How Many Differences do You Know Between the Bolts and the Screws in Fasteners?

Bolts and screws are a common connection fasteners, which mainly play a role in connection and fixation in various fields and equipment.A lot of people sometimes screw and bolt to the wrong, easy to confuse.China Hardware is going to share the differences between fastener bolts and screws today. I hope it will be helpful for you to use bolts and screws again in the future.

The difference between bolts and screws of fasteners:

1. Different definitions of bolts and screws for fasteners:

Bolt: A bolt is a cylindrical threaded fastener used in conjunction with a nut during service.It is mainly used for fastening and connecting two parts with through holes. This kind of connection form is called bolt connection.

The screw, also known as the screw, screw is the use of the object’s beveled circular rotation and friction force of physics and mathematical principles, the gradual cycle of fastening tools.The setting screw is used to fix the relative position of the machine parts.The setting screw is screwed into the screw hole of the part to be fixed, and the end of the screw is pressed on the surface of another part, that is, the former part is fixed on the latter part.

2. Different shape and structure of fastener bolts and screws:

Bolt: A type of fastener consisting of a head and a screw (cylinder with external thread), usually having a hexagonal head and generally larger head.

Screw: a kind of fastener composed of head and screw parts. The head is mostly a word groove, a cross groove, and a lot of hexagons inside and outside, generally smaller.

3, fastener bolt and screw application is different:

Bolts: usually used in pairs with nuts, for through holes, easily replaced after damage.

Screw: usually do not need nuts, directly with two objects (general connector first to drill, tapping) used for blind holes, connecting parts are rarely disassembled.

4. Different tools are used for fastener bolts and screws:

Bolts generally use wrench tools.

Screw generally use subclass tools.

5. Different fastening between bolts and screws of fasteners:

Bolts are usually used in conjunction with nuts or screwed into the holes of processed bolts.

In addition to the two fastening methods of bolts, there are also self-tapping screws, which are directly screwed to the workpiece with soft material without processing the bolt hole. For example, the wood screw we say is this kind of screw.

6, fastener bolts and screws used in different occasions:

The use of bolts and screws is different, the precision of the bolt is not high, unless there is a requirement to cooperate with the general bolt disassembly is convenient, low processing accuracy, is not limited by the connection material, widely used, the bolt required to cooperate with, can withstand the transverse load;Screw is compact in structure, but cannot be removed frequently, and cannot withstand large forces.
