What are the differences between fastener bolts and screws?
1.The definition of fastener bolts and screws is different:
Bolts: Bolts are cylindrical threaded fasteners that are paired with nuts during use. It is mainly used to fasten two parts with through holes. This connection form is bolted.
Screws, also known as screws, are tools that use the physical and mathematical principles of the circular rotation and friction of the bevel of an object to gradually tighten the objects and parts of the cycle. Its set screw is used to fix the relative position of the parts. The set screw is screwed into the screw hole of the part to be fixed, and its end is pressed against the surface of the other part, that is, the former part is fixed on the latter part.
2.The shape and structure of fastener bolts and screws are different:
Bolt: A type of fastener consisting of a head and a screw (a cylinder with an external thread). The head is mostly a hexagonal head and is generally larger.
Screw: A type of fastener consisting of a head and a screw. The head is mostly a slot, a cross slot, and there are many internal and external hexagons, which are generally small.
3.The application of fastener bolts and screws is different:
Bolts: Generally used in pairs with nuts for through holes. They can be easily replaced after damage.
Screws: Generally, no nuts are required, and they are directly matched with two objects (generally, the connecting parts are first drilled and tapped). They are mostly used for blind holes, and the connected parts are rarely removed.
4.Fastening bolts and screws use different tools:
Bolts are generally tools such as wrenches.
Screws generally use screwdrivers.
5.The fastening of fastener bolts and screws is different:
Bolts are usually used in conjunction with nuts or screwed into machined bolt holes.
In addition to the two fastening methods of bolts, there are self-tapping screws, which are directly screwed into relatively soft workpieces without machining bolt holes, such as what we call wood screws.
6, fastener bolts and screws are used differently:
The places where bolts and screws are used are different, and the bolts do not have high accuracy requirements. Unless there is a coordination requirement, the bolts are generally easy to disassemble, the processing accuracy is low, and they are not limited by the connection material. Load; the screw is compact in structure, but cannot be dismantled often and cannot withstand large forces.
