What Are The Fasteners Other Than Screws?

We often say fastener screws, fastener screws, are fasteners only screws and bolts?

▲Nut: The nut is used together with the screw. It has internal threaded holes, and the shape is a flat hexagonal column, or a flat square column or a flat cylindrical shape. When used, it is used with bolts, studs or machine screws. It is used to fasten and connect two parts so that they become a whole.

▲Wood screws: Similar to self-tapping screws, but the thread of the wood screw has a special thread for wood screws, which can be directly screwed into a wooden workpiece, or a metal or non-metallic part with a through hole can be tightened with a wooden workpiece. They are fixed together, and this tight connection can also be dismantled.

▲Washer: A type of fastener in the shape of an oblate ring. Generally placed between the supporting surface of the bolt, screw or nut and the surface of the connecting parts, it plays the role of increasing the contact surface area of the connected parts, reducing the pressure per unit area and protecting the surface of the connected parts from damage; another type of elastic washer , can also play a role in preventing the nut from loosening.

▲Retaining ring: It is installed in the shaft groove or hole groove of the machine and equipment, and plays the role of preventing the left and right movement of the parts on the shaft or on the hole.

Pins: Mainly used for part positioning, and some can also be used to connect parts, fix parts, transmit power or lock other fasteners.

▲Rivet: A type of fastener consisting of a head and a shank, used to fasten and connect two parts (or components) with through holes to make them a whole. This form of connection is called rivet connection, or riveting for short. It belongs to the non-detachable connection. Because to separate the two parts that are joined together, the rivets on the parts must be broken.

▲Assembly and connection pair: Assembly refers to a type of fasteners supplied in combination, such as a combination of a certain machine screw (or bolt, self-supplied screw) and a flat washer (or spring washer, lock washer), as shown above The connection pair refers to a type of fastener that uses a combination of certain special bolts, nuts and washers, such as high-strength hexagon head bolt connection pair for steel structures.

▲Welding nail: a heterogeneous fastener composed of a nail rod and a nail head (or no nail head), which is fixed and connected to a part (or component) by welding so as to be connected with other parts.
