Les boulons et les vis sont nos attaches de connexion courantes, qui jouent principalement le rôle de connexion et de fixation dans divers domaines et équipements. Beaucoup de gens confondent parfois les boulons et les vis, ce qui est facile à confondre. Aujourd'hui, je vais partager la différence entre les boulons de fixation et les vis. J'espère qu'il sera utile pour tout le monde d'utiliser des boulons et des vis à l'avenir.
La différence entre les boulons de fixation et les vis :
1. Fixation

des vissont définis différemment
Bolts: Bolts are cylindrical threaded fasteners that are paired with nuts during use. It is mainly used to fastenetconnect two parts with through holes. This connection form is called bolt connection.
Screws can also be called des vis. A screw is a tool that uses the physicsetmathematics principles of the oblique circular rotation of the objectetthe friction force to cyclically fasten objectsetparts. 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,etpress its end against the surface of another part, that is, fix the former part on the latter part.2. The shapeetstructure of fastener boulonsetdes vis are different
Bolt: A type of fastener consisting of a headeta screw (cylinder with external threads). The head is mostly hexagonal, which is generally larger.
Screw: A type of fastener composed of two parts: a headeta screw. The heads are mostly flatetcross grooves,etthere are many internaletexternal hexagons, which are generally small.
3. Fixation

des vissont utilisés différemment
Boulons : généralement utilisés par paires avec des écrous, pour les trous traversants, faciles à remplacer après des dommages.
Screws: usually do not need a nut, directly matched with two objects (generally, the connecting piece needs to be drilledettapped), which is mostly used for blind holes,etthe connected piece is rarely removed.

Les boulons utilisent généralement des outils de type clé.
Les vis utilisent généralement des outils de tournevis.
5. La fixation de l'attache

des visest différent
Les boulons sont généralement utilisés avec des écrous ou vissés dans des trous de boulons usinés.
In addition to the two fastening methods of boulons, there are self-tapping des vis, which are directly screwed into a soft workpiece without processing bolt holes. For example, the wood des vis we call are this kind of des vis.
6. Fastener boulonsetdes vis are used in different occasions
Boltsetdes vis are used in different places. Bolts do not require high precision. Unless there is a matching requirement, boulons are generally easy to disassemble, have low machining accuracy,etare not limited by connecting materials. They are widely used. Bolts that require matching can withstand transverse directions. Load: The screw is compact in structure, but cannot be disassembled frequentlyetcannot withstand large forces.
