Bolts and nuts
Hexagonal head bolts/nuts: the most common and suitable for heavy-duty connections such as engines and suspensions.
Flange nut: Large bottom diameter, no need for washers, reducing the risk of loosening.
Roller nut: With a large surface texture, it can be hand tightened and is suitable for maintenance scenarios.
screw
Self tapping screw: directly screwed into the component to form an internal thread, suitable for thin metal connections (such as car body coverings).
Countersunk screw: The head is conical and flush with the surface of the part, suitable for high appearance requirements (such as interior).
Gaskets and retaining rings
Flat washer: increases contact area, reduces pressure, and protects the surface of the component.
Elastic washer: prevents nut loosening and is suitable for vibration environments (such as around the engine).
Rivets and pins
Solid rivets: permanent connections, suitable for body structures such as doors and frames.
Open mouth pin: prevents axial movement, suitable for wheels and transmission shafts.
Special fasteners
Blind thread insert: single-sided installation, suitable for panel connection.
Self riveting fasteners: one-time permanent connection, suitable for panel assembly.

Rivets are widely used across multiple industries. In construction projects, they can be found in applications such as exterior wall decorations, roof structures, and steel-structure connections. In the automotive manufacturing sector, rivets are commonly employed in areas like body-in-white assembly, interior trim installation, and electronic component mounting. Meanwhile, in the aerospace industry, their exceptional strength and stability make them indispensable for building aircraft and spacecraft. In the electronics and appliance field, rivets provide a robust connection between electronic components and their housings, significantly enhancing both the structural integrity and reliability of products—commonly seen in household appliances like televisions, air conditioners, and refrigerators, as well as consumer electronics such as smartphones and tablets. Additionally, in the rail transportation sector, rivets play a crucial role in various applications, including carriage assembly, seat fixation, cable systems, and pipe support structures.
