Bolts and screws are our common connection fasteners, in various fields and equipment mainly play the role of connection and fixation. Many people sometimes get bolts and screws wrong, which is easy to confuse. Today, I will share the difference between fastener bolts and screws. I hope it will be helpful for you to use bolts and screws in the future.

The difference between fasteners bolts and screws:

1. Fastener bolts and screws have different definitions:

Bolts: Bolts are cylindrical threaded fasteners that are paired with nuts during use. It is mainly used to fasten and connect two parts with through holes. This connection form is 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 an object to progressively tighten the parts of the object. The set screw is used to fix the relative position of the machine parts. Screw the set screw into the screw hole of the part to be tightened, and press its end tightly on the surface of the other part, that is, fix the former part on the latter part.

2. Fastener bolts and screws have different shapes and structures:

Bolt: a kind of fastener composed of two parts: head and screw (cylinder with external thread). The head is mostly hexagonal head, which is generally larger.

Screw: a type of fastener composed of two parts of the head and the screw. The head is mostly slotted, cross slotted, and there are many hex inside and outside, generally smaller.

3. Fastener bolts and screws have different applications:

Bolt: generally used in pairs with nuts, used for through holes, easily replaced after damage.

Screws: usually do not need nuts, directly matched with two objects (general connectors need to be drilled and tapped first) are mostly used for blind holes, and the connectors are rarely disassembled.

4. Fastener bolts and screws use different tools:

Bolts are generally used with wrench tools.

Screws are generally used with screwdriver tools.

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

Bolts are generally used in conjunction with nuts or screwed into processed bolt holes.

In addition to the two fastening methods of bolts, screws also have self-tapping screws, which are directly screwed into workpieces with relatively soft materials without machining bolt holes. For example, what we call wood screws is this kind of screws.

6. Fastener bolts and screws are used in different occasions:

Bolts and screws are used in different places. Bolts do not require high accuracy. Unless there is a matching requirement, bolts are generally easy to disassemble, have low processing accuracy, are not limited by connecting materials, are widely used, and bolts that require matching can withstand lateral direction. Load; screws are compact in structure, but cannot be disassembled frequently, and cannot withstand large forces.
