Bolts and screws are our common connection fasteners, which mainly play a role of connection and fixing in various fields and equipment. Many people sometimes mistake bolts and screws, which is confusing. Today I will share the differences between fastener bolts and screws. I hope that it will be helpful for everyone to use bolts and screws in the future.

The difference 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 the object to gradually tighten the objects and parts. And 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, fastener bolt and screw shape structure is 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, etc., 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 and can be easily replaced after damage.

Screw: Generally, no nut is needed, and it is directly matched with two objects (generally, the connecting part must be drilled and tapped). It is mostly used for blind holes, and the connected part is rarely removed.

4. Fastener bolts and screws use different tools:

Bolts are generally tools such as wrenches.

Screws are generally used for screwdrivers.

5.The fastening of fastener bolts and screws is different:

Bolts are usually used with nuts or screwed into the processed bolt holes.

In addition to the two fastening methods of bolts, there are self-tapping screws for screws, which are directly screwed into relatively soft workpieces without machining bolt holes, such as what we call wood screws.

6.The use of fastener bolts and screws is different:

The places where bolts and screws are used are different, and the bolts do not require high accuracy. 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 materials. Load; the screw is compact in structure, but cannot be dismantled often and cannot withstand large forces.
