An assembly is a type of fastener that is supplied in combination, such as a certain type of machine screw (or bolt, self-supplied screw) and a flat washer (or spring washer, lock washer); the connecting pair refers to a special bolt, A type of fastener supplied with a combination of nuts and washers. Due to the different types of fasteners consisting of light energy and the nail head (or no nail head), it is fixedly attached to a part (or member) by welding to connect with other parts.

The wire thread insert is a new type of threaded connection element made of high-strength, high-precision corrosion-resistant diamond-shaped wire. It is shaped like a spring and is installed in a specific screw hole of the base body. Its inner surface forms a standard thread. When it is matched with a screw (bolt), the threaded joint strength and wear resistance can be obviously improved; especially in low strength such as aluminum, magnesium, cast iron and plastic. On the material. The locking type is to add one or several turns of the locking ring on the basis of the ordinary type.

It is recommended that the wire screw insert be embedded in the thread of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass steel, plastic, etc. It can form standard M and MJ threads, with continuous strength, impact resistance and wear resistance, and can be dispersed. Stress protects the base thread and greatly extends the life of the base. At the same time, the force of the thread is improved, and the elastic connection is formed, which eliminates the pitch and the half-angle error between the internal and external threads, so that the load on the thread is evenly distributed, and the base thread is protected from damage and the service life is prolonged.
