
Screws, also known as screws, screws are tools that use the physical and mathematical principles of circular rotation and friction of the inclined plane of the object to tighten the tool parts gradually. The setting screws are used to fix the relative positions of the parts. Screw the tightening screw into the screw hole of the part to be tightened, and press its end on the surface of another part, that is, fix the former part on the latter part.
- Bolts and screws shape structure is different.
Bolt: A type of fastener composed of two parts: head and screw (cylinder with external thread), the head is mostly hexagonal first class, generally large.
Screw: A kind of fastener composed of two parts of the head and screw, the head is mostly a slot, a cross slot, and the internal and external hexagonal are also many, generally small.
- The application of Bolts and screws is different.
Bolts: Generally used in pairs with nuts, for through holes, easily replaced after damage.
Screws: usually do not need nuts, directly with the two objects (general connector first to drill, tap) for blind holes, the connected parts are rarely removed.
- Bolts and screws use different tools.
Bolts generally use tools such as wrenches.
Screws are generally subclassed with a tool.
- Bolt and screw fastening methods are different.
The bolt is generally used with the nut or screwed into the machined bolt hole.
In addition to the two fastening methods of bolts, there are self-tapping screws, which are directly screwed into the workpiece with soft material, without processing the bolt hole, such as the wood screw we say is this kind of screw.
- Bolts and screws are used on different occasions.
The use of bolts and screws is different, the accuracy of the bolts is not high, unless there is a matching requirement, the general bolt disassembly is convenient, the processing accuracy is low, is not limited by the connection material, is widely used, and the bolts that are required to be matched can bear the transverse load; The screw is structurally compact, but cannot be disassembled frequently and cannot withstand large forces.
