The primary function of fasteners is to securely join two or more components, ensuring structural stability and safety.
Fasteners are widely used across various industries-including construction, machinery, automotive, aerospace, and electronics-serving as indispensable fundamental components in industrial production.
Fasteners have an extremely broad range of applications. In construction, they are used to connect steel structures, secure curtain wall panels, and support scaffolding; for instance, curtain wall bolts must withstand dynamic loads such as wind pressure and seismic forces, necessitating stringent requirements for materials (e.g., stainless steel) and surface treatments (e.g., hot-dip galvanizing). In automotive manufacturing, fasteners must strike a balance between lightweight design and high strength-such as the use of self-tapping screws or blind rivets for aluminum alloy car bodies. Meanwhile, in electronic devices, miniature screws must provide both precise positioning and resistance to loosening, commonly found in the assembly of products like mobile phones and laptops.
Fastening and joining: This is the fundamental function shared by all fasteners. They secure individual components into a unified assembly-using mechanisms such as threading or riveting-ensuring positional stability and preventing loosening. They are essential components across virtually all manufacturing sectors, including machinery, construction, and electronics.
Choice of detachable or permanent connections: Connections using bolts or screws are detachable, allowing for disassembly without damaging the parts, which facilitates equipment maintenance and repair; conversely, connections using rivets or weld studs are permanent and non-detachable, offering higher structural strength and suitability for fixed assemblies that do not require disassembly.
