Our system has many standards, such as standardization, serialization, personalization, and networking. The expected common standard parts are as follows.
Fastener head: A head is a type of rotating fastener that can penetrate deep into the head and convert the rotating point into a tight solid. The fastening body is located on one side of the head to facilitate the end face.
Regarding standardization, the standardized fastener system is to standardize these structures, manufacturing methods, manufacturing specifications, appearance, structure, and packaging, and has a high degree of standardization. There are two types of standard parts, one is standard parts and the other is non-standard parts.
● Fastener: refers to the general name of a kind of Machine element used to fasten and connect two or more parts or components into a whole, namely fasteners.
Common standard parts include mold standard parts, automotive standard parts, etc. When we purchase standard parts, we often use them. It is important to have a timely understanding of such standard parts. Let’s take a look at the relevant product knowledge below!
Bolt: A type of fastener consisting of a head and a screw (cylindrical body with external threads), which needs to be matched with a nut and used to tighten and connect two parts with through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, it can separate these two parts, so bolt connection is a detachable connection.
Nuts: with internal threaded holes, generally in the shape of a flat Hexagonal prism column, and also in the shape of a flat square column or a flat cylinder, which are used to fasten and connect two parts together with bolts, studs or machine screws to form a whole.
Washers: A type of fastener with a flat circular shape. Placed between the support surface of bolts, screws, or nuts and the surface of the connecting parts, it plays a role in increasing the contact surface area of the connected parts, reducing pressure per unit area, and protecting the surface of the connected parts from damage; Another type of elastic washer can also prevent the nut from loosening.
The previous common thread tightening methods for fasteners include: cylindrical head screw (half round head bolt) riveting, core pulling rivet (countersunk head bolt) riveting, and integrated type.
Lining nut: With internal threaded holes, the shape is generally hexagonal, and there are also flat round ones, which are used to match bolts and nuts.
Heat permeable area of fasteners: It is useful to avoid generating a large amount of heat after zero time mechanical accidents, and is necessary for cooling, softening, galvanizing, and other rust prevention purposes.
Used in various flammable and large temperature difference workpieces and environments, mainly for major equipment, transportation pipelines, heavy equipment, easily worn, flammable gases, and water.
The biggest benefit of using it in various humidity levels is that it can maintain rust resistance for a long time and does not require screws to come into contact with indoor media to work together.
