Hex head bolts/nuts: Most common, suitable for heavy-duty connections such as engines and suspensions.

Bolts and nuts
Hex head bolts/nuts: Most common, suitable for heavy-duty connections such as engines and suspensions.
Flange nuts: Featuring a large bottom diameter, they eliminate the need for washers, effectively reducing the risk of loosening.
Ball nut: Features a coarser surface texture, can be tightened manually, and is ideal for maintenance applications.
Screw
Self-tapping screws: Screw directly into components to create internal threads, ideal for joining thin metal parts (such as automotive body panels).
Countersunk screw: Its head is conical and flush with the surface of the part, making it ideal for applications where aesthetics are critical (such as interior trim).
Washers and retaining rings
Flat washers: Increase the contact area, reduce pressure, and protect component surfaces.
Elastic washers: Prevent nuts from loosening, ideal for vibrating environments (such as around engines).
Rivets and pins
Solid rivets: Permanent fasteners, ideal for body structures such as car doors and frames.
Retaining clips with open ends: Prevent axial movement and are suitable for wheels and drive shafts.
Special Fasteners
Blind-threaded inserts: Single-sided installation, ideal for panel connections.
Self-tapping fasteners: One-time, permanent connections ideal 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.
