The Twins of the Fastener World?The Difference Between Bolts and Screws
Time: 2024-11-29 Source: Author:
As common twins in the fastener world, bolts and screws both consist of a screw and a head with similar head shapes, and are often easily confused. This article takes a look at the differences between bolts and screws.
Bolts, composed of two parts: the head and the screw (a cylinder with external threads), are a kind of rod-shaped parts that are connected to nuts via their external threads. The bolt needs to cooperate with the nut, used to fasten the connection of two parts with through holes. Screw part with external threads, used to pass through the connected parts of the through-hole. Bolts are widely used in mechanical engineering for detachable connections and are generally used in conjunction with a nut (usually with a washer or two washers).
A screw is a tool that uses the physical and mathematical principles of circular rotation and friction of the inclined plane of an object to tighten the parts step by step. It usually consists of a round head and a threaded rod, with a variety of head designs, such as flat head, Phillips head, etc., to facilitate manual or mechanical tightening. The rod is also externally threaded, but can be screwed directly into a pre-threaded hole in the connected part. Screws do not need to be used in conjunction with a nut and can be screwed directly into the prefabricated or threaded hole of the fastener being fastened.
Bolts usually require a nut to provide the tightening force, and the tight connection is realized by passing the screw of the bolt through the through-holes of the two connected parts and tightening it with a nut at the other end. This type of connection is particularly suitable where large loads are to be applied or where frequent disassembly is required. Screws, on the other hand, usually hold objects together by directly rotating itself. They do not require an additional nut to fit, and are therefore easier to use.
Since the head of a bolt is generally hexagonal, tools such as wrenches are required to tighten it. This ensures that the required tightening torque is achieved and that the connection is reliable. Screws have a variety of head designs and can be tightened with hand tools such as screwdrivers and drivers.
Bolts are widely used in machinery manufacturing, construction engineering, bridge structures and other fields due to their strong fastening ability and disassembly. Especially in the occasions that need to withstand great tensile force, pressure or shear force, the connection effect of bolts is more reliable. Because of their easy use and diverse head designs, screws are widely used in the assembly of electronic equipment, furniture, toys and other fields. The diversity and adaptability of screws make them an indispensable part of modern industrial production and daily life.
