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.
