① Fasteners:

Fasteners, often paired with nuts and occasionally accompanied by washers, are integral in applications requiring secure joining and firm tightening mechanisms.

② Nuts:

Nuts are essential companions to fasteners, used to form a complete assembly.

③ Threaded Inserts:

Threaded inserts are typically utilized in standalone fashion, sometimes in conjunction with washers, and are primarily employed for securing or affixing components.

④ Threaded Rods:

Threaded rods are characterized by their threaded ends, with single-headed versions featuring a thread on one side. They are commonly embedded into the structure of a component at one end, while the other end is coupled with a nut to provide a secure connection and maintain tension, often serving a dual purpose of spacing as well.

⑤ Spacers:

Spacers are strategically positioned between the anchoring surface of fasteners, threaded inserts, nuts, and so on, and the surface they support. They are designed to prevent loosening and to distribute the load, thereby reducing stress on the supporting surface.

⑥ Self-drilling Screws:

Components that are to be joined with self-drilling screws do not necessitate pre-tapping for screw holes. As the self-drilling screws are installed, they create the necessary internal threads within the material.

⑦ Rivets:

Rivets feature a head on one end and an unthreaded shaft. During assembly, the shaft is inserted through the connecting parts' holes, and the end of the shaft is then deformed to secure the connection or provide a tight fit.

⑧ Pins:

Pins are inserted into the components during use, typically serving to connect or align parts.

⑨ Retaining Rings:

Retaining rings are typically positioned on a shaft or within a bore and are used to restrict the axial movement of components.

⑩ Wood Fasteners:

Wood fasteners are specifically designed for use in wood, providing a means to join or secure wooden elements.
