Product Description Welcome to our homepage to see more content!Product DescriptionFastener InformationFasteners are a kind of mechanical parts used for fastening connections and are widely used. Fasteners, used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemical, metallurgical, mold, hydraulic and other industries, in a variety of machinery, equipment, vehicles, ships, railways, Bridges, buildings, structures, tools, instruments, chemical, instrumentation and supplies above, you can see a variety of fasteners, is the most widely used mechanical base parts. It is characterized by a wide variety of specifications, different performance uses, and the degree of standardization, serialization, and generalization is also extremely high. Therefore, some people have the national standard of a class of fasteners called standard fasteners, or referred to as standard parts. Fastener DetailsFasteners usually include the following 12 types of parts:1. Bolt: A fastener consisting of two parts, head and screw (cylinder with external thread), used in conjunction with a nut to fasten two parts with through holes. This type of connection is called bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.2. Stud: A type of fastener having no head and having only external threads at both ends. When connected, one end of it must be screwed into the part with an internal threaded hole, the other end through the part with a through hole, and then screw on the nut, even if the two parts are tightly connected into a single piece. This connection form is called a stud connection, which is also a detachable connection. It is mainly used for occasions where one of the connected parts is thick, requires compact structure, or is not suitable for bolted connection due to frequent disassembly.3. Screw: It is also a kind of fastener composed of two parts of the head and screw, which can be divided into three types according to the use: machine screws, setting screws and special purpose screws. Machine screws are mainly used for the fastening connection between a part with a tight threaded hole and a part with a through hole, without the need for nuts (this connection form is called screw connection, and it is also a removable connection; It can also be used in conjunction with nuts for fastening connections between two parts with through holes.) The setting screw is mainly used to fix the relative position between two parts. Special purpose screws such as ring screws for lifting parts.4. Nut: with internal threaded holes, the shape is generally shown as a flat hexagonal column, there are also flat square column or flat cylinder, with bolts, studs or machine screws, used to fasten the connection of two parts, so that it becomes a whole.5. Self-tapping screw: similar to machine screws, but the thread on the screw is a special self-tapping screw thread. Used to fasten the connection of two thin metal components, so that it becomes a whole, the member needs to make a small hole in advance, because the screw has a high hardness, can be directly screwed into the hole of the member, so that the member forms a response to the internal thread.6. Wood screw: it is also similar to machine screws, but the thread on the screw is a special wood screw thread, which can be directly screwed into the wooden member (or part), and is used to fasten a metal (or non-metal) part with a through hole to a wooden member. This connection is also a detachable connection.7. Washer: A type of fastener in the shape of an oblate ring. Placed between the supporting surface of the bolt, screw or nut and the surface of the connected part, it has the function of increasing the contact surface area of the connected part, reducing the pressure per unit area and protecting the surface of the connected part from being damaged; Another type of elastic washer can also play a role in preventing the nut from loosening. 8. Baffle ring: for installation in the shaft slot or shaft hole slot of the machine and equipment, it plays the role of preventing the parts on the shaft or hole from moving left and right. 9. Pin: mainly for parts positioning around, some can also be used for parts connection, fixed parts, power transmission or locking fasteners.10. Rivets: A type of fastener consisting of two parts of the head and the nail rod, used to fasten and connect two parts (or components) with holes to make it a whole. This connection form is called rivet connection, referred to as riveting. It is a non-detachable link. Because if the two parts connected together are separated, the rivets on the parts must be destroyed. 11. Components and connecting pairs: Assemblies are a type of fasteners that are supplied in combination, such as machine screws (or bolts, self-supplied screws) and flat washers (or spring washers, locking washers); Connection pair refers to a special bolt, nut and washer combination supply of a class of fasteners, such as steel structure with high strength large hexagon head bolt connection pair. 12. Welding nails: A heterogeneous fastener composed of a nail rod and a nail head (or no nail head), which is fixed on a part (or component) by welding method so as to connect with other parts.Product Parameters:Self-Drilling Drywall Anchors with Screws Anchors pre-drills precise hole in types of drywall ,no hole preparation required, made of durable zinc , easily removed.Deep thread design provides strong engagement , locks into many sizes of drywall 3/8", 1/2" or 5/8" gypsum wallboard.Product manufacturing process1, fastener product size standards: specify the content of the basic size of the product; Products with threads also include the basic size of the thread, the end of the thread, the shoulder distance, the cutting groove and the chamfer, the end size of the external thread part, etc.2, fastener product technical conditions standards. It mainly includes product tolerances, mechanical properties, surface defects, surface treatment, product testing standards and corresponding specific provisions.3, screw product acceptance inspection, marking and packaging standards: specify the product factory acceptance inspection project qualified quality level and sampling plan, as well as product marking methods and packaging requirements.4, standard parts, fasteners, screws, screws marking method standard: specify the product complete marking method and simplified marking method content.5, the standard of other aspects of fasteners: such as the standard of fastener terminology, the standard of fastener product weight, etc. Fields of applicationFasteners are a kind of mechanical parts used for fastening connections and are widely used. In all kinds of machinery, equipment, vehicles, ships, railways, Bridges, buildings, structures, tools, instruments, meters and supplies, you can see a variety of fasteners. It is characterized by a wide variety of specifications, different performance uses, and the degree of standardization, serialization, and generalization is also very high. Therefore, some people also refer to a class of fasteners that have national standards as standard fasteners, or referred to as standard parts.
