What does the part consist of

Wood screws are also similar to machine screws, but the thread on the screw is special. Wood screws can be directly screwed into wooden components or parts and are used to fasten a metal or non-metal part with a through hole to a wooden component. . This connection is also a detachable connection.
A type of fastener in the shape of an oblate ring. It is placed between the supporting surface of the bolt, screw or nut and the surface of the connecting part to increase the contact surface area of ​​the connected part, reduce the pressure per unit area and protect the surface of the connected part from being damaged. Another type of elastic washer can also play a role in Prevent the nut from loosening back.
The retaining ring is installed in the shaft groove or hole groove of the machine and equipment to prevent the parts on the shaft or the hole from moving left and right.
Pins are mainly used for part positioning and some are also used for part connection, fixing parts, transmitting power or locking other fasteners.
A type of fastener consisting of a head and a shank is 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 certain machine screw or bolt, self-supplied screw and flat washer or chipboard screw Suppliers spring washer, lock washer. A class of fasteners supplied in combination with washers, such as high-strength hexagon head bolt connections for steel structures.

Welding nails are fixed and connected to a part or component by welding to connect them with other parts.
Wire threaded insert Wire threaded insert is a new type of threaded connection element, which is refined from high-strength, high-precision corrosion-resistant diamond-shaped wire. When a spring is installed in a specific screw hole of the base body, its inner surface forms a standard thread when it cooperates with the screw and bolt, it can significantly improve the strength and wear resistance of the threaded connection; especially on low-strength materials such as aluminum, magnesium, cast iron, and plastic. The locking type is to add one or several locking rings on the basis of the ordinary type. Xinxiang Yongda Industrial Co., Ltd. is a manufacturer specializing in the production of wire thread inserts. It is recommended that the wire thread inserts be embedded in the threads of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass fiber reinforced plastic, and plastic to form standard M and MJ threads with continuous strength, The function of impact resistance and wear resistance and can disperse the stress to protect the thread of the base body and greatly prolong the service life of the base body. At the same time, it improves the force of the thread, forms an elastic connection, eliminates the pitch and half angle error between the inner and outer threads, distributes the load on the thread evenly, protects the base thread from damage and prolongs the service life
