What do Fastener Hardware include?

Fasteners include the following 12 types of parts:

1. Bolt: 

Composed of a head and a screw with external threads, it needs to be matched with a nut to securely connect two parts with through holes, and is a detachable connection.

2. Stud: 

Both ends have threads, one end is screwed into a part with an internal threaded hole, and the other end is connected by a nut. It is suitable for situations that require frequent disassembly or connection of thicker parts.

3. Screw:

Composed of a head and a screw, it can be directly screwed into the threaded hole of the connected part without the need for a nut, and can also be used in conjunction with a nut.

4. Nut:

With an internal threaded hole, it matches with a bolt or stud and is used to securely connect two parts.

5. Self tapping screw:

With special threads, it can directly tap threads on thin metal components and achieve fastening.

6. Wood screws:

Specifically used to connect wood, with shallow threads that are easy to screw into the wood.

7. Gasket:

Placed between a bolt, screw, or nut and the connected part, used to increase the contact area, prevent loosening, and reduce wear.

8. Retaining ring:

Used to prevent axial movement of shafts or components on shafts, it is divided into elastic retaining rings and rigid retaining rings.

9. Pin:

Used to connect and position two components, common ones include cylindrical pins, conical pins, etc.

10. Rivet:

It achieves connection through self deformation, has high strength and sealing performance, and is widely used in aerospace, construction and other fields.

11. Assembly and connection pair:

A component formed by combining multiple parts together, used for specific connection requirements.

12. Welding nail:

Fixed connection to a part or component through welding technology, suitable for steel structure construction and industrial manufacturing fields.

These fasteners are widely used in industries such as machinery, construction, electronics, and chemical engineering, and are important components for connecting and fixing components.
